Detailed MPI Analysis

If the quick performance overview for your MPI application is not sufficient, you can use the advanced capabilities of Application Performance Snapshot to get a better understanding of the application flow.
You can break down the analysis results by MPI ranks, functions used, message sizes, and other entities, and filter the results for better readability. There is also support for
MPI_Pcontrol
operation, which allows you to analyze specific code blocks.
See the sections below for detailed information:

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.
