Hi, I'm still having problems with OpenMP and the x86_64 MinGW compilers - code which can run fine on Linux with any number of threads (mapped to different cores) still will only use one core on an i5 quad core windows box. Is this a windows limitation or a compiler one? Compile with: x86_64-w64-mingw32-gfortran.exe -o a.exe -mno-cygwin -static -O3 -fopenmp -cpp -Domp $(SOURCES) -L/home/Nick/lib/ -llapack -lblas Nick -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
