1. ABSTRACT

This report compares the performance of a number of different computer systems using the GAMESS-UK software. Two benchmark suites are reported; the GAMESS-UK-89 benchmark that includes a set of twelve quantum chemistry (QC) calculations using the GAMESS-UK electronic structure program, and a second more demanding series of 10 calculations, referred to as GAMESS-UK-97. The comparison involves approximately two hundred computers, ranging from vector supercomputers such as the NEC SX-6i to scientific workstations from HP/Compaq, IBM, Silicon Graphics and SUN, and both 32- and 64-bit CPUs from Intel and AMD.

2. INTRODUCTION

Vector supercomputers used in this report include the NEC SX-6i, SX-5 and SX-4. A large number of workstations and workstation servers have been evaluated, including systems featuring proprietary CPUs from HP/Compaq, IBM, Silicon Graphics and SUN (see below). During the 1990s, workstations based on proprietary RISC CPUs repeatedly demonstrated their cost-effectiveness against vector supercomputers in many scientific applications. Throughout this time, the performance of the family of Intel x86 processors became increasingly competitive, so much so that recent reports in this series have witnessed the x86 CPUs challenging the leading proprietary CPUs from IBM, SGI, Sun, Compaq and HP.

A wide variety of both Intel and AMD commodity CPUs feature in our benchmarking. Historically, these have evolved from Intel's Pentium-based CPUs, with the Pentium Pro (200 MHz), Pentium MMX (233 MHz), the Pentium II (266 - 450 MHz), and Pentium III CPUs (500 - 1 GHz). The Pentium III has now of course been surpassed by its successor, the Pentium 4 - systems benchmarked include those based on the dual processor Xeon CPUs at clock speeds increasing from 2.0 to 3.2 GHz. In addition to Intel's 32-bit IA32 products, we have also benchmarked a number of 32-bit CPUs from AMD, comprising the MP range of dual processor products (with the MP2400+ (2.0 GHz), MP2000+ (1667 MHz) and MP1800+ (1533 MHz) CPUs). Older AMD systems feature the K7 Athlon CPUs (500 - 1400 MHz).

Much has been made of the potential of the new generation of commodity 64-bit processors in scientific and technical computing. Intel led the way with their 64-bit IA64 processor, but have recently been challenged with the emergence of AMD's 64-bit Opteron processor. In response to this challenge Intel have now released their own x86-64 based products, the so-called "Nocona" or EM64T CPUs, with clock speeds increasing from 3.2GHz - 3.6 GHz (the HP DL380 dual-CPU Xeon EM64T running RedHat AS 3.0). All three 64-bit products now feature in these benchmarks.

The first of Intel's IPF products, the Itanium 1 CPU, clearly under delivered; we include here benchmarks based on both the 733 and 800 MHz CPUs. The former appeared in an RX4610 server from Hewlett Packard, a 4-way system with 733 MHz CPUs, featuring 2 MB L3 cache and running the HPUX OS. The 800 MHz Itanium CPU with 4 MB L3 cache also appeared in a 4-way system, running the Linux OS with Intel's 64-bit compilers. The release in 2002 of the second generation Itanium processor from Intel, the Itanium 2 (or McKinley) processor addressed many of the shortcomings evident in its predecessor. Included here are benchmarks from a number of systems featuring the processor, including those from HP (running both the HPUX and Linux operating system), plus a system with the so-called Tiger board from Intel. Systems from HP include the 4-way RX5670 and 2-way RX2600, both featuring 1 GHz CPUs and 4 MByte of L3 cache; the RX5670 is Linux-based, the RX2600 HPUX-based. The corresponding 900 MHz single-CPU Linux system is the ZX6000, with 1.5 MByte L3 cache, running the Linux OS. The system featuring the Intel Tiger board is a 4-way, 1 GHz machine (4 MB L3 cache) running the Linux OS.
Further improvements to the IPF product line arrived in 2003 with the Madison processor. We again include benchmarks from a number of systems featuring this processor, including those from HP (running both HPUX and Linux), from SGI (the Itanium2, Linux64-based Altix systems) and the Intel-based Tiger systems. Systems from HP include both 2- and 4-way systems with a variety of Itanium2 CPUs - 1.2, 1.3, 1.5 and 1.6 GHz. Systems based on the 1.6 GHz Itanium2 include the 2-way HP RX1620 (running both HPUX and Linux64) and the 4-way HP RX4640, running Linux64. The latter system features a 9 MByte L3 cache, while the RX1620 systems feature a 3 MByte L3 cache. The HP RX1620 is enhanced by a FSB clocked at 533 MHz.

