The specific tip here is that on Linux, you want to use the openib
BTL, not the udapl BTL. Specifying "--mca btl openib,sm,self" means
that Open MPI will use those 3 BTLs instead of attempting to auto-
select (apparently the auto-selection will include udapl).
Since you never want to use udapl on Linux, it's safe to entirely
remove it from the system:
Then you won't need to include "--mca btl openib,sm,self" on the
command line any more.
