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
