Hi,

I have a few questions that are related to detached MPI communications in StarPU:

1) Do detached communications behave similarly to regular tasks? If not, what sort of limitation do they have? My current interpretation is that a starpu_mpi_*_detached function call will just insert a communication request into a separate communication requested list and a separate communication thread will handle the actual communications when a data handle becomes available. To me, this seems to be analogous to how regular tasks are handled.

2) Does the MPI Insert Task Utility use detached communications?

Best Regards,
Mirko Myllykoski
