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.

Product and Performance Information

1

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
