The attached document describes some common issues and questions that have been reported and how they might be addressed.
Are you having problems with your hardware (Cannot see your Intel(R) Xeon Phi(tm) coprocessor? Sporadic accessibility?) or with the Intel(R) Manycore Platform Software Stack (Intel(R) MPSS) running reliably?
Attached to this post are PDF "flowcharts" that explain how you can troubleshoot the problem (note: Both Linux and Windows flowcharts are available), and shows what information you will want to collect if you need to escalate your issue to your OEM provider or Intel.
Do you have questions that you are not finding the answers for in our documentation? Need more training, source code examples, on what specifically? Help us understand what's missing so that we can make sure we develop documentation you care about (what is important, and what is nice to have)! Thank you
In the period prior to the launch of Intel® Xeon Phi™ coprocessor, Intel collected questions from developers who had been involved in pilot testing. This document contains some of the most common questions asked. Additional information and Best-Known-Methods for the Intel Xeon Phi coprocessor can be found here.
The Intel® Compiler reference guides can be found at:
- Intel Instruction Set Architecture Extensions
- Intel® Architecture Instruction Set Extensions Programming Reference includes:
- Intel® Advanced Vector Extensions 512 (Intel® AVX-512) instructions (AVX512F, AVX512DQ, AVX512BW, AVX512VL, AVX512CD, AVX512PF, AVX512ER)
- Intel® Secure Hash Algorithm (Intel® SHA) extensions
- Intel® Memory Protection Extensions (Intel® MPX)
As learning purpose, i tried to code a program which find total number prime number for a given range. isprime function finds if a number is prime or not. I added !$omp declare simd to vectorize that function. I do not know why, program perform three times slower in intel phi than host.
Host: 16 sec
MIC: 43 sec
If you use Environment Modules (from Sourceforge, SGI, Cray, etc) to setup and control your shell environment variables, we've created a new article on how to quickly and correctly create a modulefile. The technique is fast and produces a correct modulefile for any Intel Developer Products tool.
