The CUDA-aware support is only available when running with the verbs interface
to Infiniband. It does not work with the PSM interface which is being used in
your installation.
To verify this, you need to disable the us
this:
mpirun -mca pml ob1 .
This will force the use of the verbs support layer (openib) with the CUDA-aware
support.

Dear Rolf,
thank for looking into this.
Here is the complete backtrace for execution using 2 GPUs on the same node:
(cuda-gdb) bt
#0 0x7711d885 in raise () from /lib64/libc.so.6
#1 0x7711f065 in abort () from /lib64/libc.so.6
#2 0x70387b8d in psmi_errhandler_psm (ep=,
Let me try this out and see what happens for me. But yes, please go ahead and
send me the complete backtrace.
Rolf
