It is very rare indeed to get benchmark data on HPC applications that shows it scaling over a representative number of nodes, and it is never possible to get cost allocations presented that allow for ...

MPI (Message Passing Interface) is the de facto standard distributed communications framework for scientific and commercial parallel distributed computing. The Intel MPI implementation is a core ...

There is some debate in the InfiniBand community about whether HCAs should employ on-load or off-load protocol processing. Adherents of each camp claim higher performance. In this article, we will ...
