random_openmp

random_openmp a C++ code which uses random numbers during a calculation that has been parallelized with OpenMP.

The random numbers are generated by a function which depends on a user-defined integer called SEED. When multiple OpenMP threads are involved, each thread should be assigned a different initial value for SEED, in order that the threads generate distinct streams of random numbers. This example shows one way that that can be done.
