<DIV>Well, my grant just through the university's processing and I am already to
purchase my new machine, but I am undecided as to what platform to purchase. My
most computationally intensive work will be in IDL and so I want to
maxamize the speed (and stability) that it runs at. I also want to work on a
unix platform. I recently tested a close twin to the machine I want (I want the
Sun Blade 1000 with 2 x 900 processors, the machine I tested is a SB1000 with 2
x 450 processors), on the IDLSPEC2 benchmark (which I know is flawed, but is the
best available), with these results:</DIV>

<DIV>My questions are:</DIV>
<DIV> </DIV>
<DIV>Why are inexpensive PC archictectures beating pants off of Sun machines
that cost twice as much (but not alphas)?</DIV>
<DIV> </DIV>
<DIV>What are Windows machines ahead of PC linux machines? I would have thought
the oppositive would be true.</DIV>
<DIV> </DIV>
<DIV>Has anyone gone in either direction (Sun to Linux or visa versa) and what
were your experiences?</DIV>
<DIV> </DIV>
<DIV>If I get enough responses, I will post a IDL Sun vs PC summary.</DIV>
<DIV> </DIV>
<DIV>Thanks</DIV>
