Subject: Re: [OMPI users] quadrics support?

So, first run i seem to have run into a bit of an issue. All the
Quadrics modules are compiled and loaded. I can ping between nodes
over the quadrics interfaces. But when i try to run one of the hello
mpi example from openmpi, i get:

first run, the process hung - killed with ctl-c
though it doesnt seem to actually die and kill -9 doesn't work

second run, the process fails with
  failed elan4_attach <snipped> Device or resource busy
  elan_allocSleepDesc <snipped> Failed to allocate IRQ cookie 2a: 22
Invalid argument
all subsequent runs fail the same way and i have to reboot the box to
get the processes to go away

I'm not sure if this is a quadrics or openmpi issue at this point, but
i figured since there are quadrics people on the list its a good place
to start
