OMP_PROC_BIND is now supported on compatible non-Intel processors

The newest versions of the Intel® C++ and Fortran compilers now support OpenMP* environment variable OMP_PROC_BIND on compatible non-Intel processors for Linux* and Windows* platforms.  The compilers containing the fixes are Intel® Composer XE 2011 Update 13 and Intel® Composer XE 2013 Update 1.  Previous versions of these compilers do not support OMP_PROC_BIND, as defined by the OpenMP* Version 3.1 API specification, on non-Intel processors.  Setting OMP_PROC_BIND={true, false} on a non-Intel processor and running a program linked against the Intel® OpenMP* runtime

  • Gaming Piracy - Separating Fact from Fiction

    I’m sure most of us have all seen and heard the news recently that’s flared up again on Gaming Piracy and DRM issues.   I’d like to address what I feel is one of the most misunderstood, and taken out of context issues that’s plagued this industry for years; and it’s time to put a put a nail in the coffin on this issue.   PC gaming is not being pirated to the tune of 90% by any stretch of the definition.

    Problem: Fortran source files not compiled when building in Visual Studio

    This article provides a solution for the problem of, when in Microsoft Visual Studio, a Fortran source file cannot be compiled (no Compile option when right clicked) or when building a Fortran project, Fortran source files are skipped over. If errors are reported when compiling Fortran sources, this article does not apply.

    First, verify that your Fortran source files have a file type that is recognized by Intel Visual Fortran.  These are:

  • Fortran
  • Intel® Parallel Studio XE Composer Edition

  • HPCC-stream performance loss with the 11.0 and 12.0 compilers

    The STREAM component of the HPCC benchmark suite runs more slowly with the initial release of the 11.0 compiler compared to version 10.1. This can be worked around by disabling function inlining. The COPY component showed a similar issue in 12.0.
