any engineers around here? whats the best cpu for LSDYNA/PROE these days

[dannybin1742]

my dad's work keeps buying these xeon servers and apparently they get so hot they cpu throttle when they send huge problems, anyways the terminals they use are all dual xeons and my dad was saying that he was curious how this stuff would run on an amd system. he is looking for a best performance system so he can test some software on it so see how it runs.

are there any mechanical engineers that know this?

currrenlty, even though i'm an amd user, would clock speed matter more for engineering stuff? he does car bumpers

everything is run from win2k

sounds like mathematical crunching, if your looking for raw number crunching it seems the opterons eat the intel offerings alive,esp being cheaper. but windows 2k will never tap into the extra juice you can get from 64bit linux with opterons right now,even though its still faster.

I've worked with some single-proc P4 and Opteron machines using Solidworks and the Opeterons tend to be quite a bit faster, especially when loading and modifying big assemblies. The finite element analysis software similar to LSDYNA (Cosmos/M) used also crunches faster with Opterons.
Since you're using PROE, you might consider running Spec Viewperf's proe benchmark to get a sense of the difference you'll see. I can also bench my Opteron 144 system and get you the #s if you want.

I wish I could help, but my pro/e workstation is a P4 1.7 GHz (and I have one of the better machines @ work).

I'd definitely give the Opteron a test run though, espcially if the Xenon (WTF, they're called Xeon's right?) workstations are heating up too much. I believe the Opteron 150 would be about the fastest single processor solution you could get (except for maybe a 939 based FX-53).

-D'oh!

Try the Hightly Technical forum, maybe Ace's Hardware.
http://www.anandtech.com/it/ has the opterons dancing all over xeons, especially in quad formation and up.

A reference benchmark for these programs and workstations is SPECApc benches. They simulate a real life session with programs like 3DSMax, Maya, Pro/ENGINEER, SolidWorks and Solid Edge.

Here is a database with PROE bench:

Here with SolidWorks bench:

And here with Solid Edge bench:

Well, Opteron workstations outperforms by large margin to Xeon/P4 (all machines are in single CPU configuration, not Dual).
