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?

Using SVML


I am using a single SVML function (___mm256_pow_ps()) among other non-SVML intrinsic functions in my code compiled with icpc. Is the following flag:-fimf-use-svml=true:pow the only one I should be using? I am probably missing something. Is there a different header, in addition to immintrin.h, that should be used? My compilation error is:

error: identifier "__m256_pow_ps" is undefined

Thanks in advance,





Intel C++ Compiler 18.0.0 - aligned_alloc with check-pointers compile error

The Intel C++ Compiler (18.0.0), and the C compiler for that matter, throws an internal compiler error when compiling an aligned_alloc call with -check-pointers.


#include <stdlib.h>

int main() {

double * ptr = (double*)aligned_alloc(32,64*sizeof(double));



When I compile

icpc -check-pointers=rw test.cxx

I get

": internal error: 010101_0


This code compiles fine without check-pointers
