Hi cluberti, I tried using the 64-bit COSMOSWorks with Affinity set to 1 CPU and all CPUs and the CPU usage and solution time were the same. The CPU usage and solution time for all 4 settings were 25% and 4 min 22 sec. Windows XP 64-BIT & COSMOSWorks 32-BIT # of CPU---------------CPU Usage----------------------Solution time (min:sec) 1------------------------25%-----------------------------------4:22 2------------------------25%-----------------------------------4:21 3------------------------25%-----------------------------------4:22 4------------------------25%-----------------------------------4:21 When I uninstalled 64-bit COSMOSWorks and installed the 32-bit version. The following results were obtained: Windows XP 64-BIT & COSMOSWorks 64-BIT # of CPU---------------CPU Usage----------------------Solution time (min:sec) 1------------------------25%-----------------------------------8:50 2------------------------50%-----------------------------------5:51 3------------------------75%-----------------------------------5:34 4------------------------99%-----------------------------------3:13 So, the 32-bit software is not limiting the CPU usage unlike the 64-bit version. This is the software from the same company Has any body ever confront with this problem (even if it's on another software) and what did you look for to solve this issue? Any input is greatly appreciated. Thank you!!

Good morning! I have a quick question about the CPU usage limitation in the XP 64-bit. I am running a computational demanding software (COSMOSWorks - Finite Element Analysis) and the problem is COSMOSWorks FEA software (64-bit) is only using 25% of the CPU. The computer has 2 Intel Xeon 5140 (dual cores) so in the "Task Manager" it seems like it has 4 CPUs but the FEA "process" is only using 25% and will not go any higher. I have tried setting the Affinity in the Task Manager to CPU 0, CPU 0 & CPU 1, CPU 0 - 1 - 2, and CPU 0-1-2-3. All of the combinations only use 25%. At which point, I installed 32-bit software and I am able to control the CPU usage which goes from 25% for 1 CPU to 100% for 4 CPUs. Would anyone know how to change the CPU utilization for the software? Thank you very much!
