KNL Access and Reporting of KNL Results

Please check out how to get access to KNLs

  • Software Developer Platforms available for purchase - see on the resources page of ixpug.org.  Click here for a 1-page summary.

  • Limited time on a remote KNL.  Please complete the form by clicking here.  Compute time of 4 hours or less, and work for submissions to ISC will be given higher priority.  Once an access decision is made, you'll be notified by email.  You will need an NDA in place to be granted access.

We'll help you get your results data reviewed by Intel for any public release before ISC. You may collect and share KNL data at ISC. You are allowed to submit NDA data to EasyChair without additional review.


TACC KNL Tutorial 

Date: June 19, 2016

Time: 8:00am – 12:00pm

Location: Frankfurt Hotel Marriott (Hamburger Allee 2 Frankfurt Hessen 60486 Germany)

Registration: See https://portal.tacc.utexas.edu/training/#/session/27

The Texas Advanced Computing Center (TACC) at the University of Texas at Austin, in partnership with Intel Corporation, is proud to  announce a special tutorial event as part of the Intel eXtreme Performance Users Group (IXPUG) Meeting at ISC16 in Frankfurt, Germany. This event will provide hands-on experience on the latest Intel product, the second generation Intel Xeon Phi, also known as Knights Landing (KNL). Attendees to this half-day event will be some of the first researchers in the world to have access to the KNL platform.

Hands-on exercises will be executed on the Stampede system at TACC. Stampede has been updated with KNL processors, which will be made available to the general public later this year.

This tutorial will focus on the use of reports and directives to improve vectorization and the implementation of proper memory access, and showcase new Intel VTune Amplifier XE capabilities that allow for in-depth memory access analysis and hybrid code profiling.

The first forty registered attendees through the door will also receive a copy of the new book: Intel® Xeon Phi Processor High Performance Programming, Knights Landing Edition, by Jim Jeffers, James Reinders, and Avinash Sodani.

**NOTE: This training is being offered at the Frankfurt Marriott, rather than at the ISC Conference Location.**