1.5 GHz Itanium2 CPU-based systems include the 4-way RX5670 and 2-way RX2600, (with 6 MByte L3 cache), the 4-way RX4640 with 1.3 GHz CPU, plus the 1 GHz CPU-based RX5670 and RX2600 systems (with 4 MByte of L3). The RX5670 and RX4640 are both HPUX-based, while the RX2600 is Linux-based. The SGI system evaluated is the SGI Altix 3700 with both 1.3 and 1.5 GHz CPUs. Intel-based 4-way Tiger solutions include those with both 1.5 and 1.2 GHz CPUs, the latter a prototype.
The 64-bit AMD Opteron systems benchmarked include those on 1.4, 1.6. 1,8, 2.0, 2.2 and 2.4 GHz CPUs in both 2-way and 4-way systems. Two way systems include the Opteron244 (1.8 GHz) and Opteron248 (2.2 GHz), four-way systems the Opteron840 (1.4 GHz), 842 (1.6 GHz), 846 (2.0 GHz), 848 (2.2 GHz) and the Opteron850 (2.4 GHz). These systems are from a variety of vendors, including the HP DL145 dual-CPU 2.2GHz (RedHat AS 3.0), and the V20 and V40z Sun Fire servers (2.2 GHz).

A large number of workstations and workstation servers based on proprietary CPUs have been benchmarked over the past decade. The systems from HP/Compaq, IBM, Silicon Graphics and SUN are listed below.

HP/Compaq/DEC. Several generations of machines featuring the Alpha processor have been evaluated, the most recent including the HP AlphaServer ES45, with both 1250 MHz and 1000 MHz A21264C EV68 CPUs (with 16 MByte L2 cache in the former and 8 MByte L2 cache in the latter). Perhaps a more interesting system was the AlphaServer SC based on EV7 technology. Code-named "Marvel", the 1 GHz processor promised significantly enhanced memory bandwidth compared to the EV68. EV67 processors clocked at 833 MHz feature in the AlphaServer ES40 (again with 8 MByte L2 cache) and in the Linux-based UP2000 dual-processor CPU from API (in the present case with 4 MByte L2 DDR cache). The slower 667 MHz EV67 featured in the API UP2000 and in the Compaq PW XP1000, the DS20E AlphaServer, and the ES40 AlphaServer (with 8 MByte L2 cache). Systems housing the A21264 EV6 CPU include the DEC Alpha 8400/6-575, the entry-level 466 MHz Compaq AlphaServer DS10, the 500 MHz A21264-based machines (the single CPU XP1000 personal workstation, the dual processor Compaq DS20/6-500 and quad processor ES40/6-500 AlphaServer), plus the Compaq GS140 with 525 MHz A21264. Note that the DS10 features a 2 MByte L2 cache, in contrast to the 4 MByte cache of the XP1000, DS20/6-500 and ES40/6-500. Also included is the Samsung AlphaPC 264DP-500, which with 2 MByte L2 cache runs Linux, in contrast to the Tru64 OS on the other EV6-based machines. Retired Alpha systems include the AXP Alpha EV4-based 3000 series and EV5-based 500, 600, 2100, PW AU and 8400 series.
Hewlett Packard, with the most recent PA-RISC based system evaluated being the RP3440 dual-CPU + dual-core PA8800 clocked at 1.0GHz (HP-UX 11.11). Other systems include the Model RP7410 featuring the 850 MHz PA8700+, PA8600 and PA8700 CPUs feature in the HP9000/J6000 (552MHz) and HP9000/J6700 (750MHz) respectively. Older PA8500-systems include the HP9000/785 Model 360 (367MHz), the HP9000/C3000 (400MHz), HP9000/J5000 and 9000/N4000 (440MHz) models. Retired systems include the HP model 9000 series with the PA8000 and PA8200 CPUs, the former in the C160 (160MHz), the latter in the 200MHz HP9000/V2200 (the Exemplar-V class), the HP9000/C200 and in the 236 MHz HP9000/C240 and HP9000/V2250.
IBM, with a wide range of RS6000-based models centred on Power CPU technology. The latest addition to the power series is the power-5 CPU, featured here in the IBM eServer p5 570 (1900 MHz). Power-4+ and power-4 CPUs include the 1.7 GHz power4+ CPU in the 32-way pSeries 690Turbo, and the 1.3 GHz power-4 CPU based-systems, the 8-way IBM pSeries 690Turbo and the 32-way Regatta H node. Benchmark results from both machine are included in this report, together with those from the 16-way Regatta HPC node (in which one of the dual core CPUs is disabled), and the 1 GHz power4 CPU in the 4-way IBM eServer pSeries 630/6C4. Older Power3 RS6000-based models include the 4-way SP Winterhawk2 (WH2) node and IBM RS/6000 44P-270, both clocked at 375 MHz, the 8-way Nighthawk node, clocked at 222 MHz, and the dual processor IBM RS/6000 43P Model 260 (200 MHz). Retired systems evaluated include those based on Power, Power2 and Power2 Super chip (P2SC) CPUs.
Silicon Graphics, with desktop and server machines featuring the MIPS range of processors. The most recent R14k-based machines evaluated include the 600 MHz SGI Onyx 300, and the 500 MHz Origin 3800 and dual processor Origin 300. R12k-based machines include the Origin 3800 (400 MHz), Origin 2000 (300 and 400 MHz), the 270 MHz Octane R12k and O2 R12k, and the 400 MHz R12k Octane 2. Systems featuring the R10k include the Power Challenge, Origin200, O2000, Octane and the ill-fated O2; the R10k CPUs include those rated at 175, 195, 225 and 250 MHz. R5k-based machines include the Indy and O2. Retired machines with the R3000-, R4000-, and R8k-based systems include the Challenge, Power Challenge (PChall.), Indy, Indigo and Indigo2, Crimson, and 4D series.
SUN, with systems based on the UltraSPARC family of processors. The latest UltraSPARC-III Cu-based systems evaluated include the dual 1.056 GHz Sun Blade 2000 and the 8-way Sun Fire V880 with 900 MHz CPUs. Other UltraSPARC-III systems benchmarked include the Sun Blade 1000 Model 1750, with 750 MHz CPU, and SUN Fire 6800/900-Cu. All of these systems feature 8 MByte L2 cache. UltraSPARC-IIi based systems feature the HPC4500 with 400 MHz CPU and Ultra80 (with 450 MHz CPU), both with 4 MByte L2 caches. Retired systems benchmarked include the SPARC-5 and SPARC-10, the HyperSPARC, Ultra-SPARC-1 (Ultra-1/140 and 170) and Ultra-SPARC-2 processors (Ultra-2/200, Ultra-2/300, Ultra30/300 and Enterprise HPC4500, 336MHz).

