MPI Applications Support

Intel® Parallel Studio XE Cluster Edition helps exploit scalable parallelism of a modern cluster at all levels of hybrid parallel or sequential computing for a Fortran/C/C++ MPI application: message passing, threading and SIMD / data levels. The Intel® MPI Library is used at the process messaging level. The Intel OpenMP* library, Intel® Threading Building Blocks (Intel® TBB), and Intel® Cilk™ Plus extensions can be used for thread parallelism. The Intel® Math Kernel Library (Intel® MKL) can be used to automatically exploit threading, message passing through ScaLAPACK, and SIMD data parallelism capabilities of Intel hardware.

This section describes the workflow and capabilities for doing performance and correctness analysis of MPI applications using the Intel® VTune™ Amplifier and the Intel® Inspector tools available in Intel Parallel Studio XE Cluster Edition.


The version of the Intel MPI library included with the Intel Parallel Studio XE Cluster Edition makes an important switch to use the Hydra process manager by default for mpirun which provides high scalability across the big number of nodes.
