Get Ready for Intel’s Knights Landing (KNL) – 3 papers

May 11, 2016

2nd generation Intel Xeon Phi processors code-named Knights Landing (KNL) are expected to provide up to 3X higher performance than the 1st generation. With on-board high-bandwidth memory and optional integrated high-speed fabric—plus the availability of socket form-factor — these powerful components will transform the fundamental building block of technical computing. Download three essential publications on new features in Knights Landing Processors: Automatic Vectorization with Intel AVX-512 Instructions in KNL In this document, we focus on the new vector instruction set introduced in Knights Landing processors, Intel® Advanced Vector Extensions 512 (Intel® AVX-512). The discussion includes: Introduction to vector instructions in general, The structure and specifics of AVX-512, and Practical usage tips: checking if a processor has support for various features, compilation process and compiler arguments, pros and cons of explicit and automatic vectorization, using the Intel® C++ Compiler and the GNU Compiler Collection.

Slide Deck for Colfax Developer Training on Parallel Programming

February 26, 2016

We are making publicly available the slide deck of the Colfax developer training titled “Parallel Programming and Optimization with Intel Architecture“. This training is an intensive course for developers wishing to leverage the Intel architecture. It is also useful for many-core and multi-core processor programming. The course is based on a book of the same name, which contains targeted exercises (“labs”) for hands-on practicum. In 2014-2015, “Parallel Programming and Optimization…” has visited over 100 locations across the United States: research institutions, government labs, universities, and regional trainings. Over 2000 students attended the course. Many of these events were free to attendees thanks to Intel’s sponsorship. Update: now with new information about the upcoming 2nd generation Intel Xeon Phi processor (Knights Landing, KNL). Slide deck:  Colfax-Developer-Training.pdf (13 MB) (last updated August [...]

Interview with James Reinders: future of Intel MIC architecture, parallel programming, education

March 5, 2015

A few weeks ago we recorded our conversation with James Reinders, the Director and Chief Evangelist at Intel Corporation. We discussed the future of the parallel programming and Intel MIC architecture products: Intel Xeon Phi coprocessors, Knights Landing (KNL), and future 3rd generation – Knight Hill (KNH). We also talked about how students can learn parallel programming and optimization for high performance applications. Watch the whole interview by clicking the player above, or jump straight to one of the questions in the list below. James Reinders and his role at Intel. – 00:47 Why Parallel Programming and Code Modernization is important? – 01:49 Brief introduction to MIC architecture and Xeon Phi coprocessors. – 04:03 What type of applications benefit from MIC architecture? – 07:16 How to approach porting your code for MIC architecture? – 09:58 What is new in Knights Landing. – 15:24 Details of chip design of Knights Landing. – 19:54 3rd MIC generation – Knights Hill. – 21:16 How to future-proof my code? – 23:15 [...]