While now somewhat dated, we also include the evaluation of a number of individual nodes of a variety of Massively Parallel Processors (MPP), including the CRAY T3D, T3E/900 and T3E/1200, the IBM SP2 with both power2-based TN2 and P2SC (120 and 160 MHz) and power3 Nighthawk (222 MHz) and Winterhawk2 (WH2) (375 MHz) CPUs, and the Hitachi SR2201. Figures for the Intel iPSC/860, the KSR-2 from Kendall Square Research, and transputer and i860-based Meiko Computing Surfaces may be found in reference 3.

Machines featuring in this exercise, together with associated configurations, are given in the Appendix. We should stress from the outset that our access to much of the hardware evaluated herein has been at best short lived, and has often involved the temporary loan or donation of machines as part of one of the hardware evaluation exercises run at the Daresbury Laboratory. In many cases these machines were not optimally configured in terms of either memory, or high speed disk, and consideration of the results presented here should be viewed in that light.

Following an introductory evaluation of hardware based on the SPEC Benchmarks (section 3), we present in Sections 4, and 5 results using the GAMESS-UK electronic structure program [4]. Twelve typical applications are included, featuring both conventional Hartree Fock self-consistent field (SCF) and direct SCF, complete active Space SCF (CASSCF) and multiconfiguration SCF (MCSCF), configuration interaction calculations, both direct-CI and conventional table-driven MRD-CI, Moller Plesset perturbation theory (MP2), and both SCF and MP2 analytic 2nd derivatives.

Note that the present results are taken from a more detailed report on computational chemistry benchmarks; the associated MS powerpoint presentation is also available.

3. The SPEC BENCHMARKS

One of the most useful indicator of CPU performance is provided by the SPEC (``Standard Performance Evaluation Corporation'') benchmarks. This benchmark suite contains non-tuned application-based code to measure processor speed for both integer (SPECint) and floating point (SPECfp) arithmetic. While earlier versions of the suite (e.g. SPECmark89) had certain well-advertized flaws, SPECfp95 and SPECint95, and their successors, SPECfp2000 and SPECint2000, have become industry standards in measuring primarily the performance of a system's processor, memory architecture, operating system and compiler.

