<DIV><FONT face=Arial size=2>Ok ... I have finally finished the simple
comparison on different kernels and computational speed.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>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.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>PIII 700 MHz (dual CPU - only 1 used for
solution) 96,370 secs</FONT></DIV>
<DIV><FONT face=Arial size=2> - Win2000</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>AMD XP 2100+ (single CPU) 686 kernel
(?)
65,039 secs</FONT></DIV>
<DIV><FONT face=Arial size=2>AMD XP 2100+ (single CPU) Athlon
kernel
63,411 secs</FONT></DIV>
<DIV><FONT face=Arial size=2> - Linux RH7.2</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=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.</FONT></DIV>
