Ok ... I have finally finished the simple comparison on different kernels and computational speed. I ran a commercial code that required memory (lots of matrix solutions) and large amounts of CPU times. Recall that I previously posted the times, stating I was disappointed in the speedup from a PIII 700 MHz. The results are listed below. The AMD machine was dedicated to this problem - nothing else was running at the time. PIII 700 MHz (dual CPU - only 1 used for solution) 96,370 secs - Win2000 AMD XP 2100+ (single CPU) 686 kernel (?) 65,039 secs AMD XP 2100+ (single CPU) Athlon kernel 63,411 secs - Linux RH7.2 No real improvement in performance. I must say I am disappointed in the speedup. Based on benchmarks (specfp) I was anticipating better performance - something in the 50,000 range. But of course I have a different motherboard and the type of problem I was solving would only be represented by a portion of the average specfp results. My guess is that for the problem type I work with and the motherboard (ABIT) - I may have been expecting too much. Thoughts / comments welcomed. Randy Clarksean, Ph.D., P.E.
