Tips and tricks on how to get the optimal performance settings for your mixed Intel MPI/OpenMP applications.
The upcoming OpenMP 4.0 will be discussed at SC12, and there wil
This article looks at several books that introduce developers to the topics of Message Passing Interface (MPI), parallel programming, and OpenMP*.
The Intel® MPI Library and OpenMP* runtime libraries can create affinities between processes or threads, and hardware resources. This affinity keeps an MPI process or OpenMP thread from migrating to a different hardware resource, which can have a dramatic effect on the execution speed of a program.
In this article an OpenMP* based implementation of the Ant Colony Optimization algorithm was analyzed for bottlenecks with Intel® VTune™ Amplifier XE 2016 together with improvements using hybrid MPI-OpenMP and Intel® Threading Building Blocks were introduced to achieve efficient scaling across a four-socket Intel® Xeon® processor E7-8890 v4 processor-based system.
How to resolve a missing lsb package on SLES* 12.
There are two principal methods of parallel computing: distributed memory computing and shared memory computing. As more processor cores are dedicated to large clusters solving scientific and engineering problems, hybrid programming techniques combining the best of distributed and shared memory programs are becoming more popular.
In this article, we present a tutorial on how to start using MPI SHM on multinode systems using Intel® Xeon® and Intel® Xeon Phi™ processors. The article uses a 1-D ring application as an example and includes code snippets to describe how to transform common MPI send/receive patterns to utilize the MPI SHM interface. The MPI functions that are necessary for internode and intranode communications...
This is the second article in a series of articles about High Performance Computing with the Intel Xeon Phi.