A SPEC FAQ describing the SPEC benchmark suite and the SPEC consortium is periodically posted to comp.benchmarks, and can be found on the WWW at

http://www.specbench.org/spec/faq

An excellent summary of the SPEC benchmarks that was periodically updated is available via anonymous ftp from ftp.cs.toronto.edu in the file /pub/spectable. This posting terminated in December 2000 with the arrival of SPEC2000. More SPEC-related information is available at the SPEC WWW site,

and at the Performance Database Web site,

3.1 SPEC CPU2000 Benchmarks

The current generation of SPEC benchmarks, SPEC CPU2000,

http://www.specbench.org/osg/cpu2000/results/cpu2000.html

comprises a number of separate listings including CFP2000 and CINT2000. The former is derived from the results of fourteen floating-point benchmarks compiled with aggressive optimization. It is the geometric mean of fourteen normalized ratios (one for each floating-point benchmark). CINT2000 is derived from the results of twelve integer benchmarks compiled with aggressive optimization. It is the geometric mean of twelve normalized ratios (one for each integer benchmark). Note that the level of optimization is not mandated. While highly aggressive optimization is permitted, results derived from benchmarks compiled with conservative optimization (as in SPECfp_base2000) can be submitted.

It is perhaps worthwhile at the outset to consider the potential shortcomings of using single processor benchmarks, such as SPECfp2000 or SPECfp2000_base, on the current generation of SMP-based clusters. The nature of the associated cache hierarchy and memory architecture need to be considered, both arguing for a consideration of not only the SPECfp values, but also the related RATE benchmarks (SPECfp_rate). The complex cache hierarchy of systems such as the 8-way IBM 690Turbo means in practice that with 7 of the 8 CPUs disabled (according to the SPECfp2000 rules), a given single processor benchmark is actually running in an environment comprising the total L3 cache associated with the 8-way MCM i.e. 128 MByte. Since many of the SPECfp2000 benchmarks have a total memory requirement of this order of magnitude, the recorded level of performance arguably bears little resemblance to what might be seen if, for example, all 8 CPUS were running the same job. A second effect is that of the memory architecture of the SMP node in question; in many instances the effective memory bandwidth available to a given job will decline significantly as more of the CPUs are involved in processing. The impact of this effect will be critically dependent on the nature and bandwidth demands exhibited by the application. The impact of L3 cache utilisation and memory architecture may be partially quantified by considering the associated SPECfp2000_rate figures for such systems. Both effects should be considered when considering all the single CPU results presented in this paper.

The current set of CPU2000 results are given in Tables 1 (SPECfp2000) and 2 (SPECfp_base2000) (with the baseline system the Ultra 10 333MHz). In each case we have normalised the values relative to those of the 1.5GHz Itanium2 CPU in the HP Integrity RX5670 (both SPECfp2000 and SPECfp_base2000 values of 2108).

An examination of the SPECfp2000 values of Table 1 demonstrates the dominant position of the Intel's 2nd generation Itanium2 processor (Madison) with 20 of the leading 30 systems featuring this processor. The only other CPU to feature in the top 30 systems is IBM's power5 processor (the 1.9 GHz CPU in the eServer p5 570, the 1.65 GHz CPU in the i5/p5 550 and 520 eServer systems, and the 1.5 GHz CPU in the p5 520 Express). Considering the leading systems of Table 1, we note:

