At a low level simplistic way, how about:

[root@tango003 ~]# lsof | grep /dev/infiniband
namd2 7271 weimin mem CHR 231,192 8306 /dev/infiniband/uverbs0
namd2 7271 weimin 13u CHR 231,192 8306 /dev/infiniband/uverbs0
...

Here i can see that the namd that I compiled with openmpi is using IB.

cheers,
