while i wait spinning up support with allinea, i wonder if anyone here does any DDT debugging with mpi+cuda programs?
when i try to debug even a non-mpi cuda program, i can't seem to get ddt to attach to the gpu and then step through the code. when i run the code, it seems to hold on the first call cudaSetDevice, and the "GPU Devices" tab on the right side never shows a device attached. clearly i'm doing something wrong. it's also not unimaginable that i've configured the box in such a way that ddt can't do what it needs to, but i don't get any errors anywhere. any thoughts? _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
