Intel® MPI Library 5.0 Beta Readme

The Intel® MPI Library is a high-performance interconnect-independent multi-fabric library implementation of the industry-standard Message Passing Interface, v3.0 (MPI-3.0) specification. This Beta package is for MPI users who develop on and build for Intel® 64 architectures on Linux* and Windows*, as well as customers running on the Intel® Xeon Phi™ coprocessor on Linux*. You must have a valid license to download, install and use this product.

  • Best Known Method: Avoid heterogeneous precision in control flow calculations

    Best Known Method

    Running an MPI program in symmetric mode on an Intel® Xeon® host and an Intel Xeon Phi™ coprocessor may deadlock in specific cases due to the heterogeneous precision in replicated control flow calculations. The advice is to determine the control flow only on one master MPI process.

    The Issue

    Intel MPI applications can be executed on multiple combinations of Intel Xeon processors and Intel Xeon Phi coprocessors. Four different execution models are supported:
