Re: [OMPI users] Calculate time spent on non blocking communication?

Okay, so forget about Peruse. You can basically figure that your user process will either be inside an MPI call or else not.  If it's inside an MPI call, then that's time spent in communications (and notably in the synchronization that's implicit to communication).  If it's not inside an MPI

Re: [OMPI users] Calculate time spent on non blocking communication?

Thanks all, As asked the reason of such calculation of non blocking communication, the main reason is that I want to look into the program as how much it percent time is consumed on communication alone, computation alone and the intersection of both. Bibrak Qamar Undergraduate Student BIT-9

Re: [OMPI users] Calculate time spent on non blocking communication?

Again, you can try the Peruse instrumentation. Configure OMPI with --enable-peruse. The instrumentation points might help you decide how you want to define the time you want to measure. Again, you really have to spend a bunch of your own time deciding what is meaningful to measure. Gustavo

[OMPI users] Calculate time spent on non blocking communication?

Hello All, I am using non-blocking send and receive, and i want to calculate the time it took for the communication. Is there any method or a way to do this using openmpi. Thanks Bibrak Qamar Undergraduate Student BIT-9 Member Center for High Performance Scientific Computing NUST-School of
