[mvapich-discuss] Query related to running MVAPICH over OFED

[yogeshwar sonawane]

Yes, the uDAPL-level tests with OFED 1.1-uDAPL installation are working fine.
I am able to create EPs, transfer data, etc.
But with MPI, i am getting this error.

I am using MVAPICH2-0.9.8p2 with OpenIB-cma as uDAPL provider name.
I have OFED1.1 installed.
