This type of error usually occurs when you try to allocate too much memory on the stack. Try allocating your array from the heap. Sent from my phone. No type good. On Sep 18, 2012, at 5:16 PM, "Alidoust" mailto:phymalido...@gmail.com>> wrote: Dear Madam/Sir, I have a serial Fortran code (f9

Segfaults in FORTRAN generally mean either an array is out of bounds, or you can't get the memory you are requesting. Check your array sizes (particularly the ones in subroutines). You can compile with -C, but that only tells you if you exceed an array declaration, not the actual size. It is po

Well, unfortunately it all works fine for me on a Linux x86_64 box. Every command works without issue, though I think my -map-by node -bind-to hwthread doesn't quite generate the pattern I think it should (will have to look more closely at that one). Outside of that, all works fine. I'm not sur
