Re-forwarding to OMPI list; because of the OMPI list anti-spam checks, Arlin's post didn't make it through to our list when he originally posted.

I'm forwarding this to the OpenFabrics general list -- as it just came up the other day, we know that Open MPI's UDAPL support works on Solaris, but we have done little/no testing of it on OFED (I personally know almost nothing about UDPAL).

Can the UDAPL OFED wizards shed any light on the error messages that are listed below? In particular, these seem to be worrysome:

 setup_listener Permission denied

 setup_listener Address already in use

These failures are from rdma_cm_bind indicating the port is already bound to this IA address. How are you creating the service point? dat_psp_create or dat_psp_create_any? If it is psp_create_any then you will see some failures until it gets to a free port. That is normal. Just make sure your create call returns DAT_SUCCESS.

 create_qp Address already in use

This is a real problem with the bind, port is already in use. Not sure why this would fail since the current version of OFED uDAPL uses a wildcard port when binding and uses the address from the open; I remember an issue a while back with rdma_cm and wildcard ports. What version of OFED are you using?
