KMP_PLACE_THREADS

new KMP_PLACE_THREADS OpenMP affinity variable in Update 2 compiler

Are you using OpenMP with the Intel Composer XE 2013 Update 2 for Intel(R) Xeon Phi Coprocessors?

Did you know there is a new environment variable to control thread affinity and topology on Phi in the Composer XE 2013 Update 2 compiler (13.1.0.146)? It was in the Release Notes for Composer XE 2013 Update 2, so surely you read it there. :)

If you did hear about KMP_PLACE_THREADS, also keep in mind IT DOES NOT REPLACE KMP_AFFINITY, rather, it WORKS WITH KMP_AFFINITY.
