Gaussian 98 A11.4 Benchnmark timings done by Ken Dieter (SGI) on April 1st, 2003.  Benchmarks run on 8 processor SGI Altix Model 3300 named ferarri.americas.sgi.com with 8 GB RAM.  Processors were 900 MHz Itanium 2  with  1.5 MB L3 cache. Gaussian was compiler with Intel Version 6 compilers.. All times listed are in seconds.
Gaussian Version:  G98A11.4
Gaussian Job Memory:  6 MW unless noted
