OpenMP Run-time Libraries Changed since Intel IPP 6.0 and Intel MKL 10.1
This document describes changes for OpenMP support since Intel IPP 6.0 and Intel MKL 10.1.
High CPU usage and Intel® IPP threaded function
The article describes serveral possible scenarios and solution for high cpu usage when call IPP function in real application
Where are my threads? - Part II
In my previous article, “Where are my threads?”, I briefly described the usage models for the Sample Over Time (SOT) feature of Intel® VTune™ Performance Analyzer. I also explained how VTune analyzer can help to break down the events sampled per core/processors. One of the key benefits of SOT that I highlighted is how it can help detect scheduling issues. In this article, I will explain this benefit in more detail.
Control OpenMP thread affinity with ippSetAffinity function
set the threading affinity with ippSetAffinity
Don't use the OpenMP THREADPRIVATE 'compatibility' option when everything is compiled by Intel
The Intel C++ and Fortran compilers for Windows* and Linux* provide 'legacy' and 'compatibility' implementations of the OpenMP THREADPRIVATE directive. The 'compatibility' option should not be used when everything is compiled by Intel compilers.
Параллельное программирование - OpenMP. Эксперименты: часть 1
Всегда думал, что параллельное программирование это очень сложно…
Несколько дней назад услышал про OpenMP, до этого мой опыт параллельной разработки заключался в написании нескольких простых приложений для windows. И, честно сказать, от методов распараллеливания я был не в восторге…
Первый код с OpenMP, который я увидел:
Beginning Hybrid MPI/OpenMP Development
A guide for getting started combining MPI and OpenMP in one program. Code samples are included.
Memory Leak when Using Intel® MKL
The article show several memory leak issues when using Intel MKL and gives some solutions.
Artificial Neural Nets and Hyper-Threading Technology
by Chuck Desylva
Introduction
Different methods for optimizing AI algorithms to take advantage of an Intel® Pentium® 4 Processor with Hyper-Threading Technology
The purpose of this paper is to highlight several key artificial intelligence (AI) software technologies and some simple changes that can be made to them to gain performance improvements on the Pentium® 4 and Intel® Xeon® processors.
