Hi Jozsef,

Yes, doing +traceoff and instrumenting with user events is one way of accomplishing this. You can also mark the entry methods you're not interested in with [notrace], which tells Charm++ not to trace those EPs.

It may also be worth trying -tracemode summary to see if it is sufficient for your needs.

Thanks,

Ronak

Hi folks,

I would like to collect projections data from a long-running simulation.
I only would like to generate Timelines and Usage profile (under the
Tools menu). Also, I'm really only interested in the cost of a few specific
functions. What is the best way to go about this so data collection with
-tracemode projections do not interfere too much with my simulation?

Should I do +traceoff and instrument the code with
traceRegisterUserEvent() and traceUserEvent()?

How can I ensure that only specific functions are traced?

Thanks,
Jozsef
