Hello

I'm having some issues with my new computer build. Its an i7 920 quad core, with a 64GB SSD, and 12 gigs of OCZ Ram Running windows 7 64bit. I'm using Cosmosworks 2008 coupled with Solidworks 2008 to conduct thermal tests. Unfortunately it seems that no matter what I do, the computer will not use more than 20% of the CPU or and no more than 4 gigs of ram. Is there any way to make it use more or is the program simply not up to the challenge?

Thanks in advance
 
depends if those programs support cuda.. if you are using a nvidia card that supports cuda as well.. then it wouldnt really touch your cpu while rendering.. but outside of intel burn test, prime95 or OCCT you wont find to many programs that can actually push a i7 to its limit..
 
Sorry - I should use better word than rendering. *SIMULATION*. There should be no graphics power that goes into this.
 
Do you see a load on all 4 or 8 cores when simulating? Have you tried prime95 or something similar and seen a load on all cores? Does either program use paged memory when it's running? You might not have a complex enough simulation to use all resources.
 
I see a load on the 4 real cores and it kinda just alternates between really high to nothing CPU wise but it never reaches 100. If it's not complicated enough though and I'm allowing it to use as much of the CPU as it wants shouldn't it try and max out? These simulations take 2 hours or so to run - I want it to minimize the amount of time it takes by using more of the CPU and RAM.

(Btw its only using ~4GB of the ram)
 
are you sure that you are using the 64bit clients for Solidworks and Cosmos? The 32 and 64 bit installs are on different install media and the 32bit client will run on x64.
 
Try to get to the 2009 versions, I found 2008 (SW and FW) to be rather limited with multiple cores. Went to 2009 64-bit (and went from XP64 to Vista 64) and I'm burning through 16 logical cores all near 100% now.
 
Yes it was the 64 bit version

2009 is a great suggestion. I found we had an upgrade disk. The simulation that took me 2 hours to run in 08 took me 9 minutes to run in 09
