Intel® Xeon Phi™

Intel® Xeon Phi™ Coprocessor is the brand name for all Intel® Many Integrated Core Architecture (Intel MIC Architecture) based products. At the end of 2012, Intel launched the first generation of the Intel Xeon Phi product family (coprocessors codenamed "Knights Corner") complementing the existing Intel® Xeon® processor product families to deliver new levels of performance for highly parallel workloads.

This forum is for discussion of public information about Intel MIC Architecture, Intel Xeon Phi Coprocessors, and preparing code to fully utilize this class of machines whether on a single chip or not (this is the key to programming the coprocessor).

Please visit the Developer zone at http://software.intel.com/mic-developer to see all documentation resources available for assessing, configuring, programming, and optimizing for Intel Xeon Phi Coprocessors.

Questions will be answered by both peers and Intel representatives that monitor this forum.

We invite you to subscribe to this forum to see new threads and updates (see button below, on the right). Please also note the ability to search for specific information within this forum, by clicking the button below, on the left.

Intel monitors this forum Monday – Friday, 09:00 – 17:00 Pacific Time (GMT –7:00). Depending on the amount of research we need to do to track down the answer, it may take a day or two for us to respond.
