This document provides a general summary of new features and important notes about the Intel® Math Kernel Library (Intel® MKL) software product.
Please see the following links to the online resources and documents for the latest information regarding Intel MKL:
If your MPI program sends messages of drastically different sizes (for example, some 16 byte messages, and some 4 megabyte messages), you want optimum performance at all message sizes. This cannot easily be obtained with a single DAPL* provider. This is due to latency being a major factor for smaller messages, but bandwidth being more important for larger messages, and providers often making a tradeoff to improve one or the other. The Intel® MPI Library, as of Version 4.1 Update 1, now supports up to three providers for a single rank of your job.
