Lately people have been combining MPI and OpenMP, to handle the increasing common architectures of clusters of multi-core machines. Perhaps the hardest problem in parallel computing is load balancing.

In this Let’s Talk Exascale podcast, David Bernholdt from ORNL discusses Open MPI. Bernholdt is the principal investigator for the Open MPI for Exascale project, which is focusing on the communication ...

In this episode of Let’s Talk Exascale, Pavan Balaji and Ken Raffenetti describe their efforts to help MPI, the de facto programming model for parallel computing, run as efficiently as possible on ...
