Intel® MKL 10.2 Fixes List

The tables below summarize specific customer issues or feature requests that have been addressed by the indicated product releases.  Some items span multiple architectures and/or operating systems and some relate only to a single architecture or operating system.

NOTE: The issues, defects, bug reports, and feature requests described below represent specific issues with specific test cases.  An item listed here does not imply that it necessarily applies to your application(s).  If your situation does not match the specific test case you may not have experienced the error or problem associated with that update.  It is not possible to describe the details of every issue and its specific test case in these tables.

Providing a complete description of each item in the list below is impractical. For that reason we ask that you post a message on the Intel MKL user forum, /en-us/forums/intel-math-kernel-library/, and reference this page and the "DPD" number associated with the item of interest, if you have questions regarding the information in these tables.

These tables are updated regularly to correct any errors and omissions.
