I have some parallel Fortran90 code in which each thread needs to generate the same sequence of random numbers.
I have a random number generator that seems to be thread-unsafe, since, for a given seed, I’m completely unable to repeat the same results each time I run the program.
I surfed unsuccessfully (almost) the entire web looking for some code of a thread-safe RNG. Could anyone provide me with (the link to) the code of one?
Thanks in advance!
A good Pseudorandom number generator for Fortran90 can be found in the Intel Math Kernel Vector Statistical Library. They are thread safe. Also, why does it need to be threadsafe? If you want each thread to get the same list, instantiate a new PRNG for each thread with the same seed.
