<DIV><FONT face=Arial size=2>I just put together a new AMD XP 2100+ system
and installed RedHat 7.2 The intent of this machine is heavy computational
work (1.5 GB RAM, 80 GB HD, ABIT Motherboard with PC2100 RAM). I have an
older Win2000 Machine, dual PIII 700 MHz 1 GB RAM - TYAN Motherboard that
I have been using for computational work. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have data from an analysis run on the PIII system
(1 CPU) and I just ran that same analysis on the new AMD21+ system. The
speed improvement was NOT what I hoped for.</FONT></DIV>

<DIV><FONT face=Arial size=2>I do realize that there are operating system
issues, etc. ... but with all of that I had anticipated a larger reduction in
computational time. The code I am running is a commercial code that is
developed to run on both operating systems, so I am fairly sure they work to get
the best CPU time on both platforms. I was hoping for something on the
order of 1/2 the CPU time - on large computational runs like this every little
reduction in time helps.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Not being a "kernel" expert by any means ... would
it make any sense to recompile the kernel on my new platform, rather than
relying on the kernel as loaded from the RH7.2 distribution CDs? Any
suggestions would be greatly appreciated!</FONT></DIV>
