About the Intel® Manycore Platform Software Stack

The "Intel® Manycore Platform Software Stack." is necessary to run the Intel® Xeon Phi Coprocessor. Users often call this stack "MPSS" for short. It is dependent on Linux kernels 2.6.34 or later , and it has been tested to work with specific versions of 64-bit Operating Systems:

The readme files (referenced in the Download section) have more information on how to build and install the stack.

The open source updates we have made are in support of the instruction set, the ABI, initializing and controlling an SMP on-a-chip, and the glue software to support the coprocessor communication with the host system. The changes in the Linux kernel are primarily for three reasons:

  • Numerous little changes to support the unique combination of an Intel® Pentium® processor core that also supports 64-bits including the Intel® Initial Many Core Instructions (Intel® IMCI).
  • Power management, which is a feature not associated with the original Pentium processors. Power management is much more important when you have up to 61 cores on a single die
  • The Intel® Many Integrated Core (MIC) check architecture, also a feature not present in the original Pentium processor designs.

The Symmetric Communications InterFace (SCIF) is included in the RPM bundle. SCIF provides a mechanism for inter-node communications within a single platform. A node, for SCIF purposes, is defined as either a Intel® Xeon Phi Coprocessor or the Intel® Xeon® processor. In particular, SCIF abstracts the details of communicating over the PCI Express bus. The SCIF APIs are callable from both user space (uSCIF) and kernel-space (kSCIF).

The MPSS is downloadable from the sources below. Note that these packages include documentation and APIs (e.g. SCIF API).

Please note: the Linux* MPSS download files marked '.gz' should end in '.gz' when downloaded; most browsers leave the extension alone, but Windows Explorer may rename the files. If this affects you, we recommend renaming the file to the proper extension after downloading.

If it is necessary for you to access slightly older releases of the MPSS, please visit the archive at: http://software.intel.com/en-us/articles/intel-manycore-platform-software-stack-mpss-archive

Downloads

There are currently 4 major releases available of the MPSS;  The 2.1 release is an evolution of the MPSS that Intel originally released in November of 2012. And, the most recent major releases are 3.5, 3.4 and 3.3.

We recommend new adopters to start by using the 3.5 release. We recommend existing users who are still using the 2.1 release stream to read this FAQ and migrate to the 3.5 release as soon as feasible for them, to inherit new features and bug fixes as they become available over time. Support for each Intel® MPSS release ends 1 year from the date it was posted.

NOTE: There is an incompatibility between the Intel® MPSS version 3.5 for Windows host and the Intel® Vtune™ Amplifier 2015. If use of this profiling capability is required, we recommend using an earlier version of the Intel® MPSS for Windows host until the issue is resolved – the fix is anticipated to be released in the Intel Vtune Amplifier 2015  in the mid May 2015 timeframe. We will update this note when precise release versions are available.

MPSS 3.3.5 release for Linux

Note: Previous Intel® MPSS 3.X releases provided distribution-branded tarballs (for example: mpss-3.2-rhel-6.4.tar) for the stack, including the user-space rpms. Starting with this release a single distribution-agnostic tarball will be available, which will include kernel-space rpms that are precompiled for specific kernel versions. (As with previous releases, kernel source rpms will be available to support other kernel versions).  The new tarball is called “mpss-3.3-linux.tar”.   Key features of this specific release are described  here

Additional documentation

There is additional documentation in the MPSS packages, more specifically:  man pages and documents in /usr/share/doc/ (see myo, intel-coi* and micmgmt directories).   The  Platform Control Panel User Guide is now in /usr/share/doc/micmgmt/en_US/.

Additionally, there is a document attached at the bottom of this article, the Intel® MPSS Performance Guide, which documents best known methods for fine tuning the Intel® MPSS runtime environment for best application performance.
