Hello,
My mpi parallel code has some problem running on our cluster which uses a
Copper Gigabit Switch. My jobs finishes with errors. (One of the processes
started by mpirun has exited with a nonzero exit). However, the same one
runs without problems on the beowulf cluster using Myrinet cards.
- What could possibly be the cause the problem?
- Is it the coding (parallel algorithms)?
- Does it have anything to do with rates of sending and receiving data
across processors? (CPU's speeds have to be equal?)
Thank you and regards,
