Sorry - been occupied. This is normal behavior. As has been discussed on this
list before, OMPI made a design decision to minimize latency. This means we
aggressively poll for connections. Only thing you can do is tell it to yield
the processor when idle so, if something else is trying to run, w
Should be plenty for us - does your program consume a lot?

Can't offer much about the qsub job. On the first one, what is your limit on
the number of file descriptors? Could be your sys admin has it too low.

Dear MPI users,
using Valgrind I found that the possibile error (which leads to segfault or
hanging) comes from:

Hi,
Are the recent peer to peer capabilities of cuda leveraged by Open MPI
when eg you're running a rank per gpu on the one workstation?
It seems in my testing that I only get in the order of about 1GB/s as