Within the leading 30 systems, SPECfp2000 ratings for the Itanium2 processors may be broadly classied according to both clock speed and size of L3 cache. For the 1.6 GHz CPU, we find ratings of between 2712 (HP RX4640 with 9 MB L3 cache) to 2545 (Dell PowerEdge 7250 with 3MB cache), although we note the rather poor rating (2001) reported for the I2X2 system from ION Computers. It is noticeable that the size of cache (and associated cost) does not have a major impact on the SPECfp ratings e.g. the SGI Altix 3700 Bx2 ratings of 2647 and 2600 for systems with 9MB and 6MB of L3 cache respectively. Systems based on the 1.5 GHz processor exhibit SPECfp2000 ratings from 2502 (HP Integrity RX4640 with 4MB L3) to as low as 1830 (Supermicro SS6113M-i with 6MB L3). The latter is little better than the value of 1817 (in the 1.4 GHz-based I2X2 system from ION Computers) and 1814 (the 1.3 GHz Integrity RX5670 system from HP). These may be contrasted with figures for the older Itanium2 systems ranging from 1410 (the 1GHz CPU in the SGI Altix 3000) to 1086 (the 900 MHz CPU in the HP ZX2000 system).
Historically two sets of values were typically given for the Itanium2-based systems from HP - corresponding to execution under HPUX using HP's f90 compiler (tagged "H" in the tables), and to execution under Linux running Intel's efc/ifort compiler ("L"). While the HPUX-based figures were initially higher than those based on ifort, the improvements from version 7.0 onwards of the Intel compiler have reversed this trend. We would expect this situation to remain fluid as new releases of both compilers are made available. It is noticeable that the vast majority of the efc-based figures are all SPECfp_base figures; few optimised SPECfp2000 ratings have been published to date.
With a SPECfp rating of 2702, the 1.90 GHz power5-based IBM eServer p5 570 outperforms the 1.65 GHz power5 CPU by factors of between 1.13 (the eServer p5 590) and 1.28 (the p5 520 Express). These factors increase to 1.59 and 2.13 respectively when compared to the older 1.7 GHz power4+ and 1.3 GHz power4 CPUs, both in the pSeries 690Turbo series.
Considering the Pentium 4 and associated Xeon systems, we find ratings as a function of clock speed of 1842 (3.80 GHz Intel D925XECV2), 1724 (Intel D925XECV2 3.46 GHz P4), 1631 (Supermicro Super P8SC8 3.80 GHz P4) and 1630 (Intel D925XCV, AA-400 3.6GHz P4) and 1597 (HP ProLiant BL20p G3 3.6GHz Xeon). The 3.80 GHz D925XECV2 is seen to exhibit a rating close to that of the 1.3GHz Itanium2 in the SGI Altix 3000 series (1854).
The leading x86-64 system from AMD is the 2.6GHz Athlon64 (MSI K8N Neo2 FX-55) which, with a rating of 1878, is slighly ahead of the 3.80 GHz Intel D925XECV2 (1842) and of comparable speed to the Itanium2 1.5GHz/6ML3 in the Dell PowerEdge3250 (1875). Other x86-64 ratings as a function of clock speed include the 2.6GHz FX-55 (1782, AMD MSI K8N Neo2) and ratings for the 2.4GHz Opteron systems ranging from 1644-1849 (1849, Fujitsu CELSIUS V810 / Opteron250; 1787, Sun Java Wrkst. W1100z; 1771, IBM eServer 326; 1701, HP ProLiant DL145 Opteron250; 1693, Sun Fire V20z Opteron250, and 1644, AMD ASUS SK8V/Opteron150)
While the leading UltraSPARC-based systems from Sun are now well off the leading pack (see below), the SPARC64-based systems from Fujitsu remain competitive, with the 1890 MHz CPU in the PrimePower900 series exhibiting a rating of 1803.
Considering the final variant of the Alpha processor, the EV7, we find ratings of 1684 in the 1.3 GHz-based AlphaServer GS1280, 1494 in the 1.1GHz-based ES80 and ES47, and 1288 in the 1 GHz ES47. Ratings for the older EV68 processor include values of 1365 for the AlphaServer ES45 Model 68/1250 (A21264C) - this CPU outperforms the DS25 68/1000 (985) and ES45/1000 (960) by factors of 1.35 and 1.39. These factors are greater than the clock speed ratio of 1.25, caused in large part by the increased cache on the 68/1250 (16 vs. 8 MByte).

While the top 50 systems exhibit greater than 63% of the performance of the 1.6 GHz-based HP Integrity RX4640 (i.e. SPECfp2000 figures higher than 1700), only 6 distinct CPUs are involved in these systems, namely IBM's power5, Intel's IA64 Itanium2 and IA32/EM64T Pentium 4 Xeon processors, AMD's Athlon64 and Opteron CPUs, and finally the SPARC64 GP from Fujitsu.

Forty of the next 50 entries (SPECfp ratings from 1441-1659) feature either the Pentium 4 / Xeon IA32 CPUs or x86-64 systems from AMD, with 30 systems from Intel and 10 from AMD. The remaining 10 systems include four pwr4+ systems from IBM, four EV7 systems, and two of the slower Itanium2 systems (1.4 GHz with 1.5 MB L3 cache).

