Selecting Computing Hardware for CFD Research?

Posted by Cliff on Wednesday December 19, 2001 @08:26AM from the drowning-in-the-numbers dept.

bapya asks: "I am a PhD student working on CFD^? at National Chemical Laboratory, India. We mainly use commercial CFD code (Fluent from Fluent Inc.) and some inhouse codes. Currently we use SGI machines (Origin 200 and O2 family running IRIX), single and dual processor NT machines, DEC alpha and dual processor Linux (running RH 6.2) machines. Now we are planning to upgrade/expand our computational facilities. For the same amount of money (about 25000$), we can buy either a decent unix(IRIX) server (origin 200 dual cpu) or build a much better performing Intel system (either NT or Linux). My professor is in favor of IRIX system. What I would like to ask is what are the criteria for selecting hardware for such a job? and How can one justify the high prices of branded UNIX systems when other systems of same performance level can be built at much lesser costs?"

Re:Fluent Runs on Linux??? by bapya · 2001-12-19 18:36 · Score: 2, Informative

Fluent versions 4.5 and 5 do not run on linux. However, there upcoming version 6.0 (which we are currently testing) runs on linux and is (or will be) supported by fluent.
