Processor Identification

Is there a way in Java to identify the processor that the current thread is assigned to?

OK, but still it is something very JVM/OS/machine specific and so I doubt there is any way to do it in Java. I would say that your best bet would be to look at it from the other way, get you OS to tell you where/when threads of your java app are scheduled. Eg. a simple windows based approach is to check out Task Manager and look at the load on the processor cores. I am sure that are other methods available for other OS's and that are more sophisticated ways of doing it too.

Basically, it's the OS's scheduler that determines where threads run (java threads or others alike) and so that is where you need to hook to get that information, and since that would be OS specific, it is highly unlikely that Java would be able to get the info.

No, and it wouldn't make sense anyway. There is never a guarantee that the same processor/core will always execute the code for a particular thread. Therefore if there were such a call, the result would be useless as by the time it returns a result to your code, the code may be executing on a different processor/core!

I probably stated the question in the wrong way. What I want is to assess how many processors are executing threads of my program.
