Cosmos & Multiple core 1

[Bouing]

Does Cosmos use multiple core? Does it use it in every aspect (meshing and calculation). I plan to buy the new dell m4400 and don't know what to choose between 2 core at 3 ghz or 4 cores at 2.5 ghz.

Thanks!

I run Solidworks Pro, mostly relatively small (~20k el) nonlinear runs on a dual core machine. I do not see it using both for meshing, but do see both cores maxed out for parts of the solver (nstar). I don't know if Cosmos would even bother with the third and fourth cores... Either confirm with them directly about the quad core or I'd suggest a faster dual core machine. I think the more interesting question is whether to stay 32 bit or go 64 bit for the higher RAM capability.

Thanks,

This is exactly the info I was looking for. Chances are good that Cosmos wouldn't use other cores for meshing but would use then for solving. I don't thing they put a maximum core number on tasks. They just code it so task can be splitted or not.

Bottom line, I'll buy the faster dual core.

Hello,

this is an interesting question.

With a quad-core, Cosmos will run at 68% of all cores, during the solving (not the meshing), using the FFEPlus solver. For the Direct Sparse, it hogs the RAM and runs at 100%.

See brief discussion on scribd. There isn't much concrete information "out there".

That dell m4400 sounds very cool.
