Hi We've been testing the -fopenmp feature of G++ in Cygwin. We can't get the CPU cores to go to 100% when compiling with the GCC version of G++. If we compile with the MinGW version, the CPUs go to 100%. I've tried several versions of GCC. I started with recent 5.4 version and worked back to 4.8.2. None of the versions will run 100%. In Linux the same code works correctly, going 100% CPU in the parallel sections of the code. Is there something I'm missing in the Cygwin that prevents -fopenmp from running 100% across all the CPUs? Please, any assistance would be greatly appreciated.
