CPU time tracing

CPU time tracing

Apr-11-10 20:02:53

Hello!

Except for varying the code and taking the simulation-time with a stop watch - Is there any mechanism which can be (ab-)used to find out which function calls need most CPU time in a simulation?

Cheers
Hannes

You can compile the simulation with the -pg flag. And then run gprof afterwards.

That's what the compile omc with when we need to figure which functions take most time anyway. It's probably applicable to simulation code as well.

Thank you for your answer - I'll try that.

Looking for Linux binaries/souces i could only find 1.5.0 RC1. Where can I find the latest RC2 for Linux?

Those are the latest binaries for Linux. Source code can be found on:
Directions for obtaining rc2 sources can be found on: http://www.openmodelica.org/index.php/d … ource-code
Or you could try the very latest version (trunk) if you'd rather use that.
