Hi,
I have a program where each MPI rank hosts a set of data blocks. After
doing computation over *some of* its local data blocks, each MPI rank needs
to exchange data with other ranks. Note that the computation may involve
only a subset of the data blocks on a MPI rank. The data exchange is
achie
Thanks Jeff! That's very helpful.
Cheers!

OpenMPI process to accelerate my application on multicore CPUs. My
application is already built on OpenMPI, but it currently exploits
parallelism only at the process level.
I am wondering if anyone can point me to some
