Requirements

• Low Interconnect Requirement:COBALT, FLUENT

• Medium Interconnect Requirement:Gaussian, ABAQUS, LS-DYNA

• No particular I/O requirement• 1GB per processor RAM requirement• New codes coming:

CHARMM/NAMD

Benchmarking

• Sorry but confidential results

• But. . . .

• While 64 bit processors are perhaps 30-40% faster than Xeon,

• You can buy 5 2/3 Gigabit Xeons for price of one SMP 64 bit processor

Purchase from SGI

• SGI Altix 3700

32 1.3GHz Madisons

32 GB

• Two Atipa Technologies Clusters, each:34 dual 2.66GHz Xeon

34 GB

• SGI TP9100 storage: 1TB