All other CPUs exhibit SPECfp2000 ratings of less than 1440 i.e. are a at least a factor 1.88 times slower than the 1.6GHz/9MB Itanium2 in the HP Integrity RX4640. Other figures worth noting on the leading machines from other vendors include:

1353 and 1349 for the 1600 MHz UltraSPARC IIIi CPU in the Sun Blade Model 2500 and Sun Fire V440 respectively. Based on the former figure, the 1600 MHz CPU is outperformed by the HP RX4640 Itanium2 by a factor of two.
An estimated value of 1000 for the 1 GHz dual-core PA8800 CPU in the HP 9000 Model RP3440 and 674 for the 875 MHz PA8700+ in Hewlett Packards HP 9000 Model C3750. The HP 9000 Model RP3440 would thus be ranked at around position 250 in the SPECfp2000 list. Note that the PA8800 is essentially identical to the other PA2.0 CPUs - with higher frequency, more L2 cache, dual-core and uses the same bus the Itanium2 uses (200MHz@128bit double pumped). Thus in most cases the PA8800 is performing roughly like a Itanium2 1.0GHz system, not unexpected given use of the identical memory bus, virtually the same number of functional units and the same frequency (considering the old 1.0GHz Itanium2).
982 for the x86-32 2.20 GHz CPU from AMD (ASUS A7N8X Motherboard in the XP 3200+) and 659 for the dual processor 2.00 GHz CPU in the MP2400+).
529 for the MIPS R14k/600 MHz CPU and 463 for the R14k/500 MHz CPU, both in SGI's Origin 3200. The SGI Origin 3200 / 600MHz R14k is ranked at position 403 in the SPECfp2000 list.
456 and 440 for the 1.4 GHz and 1.26 GHz Pentium III respectively in Dell's Precision PowerEdge 1500SC WorkStation. The PentiumIII is now a factor of four slower than the 3.8 GHz Pentium 4.
434 for the 450 MHz RS/6000 power3 CPU in IBM's RS/6000 44P-170, and 382 for the 375 MHz CPU in the IBM RS/6000 SP-375MHz T/W.

Summarising the above discussion, normalised ratings for the leading proprietary and commodity-based CPUs from each vendor normalised with respect to the HP Integrity RX4640 1.6 GHz Itanium2 (9MB L3 cache) and the values of Table 1 are as follows:

100% - HP Integrity RX4640/Itanium2 1.6 GHz/9MB (2712);
100% - IBM eServer p5 570 (1900 MHz) (2702);
98% - SGI Altix 3700 Bx2/Itanium2 1.6 GHz/9MB (2647);
95% - Bull NovaScale 4040, 1.6 GHz Itanium2 with 9MB L3 cache (2566);
94% - Dell PowerEdge 7250, 1.6 GHz Itanium2 with 9MB L3 cache (2545);
75% - ION Computers I2X4, 1.5 GHz Itanium2 with 9MB L3 cache (2043);
69% - AMD MSI K8N Neo2 motherboard with 2.6 GHz Athlon64 FX-55 (1878);
69% - Intel D925XECV2 3.80 GHz Pentium4 (1873);
66% - Fujitsu PrimePower900, 1.89 GHz SPARC64 V with 3MB L2 cache (1803);
66% - SUN Java Workstation W1100z (2.4 GHz Opteron) (1787);
62% - HP AlphaServer GS1280, 1.3 GHz EV7 (1684);
50% - Sun Blade Model 2500, 1.6GHz UltraSPARC IIIi (1353);
37% - HP 9000 Model RP3440, 1.0GHz PA8800 (1000); and,
19% - SGI Origin 3200/R14k-600 (529) and 17% for the Origin 3200/R14k-500 (463).

In terms of leading proprietary CPUS from each vendor, it is clear that both MIPS-based systems from SGI and PA-RISC systems from HP, and, to a lesser extent, both Alpha EV7/EV68 systems from HP/Compaq and UltraSPARC systems from Sun, are now eclipsed by the commodity IA64 and x86-systems from Intel and AMD. Indeed, the main products now offered by all four vendors feature some combination of the latter CPUs.

Finally, we would point out a number of issues around the present benchmarks and their potential relationship to the SPEC benchmarks:

Some issues need to be considered when comparing the SPECfp2000 ratings with the results of the present benchmarking exercise. Many of the published figures rely on utilities that were not available in the current benchmarking exercise e.g., "spike", and it may be more meaningful in such cases to draw comparisons with the corresponding SPECfp_base values.
When considering the present benchmarking results, there are several factors we wish to consider in assessing the usefulness of the SPEC ratings;
- Do the SPECfp values provide a reliable metric for evaluating the capabilities of hardware in computational chemistry? If so, we would expect to find a close mapping of the ratios for the various chemistry benchmarks onto the SPECfp ratios;
- Does any particular CPU consistently ``underperform'' based on the SPECfp criteria? - this would manifest itself as the ratios from the chemistry benchmarks falling below the SPECfp ratios e.g., the impact of the memory problems of the SGI O2-R12k and R10k [6] impacting on the benchmarks.
- As discussed above, we should consider the potential shortcomings of using single processor benchmarks such as SPECfp2000 on the current generation of SMP hardware. The only way to quantify this effect is to generate the associated "rate" figures for the machine in question. We note that the current set of SPECfp2000_rate figures are given in the more detailed report, computational chemistry benchmarks.

