OpenMP* 4.0 Features in Intel C++ Composer XE 2013

The current OpenMP* 4.0 RC1 specification and associated TR1 technical report (both available from http://openmp.org) adds new features for controlling vectorization and execution on coprocessors. Intel® C++ Composer XE 2013 Update 2 (compiler version 13.1) supports two of these new features regarding the simd and target clauses. These are similar to existing Intel-specific compiler directives.

    • MKL VSL example for grouppooledcovariance (vsldgrouppooledcovariance.f) failed with PGI threading layer.

    Problem Description:

    Grouppooledcovariance example crashs with segmentation fault with PGI threading layer on all platforms due to error in PGI support of OpenMP order clause.

    We can see this example “vsldgrouppooledcovariance.f” into the following directory MKL_ROOT>\examples\vslf\source\". This example shows how to calculates of group/poopled covariances.

    • Free Intel C++ Compilers for Students, and related parallel programming tools.

    I came across this offer - and thought it worth passing along...

    Students at degree-granting institutions are eligible for free Intel C++ tools (and discounts on Fortran tools.)

    Linux, Windows and Mac OS versions available.

    По счастливой случайности мне представилась возможность лично встретить Джона Густавсона, во время его посещени Остина в 2009 году. Заметка ниже -- некоторые мои мысли, возникшие после общения с ним.
