Edit Question
Title
Body
I have seen that Intel seems to have included a new assembly function to get real random numbers obtained from hardware. The name of the instruction is RdRand , but only a small amount of details seem accessible on it on Internet: http://en.wikipedia.org/wiki/RdRand My questions concerning this new instruction and its use in C++11 are the following: Are the random numbers generated with RdRand really random? (each bit generated from uncorrelated white noise or quantum processes? ) Is it a special feature of Ivy Bridge processors and will Intel continue to implement this function in the next generation of cpu? How to use it through C++11? Maybe with std::random_device but do compilers already call RdRand if the instruction is available? How to check whether RdRand is really called when I compile a program?
