Charm++ parallel programming system

[Alexander Frolov <alexndr.frolov AT gmail.com>]

Hi Phil,

I wanted to try sumdetail option, but got the following error:

Fatal Error by charmc in directory /home/frolo/wdir/dislab/xcharm/trunk/bench/graphs/native/betweenness_centrality

   charmc : No such tracemode sumdetail

charmc exiting...

I am using the mainline charm++ from the git repo.

Best,

The '-tracemode summary' and '-tracemode sumdetail' options may also get you at least some of what you're looking for.

Eric,

thank you for your reply!

I will look into that stats thing. I will share info about the setup for this case, I would be happy. Specifically, I need to count how many times the specified entry method has been called and distribution of this parameter over PEs. Anyway, I will also try to implement it in the application (by using an additional group for collecting this data).

Best,

I don’t believe so without turning on full tracing. If full tracing is on you can look in projections for message counts and number of times entry methods have been executed etc. Another option that I’ve used in the past for my own fine-grained application was to use our user stats tracing with all other tracing turned off. It is a bit more application specific, but gives you a good amount of control over what gets traced.

There is a section on user stats in our manual and if you think that may be useful to you I’d be happy to help more getting it set up with all other tracing turned off.

Hi all! 

I just would like to push this question up. It would be very useful to understand a load balance in the app. 

Thank you!

Hi all & Merry Christmas!

I am wondering does Charm++ support any builtin statistics (without trace collecting)? For instance, I would like to know how many entry methods have been executed per each PE during run time..
