How it works

We have successfully built an executable for parallel execution on the Windows platform using cross-compilation with a simple toolchain. We were able to specify the number of OpenMP threads by setting OMP_NUM_THREADS. Going from 1 thread to 2 threads, we have observed a reduction of runtime from 2.6 to 1.3 seconds. For a discussion of the toolchain file, please see the previous recipe.
