Inconsistent program behavior on RHEL* 7.4 or Fedora* 25 if compiled with Intel Compiler

Hello,

We've seen some reports with regarding to RHEL7.4 OS and Fedora 25 that comes with glibc that has a change that Intel Compiler doesn't work well with. There're simple workarounds for the problem. Please see the following two KB articles for details.

Abstract: Modern generation of Intel(R) Processors come with multiple processing cores and each core offering SIMD registers. This makes it all the more important for Application Developers to be aware of how to utilize all the processing cores efficiently. This webinar will walk step by step on the following concepts using a simple Edge Detection application:

Intel® C++ Compiler 18.0 has been released as part of Intel Parallel Studio XE 2018

Intel® Parallel Studio XE 2018, including Intel® C++ Compiler 18.0, is now available from the Intel Registration Center. Release notes can be found https://software.intel.com/en-us/articles/intel-c-compiler-180-release-notes.

Some of the new supported features are below:

Оптимизировали, оптимизировали, да не выоптимизировали!

Оптимизация? Конечно, каждый сталкивался с данной задачей при разработке своих, сколь-нибудь значительных, требующих определённых вычислений, приложений. При этом способов оптимизировать код существует огромное множество, и, как следствие, различных путей сделать это в автоматическом режиме с помощью опций компилятора. Вот здесь и возникает проблема – как выбрать то, что нужно нам и не запутаться?

__builtin_shuffle, GCC compatibility, and __has_builtin

I recently tried to build one of my projects (SIMDe) with ICC, and it failed due to __builtin_shuffle not being supported. There are ifdefs around the code in question which use __GNUC__ and __GNUC_MINOR__ to check for GCC ≥ 4.7 before using __builtin_shuffle, but ICC 18.0 masquerades as GCC 7 so the code was enabled.
