Subject: [OMPI users] SM failure with mixed 32/64-bit procs on the same machine
From: Katz, Jacob (jacob.katz_at_[hidden])

I have two processes, one a 32bit and another a 64bit, running on the same 64bit machine. When running with TCP BTL everything works fine, however with SM BTL it's not.
In one application the processes just got stuck - one in Send and the other in Recv. In another application I even saw a segfault inside the MPI libraries in one of the processes.

Is such scenario officially supported by SM BTL?

Open MPI: 1.3.3
Heterogeneous support: yes
