Gaussian 98 A9 Benchnmark timings done by Rich Sudlow on June 2nd 2000. Benchmarks run on 4 processor Sun Enterprise 420R named samson with 2 GB RAM. Processors were 450 MHZ with 4 MB L2 cache. Disk subsytem was a single disk /root & a single disk /scratch. Solaris 7 OS, Fortran & C are version SC 5.0, with performance workshop. All times listed are in seconds.
 
Gaussian Version: G98A9
Gaussian Job Memory: 6 MW unless noted
