The Intel® Xeon Phi™ User's Group (IXPUG) is an independent users group whose mission is to provide a forum for the free exchange of information that enhances the usability and efficiency of scientific and technical applications running on large High Performance Computing (HPC) systems using the Intel® Xeon Phi™ processor. IXPUG is administered by representatives of member sites that operate large Phi-based HPC systems.

IXPUG holds meetings and other activities as determined by its members to further its mission. Participants include staff from member sites, users of member sites’ facilities, Intel staff, and others with an interest in using the Intel® Xeon Phi™ for scientific computing on large HPC systems.

Participation in IXPUG meetings and other activities is open to anyone interested in using the Phi for large-scale scientific or technical computing.

A Steering Committee manages the overall direction of IXPUG, planning meetings and activities and working with members and sponsors to determine the most effective way to serve the HPC community.

What is IXPUG?

  • IXPUG is a community-driven organization that fosters technical collaboration around tuning for the Intel® Xeon Phi™ [Co-]processor family.
  • IXPUG stands for Intel® Xeon Phi™ Users Group

How did it get started?

  • The original vision for IXPUG was that “exceptional success” for the Xeon Phi program requires more than a 1-way communication between Intel and HPC center and application scientists; it involves building a community that develops and shares tribal knowledge on how to transform, parallelize, and optimize code to make the most of Xeon Phi.
  • Over a period of years, Intel and the HPC community have worked together to create and share technical collateral, training, workshops to share proof points and challenges, and to forge a way forward together.
  • In 2014, the Texas Advanced Computing Center hosted a highly successful IXPUG meeting and the excitement and enthusiasm from that meeting have carried over to a number of ensuing events. 

How does IXPUG relate to Intel?

  • IXPUG has independence from Intel, but it benefits from Intel’s support, especially its technical investment.

How does IXPUG relate to other ‘code modernization efforts?’

  •  IXPUG is one of many ways of supporting the broader community’s code modernization efforts.  Those efforts stem from Intel, application readiness efforts at the U.S. Department of Energy national labs, and numerous similar efforts in academia and at HPC centers world-wide.

Who is part of IXPUG?

  • Anyone interested in achieving performance on codes running on the Intel Xeon Phi is welcome to be part of IXPUG. IXPUG's focus is on High Performance Computing applications in science and engineer, but it is not limited to those ares.
  • IXPUG is governed and led by an leadership board and steering committee. IXPUG also has organizational members, who are committed to providing resources to help support IXPUG (staff time, hosting meetings, etc.)
  • Participants in IXPUG primarily come from industry, academia, national labs and institutes, and HPC centers from around the world.
  • Intel contributes heavily to IXPUG through participation from its technical staff and Intel also helps defray costs associated with IXPUG activities.
  • If you would like to participate, please see the "Join IXPUG" link on the IXPUG web site (http://ixpug.org/) (Link will be available soon.)

What does IXPUG do?

  • IXPUG brings together experts and practitioners as a community, in events at major HPC-related conferences, standalone workshops, active technical working groups, and shares learnings through ixpug.org and other related sites.
