Will Cosmos Motion benefit from multi-core hardware
Peter, the latest ADAMS issues already support multicore solving, and maybe Motion will not support it because now it uses the very reduced version of ADAMS core.

In 2008, does CosmosMotion take advantage of multiple cores during solutions of simulations? Anyone?

Peter,
As far I have tested this damned new motion (which is absolutely inaccurate in results and function-reduced unless it is a full version, comparing to 2007, IMHO), it loads only one processor of 4 that currently I have installed on my PC (Pentium Core2Quad QX6600).

Thanks Basil,
Do you recall if it used all cores in 2007?-

Peter,
The same situation is with 2007. The Motion 2007 uses MSC.ADAMS 2005.2 core which does not support multicore processing.

But it looks like MCS.ADAMS 2005.2 is supporting 8 cores:

Do we somehow get to that interface in SW?-

It's been a little while since I looked into the multi processor support, but I believe it is a switch setting on the solver. It may just be that they have not implemented the switch in COSMOSMotion when intiating the analysis (perhaps a good enhancement request).
I don't recall the performance improvement you get or specifically which areas the gains are in. For example, the biggest time consumer with the solver for most users is with 3-D contact. It seems a perfect candidate for parallel processing since you should be able to compute interferences in parallel.

As far as I know the multicore support in ADAMS was improved only in 2007.1 release, before that time it was very buggy and ineffective and inadjusted.

Yes, I have one motion simulation that took well over a half hour to solve. It inlcuded 3D contact between 8 balls and their respective detents on a combination of 3 separate parts. I noticed the solve time jumped dramatically when I setup the 3D contacts on these items. My machine at work is pretty weak, but I will be upgrading soon and was interested in knowing how much the solution prcess will take advantage of multi-core hardware. It appears that 2008 anmd 2007 doesn't take advantage. I will submit an enhacement request as mentioned and I encourage everyone else to do the same.For example, the biggest time consumer with the solver for most users is with 3-D contact. It seems a perfect candidate for parallel processing since you should be able to compute interferences in parallel.

Peter,
if you are intending to send a request, can you also pick a complaint about MSC.ADAMS Export menu item that does not work in Motion? I will also send the one, but hope together we will make them to respond faster
Regards,Basil.
