Profiling a Multithreaded program

[singam-sanjay]

Thanks for making this very useful tool open-source!

Can PerfEvent be used in a multithreaded scenario, specifically OpenMP, to,

1. Measure events across all threads?
2. Measure events of individual threads?

Thanks in advance for your answer.

1. All threads that have been started after the PerfEvent object has been created are measured.
2. I'm sure that is possible as well, but would require some changes to the code.
