What is the default_random_engine for Intel Compiler in std::random

[B___Christoph]

And secondly, where is this documented? I think gcc's standard is a Mersenne Twister, but what is the standard for icpc?

Thank you for your response,

icpc is compatible with gcc. So, it would be the same standard as GCC's.

Hello Viet Hoang,

So default_random_engine is mt19937? Is that what you are saying? I am asking because from our tests, it seems it is not. The coherence length seems to be a lot smaller.

This is part of the C++ standard library which Intel doesn’t supply. The Intel linker just links in the library on the system. I am not sure why you got a smaller coherence length.
