Question

I tried to implement “Monte Carlo” algorithm in parallel manner, so I need to use a thread safe version of a random number generator.
I searched a lot and finally found
int qrand ()
which is a Thread-safe version of the standard C++ rand() function, (defined in <cstdlib> and <stdlib.h>). When I use it, VS fired “identifier not found” error.

I use MS visual studio’10 and wrote my code in C++ using OMP.

Any help?

boost::random has a number of generators which are objects. The
simplest solution would be to simply use a distinct generator for each
thread.
