When you run an analysis, you can choose one of 3 solvers to do the analysis for you: Direct Sparse, FFE, and FFEPlus.
I can't tell you the details between the three, but I can tell you that I run direct sparse almost all the time. I expect you should be able to take advantage of this as well, though there may be a benefit of one of the other ones for certain types of analysis.
Using direct sparse, I had a model than ran on our old P4 2.8 GHz system in 29 minutes, which reduced to 11 minutes on our new C2D 6600 system.
We just completed a pretty detailed matrix on the benefits of the various multi-core, multi-proc options. It should be in the Knowledge Base shortly. If someone looks and doesn't see it by end of May, please ping me and I'll see if I can format it to post in this forum.
An unexpected result:
from the few tests I ran, I can say that with Dual Core theimprovement can be really larger than those claimed in thearticle S-02691!
Unhappily the nonlinear solver is still single-CPU!
One welcome enhancement would be dual core/CPU usage by thenonlinear, as this is really the solver that would takethe largest advantage from such a feature.
Thanks to all of your replies, nice to have this knowledgeable group to rely on, as well as SW looking into the comments and requests, thanks Vince
