Hi all, It seems that attaching two files is not accepted(?). I attach sample code alone to this mail. You can find Makefile in my previous mail.
This very simple sample code hits a possible bug in mingw-w64. I would be grateful if you could test on your system. Best, Takashi ------------------------------------------------------------- Hi All, Finally, I found the minimal condition of my problem. Attached very simple code reproduce the problem. You will get different result(fort.99) at time to time. Essential point is combination of power operation(**) and "omp do schedule(dynamic,chunk-size)". If we have operation ** in a do loop parallelized with schedule(dynamic), result becomes unstable. I don't know fundamental origin of this problem. But, I believe this is unexpected abnormal behavior. As I wrote, my mingw-w64 is a x86_64 package of msys2. I have not tested other versions of mingw-w64 yet. So, I would be grateful if you could test on your system. Any comments and suggestions will be appreciated.
