Hi,

I have a code which is running let’s say 24hours on a normal workstation with 4 cores. I need to see how it would scale but it’s running part of the time on only one core.

I would therefore like to know how long that code is running is single thread mode compared to multi-threaded mode during its duration.

Any idea how to achieve this?

Thanks

Gilles
