Summary
Cluster Computing - where do clusters fit?
Commodity-based Systems
- Single-node performance and Interconnects
- Prototype Systems; CS1 - CS6
Application performance on Commodity Clusters
- Electronic Structure and Molecular Simulation
- Global Arrays (GAs) ; Linear Algebra (PeIGS)
- GAMESS-UK, DL_POLY and CHARMM
- Materials and Computational Engineering
- CRYSTAL, CPMD & CASTEP and engineering (ANGUS & FLITE3D)
- Comparison with High-end Systems
- Cray T3E/1200E, IBM SP/WH2-375, SGI Origin 3800 Compaq Alpha Server SC and Cray SuperCluster
- Application performance analysis - role of VAMPIR
- Linux Alpha Cluster delivers between 150-400% of T3E/1200E, 82-100% of SGI Origin 3800/R14k-500
CS2 - QSNet Alpha Linux Cluster
% of 32 CPU O3800/R14k-500
