Use of multiple cores with CATIA

Use of multiple cores with CATIA

Use of multiple cores with CATIA

(OP)
Does CATIA make use of multiple cores during the interactive modeling operations? If I have a quad-core CPU, will I see 100% CPU utilization in task manager or ~25%? The 25% being one core used to its fullest for the CATIA process.

RE: Use of multiple cores with CATIA

Ben, no matter what application that you're running, when looking at the 'Performance' tab on the Windows Task Manager, if you're running a quad-core machine the best that you will see is 25% (50% on a dual-core).  Windows is reporting the distributed use of system resources in terms of CPU usage.

So if your application, whatever it might be, is NOT multi-threaded, the best your will see is 25% even if the application has fully maxed out the processor it's running in.  Now if the application IS multi-threaded, even if it was using multiple cores, the Task Manager will still only report a maximum usage of 25%, but you will see that more than one core is active as tasks are being accomplished so, if you would like, you could think of this as representing MORE than 25% usage but Windows will never report anything along those lines, you have to do the mental math in your head.