4 THE GAMESS-UK BENCHMARK

The GAMESS-UK-89 benchmark summarised below was designed to reflect the typical range of calculations performed by the ab initio quantum chemist. It includes 12 calculations carried out using the GAMESS-UK electronic structure code, and includes the following functionality;

Conventional SCF Calculations, on morphine and 2,4,6 tri-nitro-toluene (Calculations 1. and 2. respectively);
Valence-only ECP calculations, with a geometry optimization of Na ₇Mg⁺ in an ECP-DZ+D(Mg) basis of 70 GTOs (calculation 3).
A Direct-SCF calculation on Cytosine (82 GTOs, 6-31G basis) Calculation 4);
Multi-configuration SCF calculations, with a CASSCF geometry optimization on H₂CO (Calculation 5), and a larger CASSCF calculation, also on H₂CO (Calculation 6);
Configuration interaction calculations, both Direct-CI on the H₂CO/H₂ +CO TS transition state (Calculation 7), and conventional table driven-CI on TiCl₄ (Calculation 8);
Moller Plesset calculations, with a MP2 geometry optimization of H₃SiNCO (Calculation 9);
Analytic second derivatives, at both the SCF (C₅ H₅N molecule in a 6-31G basis, Calculation 10) and MP2 level (C₄ in a 6-31G* basis, Calculation 11);
A Direct-MP2 calculation on C₅H₅N in a DZ + D(N) basis set (Calculation 12).

The data presented in Table 2 is collected under control of the UNIX command time where available, and includes CPU time (both user and system), total elapsed time and Efficiency, measured as CPU versus elapsed. While our original aim was to base comparisons strictly on elapsed times, such timings could not be consistently gathered over the range of machines considered. For example, the range of disk configurations varies enormously, from primitive SCSI disks to striped high-speed raid disks, and the loading on the machines varies, from effectively single-user loading on many of the workstations, to multi-user environments, such as on the DEC Alpha 8400/5/300. Thus while reporting the elapsed times, we use such figures to identify, where appropriate, the requirement for enhanced disk configurations, rather than as any implied criticism of the machine in question.

The total user CPU timings of Table 2 refer to the summed user CPU timings over all 12 calculations of the GAMESS-UK-89 benchmark. In each case we have normalised the performance against that found on the 1.5GHz Itanium2 CPU in the HP Integrity RX5670

4.1 GAMESS-UK-97 BENCHMARK

The GAMESS-UK-97 benchmark summarised below is designed to reflect a more demanding range of calculations performed by the ab initio quantum chemist. It includes 10 calculations carried out using the GAMESS-UK electronic structure code (Version 6), and includes the following functionality;

A Direct-SCF calculation on Morphine (227 GTOs, 6-31G basis); the calculation converges in 9 SCF cycles (Calculation 1);
Conventional SCF Calculation on 2,4,6 tri-nitro-toluene (6-31g** basis, 265 GTOs); requires 11 iterative SCF cycles and uses 2e-integral format (Calculation 2);
DFT B3LYP calculation on Cytosine (167 GTOs, 6-311G* basis) conventional SCF converging in 10 SCF cycles, high quadrature (Calculation 3);
CASSCF Multi-configuration SCF calculation on H₂CO (Calculation 4) conducted in a CC-PVTZ basis of 100 GTOs. The 16 electrons in 13 MOS (109857 csfs) converged in 3 macro-iterations;
Direct Configuration interaction calculation on the H₂CO/H₂ +CO TS transition state (Calculation 5). Conducted in a CC-PVTZ basis of 100 GTOS (88 spherical harmonics), the in-store calculation included 1,629,857 CSFs generated from 16 reference functions;
A coupled cluster CCSD(T) calculation on the C4 molecule conducted in a tzv+2D+1F basis of 144 GTOs; a total of 172,811 configurations (CCSD) (Calculation 6);
Moller Plesset calculations, with a MP2 geometry optimization of H₃SiNCO (Calculation 7); TZVP basis (105 GTOs), 5 energy and 5 gradient calculations for convergence;
Analytic second derivatives, at both the SCF (C₅ H₅N molecule in a 6-311G** basis, (144 GTOs, Calculation 8) and MP2 level (C₄ in a TZVP basis (2D on carbon, 104 GTOs, Calculation 9);
A Direct-MP2 energy calculation on Cytosine in a 6-31g* basis set (130 GTOS, Calculation 10) requiring 2 integral passes.

