Gaussian 98 A9 Benchnmark timings done by Rich Sudlow on Oct 5, 6th 2000. Benchmarks run on 20 processor SGI Origin 3000 named o3000.hpcc.nd.edu with 8 GB RAM. Processors were 400 MHZ with 8 MB L2 cache. Disk subsytem was a 6 disk stripe using FC disks. Irix 6.5.9 OS, Fortran & C are version 7.3, with SCSL Scientific Library 1.3. All times listed are in seconds.
Gaussian Version: G98A9
Gaussian Job Memory: 6 MW unless noted
