ITAC collopprofile details

[mpiuser1]

Hi Intel community,

When using itac --collopprofile is there a way to export the point to point communications that make up the collective communication? Right now it'll list out Process 0 allreduce operation, but is there a way to gather the data of which processes are communicating with others to make up that allreduce operation? It seems for itac --messageprofile it doesn't include the point to point communication that make up collective communication.

Thanks,

Erica

Hi Erica,

Sorry for the delay and that I do not have better news for you:

Intel does not expose the internal communication of collectives.
