I just received my copy of the newly published Using Advanced MPI: Modern Features of the Message-Passing Interface. Written by William Gropp, Torsten Hoefler, Ewing Lusk, and Rajeev Thakur, the book ...

While many application tuning guides focus on understanding the performance of an application on a single node, a very scalable application will use multiple node to achieve very high performance.

We describe a program for the parallel implementation of multiple runs of XSTAR, a photoionization code that is used to predict the physical properties of an ionized gas from its emission and/or ...

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 ...

In configuring next generation large scale parallel processing arrays some teams are relying on “heterogeneous processing”. Basically a fifty-cent phrase describing a microprocessor with one or more ...
