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?

remark: Some OpenMP processing was skipped to constrain compile time. Consider overriding limits (-qoverride-limits)

I am using ICPC 2017

For some applications, I am receiving the remarks as displayed in the title.

 

 

However, the application in question does not even use OpenMP at all. For simplicity I enabled the -qopenmp flag for all executables in the same project. Some of them do use OpenMP. But the program in questions does not. Shall it -qopenmp has no effect, except linking an extra (useless and almost harmless) libiomp when the source does not have any #pragma omp?

icpc-16.0 Update4 does not know std::rbegin() and std::rend()

Hi, the code below can be compiled fine with g++-5.4.0 under Ubuntu-16.04, but not with icpc-16.0 Update4 even if -std=c++14 specified.

% icpc -V

Type deduction failure with a class template explicitly specialised with a user defined type

Type deduction failure with a class template explicitly specialised with a user defined type

Hi,

I am trying to recompile a simulation program using icl to take advantage or Intel's mkl library, however, I have discovered a potential bug with the icl compiler.

I have a class template which is explicitly specialised with a user defined type (a struct of parameters which will be different for different distributions).

I have attached a stripped down version of my code ('get_type.cpp') which reproduces the error.

Linux-4.6+ kernel compilation - compiles but black screen / doesn't boot

Hi,

I decided to have a whirl at compiling the linux kernel (specifically, linux-4.7.3) and while I was able to get the kernel to compile, it doesn't boot and/or I am left with a blank screen/ (no boot console, as one would expect to see)... I can't currently putty/ssh into the machine to see if it is just a blank screen or doesn't boot...
