<DIV><FONT size=2>I don't think Myrinet is a good idea. </FONT></DIV>
<DIV><FONT size=2>If you budget is not a problem, try QLogic's products or
Mellanox's ones. Myrinet maybe cheap but in low reliability.</FONT></DIV>
<DIV><FONT size=2>I prefer to use opensource software with our re-development
for our projects. And generally, re-development will give us flexibility to

Beowulf</DIV>
<DIV><BR></DIV>
<DIV>Hi, there,</DIV>
<DIV> </DIV>
<DIV>First let me salute your dedicated contribution to the beowulf society.
Especially I, a newcomer, have benefitted huge from your
online resource and your QAs. </DIV>
<DIV>I am thinking of building a Beowulf of 17 dual-core nodes, one head node
and 16 computation nodes for material research simulation. I am also a
newcomer to the simulation world, but I have some programming experience (no
parellel programming), knowledge of Unix operating system and a few shell
scripting experience. Equipped with your resorce, I think I can build a new
Beowulf.</DIV>
<DIV>A few questions.</DIV>
<DIV>1. Is Myrinet expandable? </DIV>
<DIV>I mean, if at first, I buy Myrinet for 16 nodes, should I buy more if I
add more nodes to the Beowulf?</DIV>
<DIV>2. When you do Monte-carlo or simulation, do you use commercial software
like MCNPX or Geant4? Which MD simulation and first
principle package </DIV>
<DIV>would you recommend? Will it be good to install them all in one
Beowulf?</DIV>
<DIV>I am looking forward to your guide.</DIV>
<DIV> </DIV>
<DIV>Sincerely,</DIV>
<DIV> </DIV>
<DIV>Rundong Wan</DIV>
