Faster compilation time with Intel(R) C++ Compiler 18.0 Beta

18.0 beta includes several improvements which may result in compile-time reduction for part of your application. In several cases, such a reduction may be significant, and cut compile time by more than 50%. This change is across all optimization levels, and is primarily noticeable for applications with a large number of small functions. While compile time is improved, runtime performance should not be affected. We invite you to try the Intel Fortran and C/C++ compilers 18.0 beta, part of the Parallel Studio XE 2018 beta.

Parallel STL Webinar on May 24th

Hello everyone,

C++17 standard includes implementation of multi-threading and vectorization for STL algorithms (Parallel STL). Intel(R) C++ Compiler 18.0 Beta already has an implementation of this feature and the webinar on May 24th will go over the specifics. You can sign up for the webinar at We will have code samples available after the webinar for folks to evaluate this feature.

Thanks and Regards

Intel C++ Compiler 16.0 is now available in Intel Parallel Studio XE 2016

The new version Intel C++ Compiler 16.0 is now available in Intel Parallel Studio XE 2016 that has launched early this week. If your support license is current you can download and install this at no additional charge from the Intel Registration Center

You will find some blog postings about some new features and new free tools.

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?

Bug Report: icc 18

I recently tried compiling R 3.4.0 from source using the icc 18 ( and found that the resulting program is broken.  This is the script I use to configure and install R:




Getting big endianess byte formatting

I am using the Intel Compiler C++ 16.0 from Parallel Studio XE Composer Edition.
It is integrated inside MS Visual Studio Professional 2013. The OS is Windows 8.
I usually prefer such compiler, in place of the native MS C/C++ compiler.
But recently I had a problem in writing a binary file with "big endianess" of the data.
Such byte ordering in the file is requested by the program which visualizes the data
stored in the file itself (even if it is used on a "little endian" machine). I wrote code using
