| 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 |