The data presented in Table 3 is collected under control of the UNIX command time where available, and includes CPU time (both user and system), total elapsed time and Efficiency, measured as CPU versus elapsed.

The total User CPU timings of Table 3 refer to the summed user CPU timings over all 10 calculations of the GAMESS-UK-97 benchmark. In each case we have normalised the performance against that found on the 1.5GHz Itanium2 CPU in the HP Integrity RX5670

5. SUMMARY

As a summary of this work, we present in Table 4 the relative performance of 200 CPUs against the HP RX5670 Itanium2/1500-H in terms of the CPU2000 benchmarks, and those from the present Matrix-97, Chemistry Kernels, GAMESS-UK and DL_POLY benchmarks. Note that while previous versions of this report have driven this comparison across the CPU95 ratings, we have now attempted to transition to CPU2000. In doing this, we clearly have a problem in terms of relating older machines, for which only SPECfp95 results are available, with the newer systems. Thus many of the SPECfp entries of Table 4 are estimated CPU2000 figures based on extrapolations from the older CPU95 values. This extrapolation process has involved identifying systems for which both SPECfp2000 and SPECfp95 figures are available, deriving appropriate scaling factors based on these values, and applying this scaling to the older CPUs. While not an ideal metric, we would suggest this approach is preferable to the alternative of trying to derive extrapolated SPEC95 figures from measured SPECfp2000 figures for the more recent systems.

In terms of performance ordering of CPUs, we find that the PI values and all the chemistry benchmarks are broadly in line with the SPECfp predictions, with the notable exceptions mentioned above.

In theory the O2-R10k should have outperformed the corresponding Indigo2; with better memory bandwidth, superior I/O and more tightly coupled integration it should have done well. However SGI made a design decision which has seriously impaired the performance of the O2 in some application areas. It took about 3 months for this "flaw" to be fully identified. Until December 1996, SGI were claiming that the O2 R10k would perform in the region of 10, 12 or even 15 SPECfp95. Indeed on some benchmarks it does indeed achieve performance that matches these figures. However, the O2 has a Unified Memory Architecture which uses main system memory as memory for the graphics display and operations. Despite the impressive bandwidth figures for the O2, it does seem that the O2 memory architecture severely impedes the performance of the R10k processor, particularly when compared with the Octane, Indigo2 and Origin systems. This is shown by the SPEC comparisons of Table 1; we suspect that the two main factors limiting performance in the memory subsystem are the main memory speed and the CRIME chip.

The CRIME chip, which acts as the memory interface between the memory and the three drains on it - the CPU (800 MByte/second), I/O engine (500 MByte/sec) and the monitor display (700 MByte/second) - is probably the main bottleneck. This chip was designed to work as a built in memory controller, but the design was biased toward the R5k; it can't work directly with the R10k because the R5k expects 32 byte cache refills while the R10k wants to have 64 or 128 byte refills. Therefore SGI supply a custom ASIC with the R10k daughter board. This interfaces the R10k's level 2 cache with the CRIME chip. Performance problems are caused by the ASIC having to break each 128 byte cache refill operation into 4, 32 byte refills. The net impact of this effect is that the O2 R10k will only work well with problems that fit into the L2 cache (1 MByte). Not surprisingly, the memory intensive SPECfp95 figures are badly affected, although the impact on less memory intensive applications is not so severe. It should be noted that this type of incident is very rare; chips often fail to deliver but not system architectures designed for existing chips.

More evidence of the poor performance of Sun Fortran f90 Compiler is shown in the following figures Linpack 100X100 all Fortran benchmark kindly provided by Hans-Hermann Frese of ZIB, Berlin. The results using different Sun Fortran compiler releases on a Sun Ultra 60 Model 2360 used one UltraSPARC CPU at 360 MHz. The performance of the latest NAGWare f95 is also compared:

**Linpack 100X100 Performance as a function of FORTRAN compiler.**
Compiler	Options	Linpack 100X100
Sun f77 4.2	-fast -O5	164 Mflop/ s
Sun f77 5.0	-fast -O5	166 Mflop/ s
Sun f90 1.2	-fast	61 Mflop/ s
Sun f90 2.0	-fast -ftrap=no%division	68 Mflop/ s
NAGWare f95 4.0	-Wc,-fast	166 Mflop/ s

These figures underline that the performance compiler is still poor compared with Sun's Fortran Surprisingly, the performance of the NAGWare produces intermediate C code is as good as Sun's compiler.
