Re^2: New PC GAMESS benchmarks data

The Wall clock times can be found in the corresponding output files. Typically, they are close to CPU times. The only exception is Test #2, which is partially limited by disk I/O on systems with relatively small amount of installed RAM. This is the only reason why both CPU and Wall clock times are provided in this case.

As for now (I guess) dual-core machines have optimal price/performance ratio. From the other hand, simultaneous access of two processes to the shared memory and disk can be a bottleneck on a some kinds of jobs. Please, can you give also wall clock times.
