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.

OpenMP.org has posted the slides and audio from a day-long tutorial on Hybrid MPI and OpenMP Parallel Programming from SC13. OpenMP is the de facto standard for writing parallel applications for ...

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 ...
