NAMD 2.10 with MVAPICH2-GDR?

I am having some difficulty getting NAMD 2.10 to use all GPU units on an
8-node cluster (2 GPU devices per node) when using MVAPICH2-GDR 2.1a. Is
the use of MVAPICH2-GDR supported? It seems to launch the appropriate
number of CPU processes on all nodes, but only uses 4 GPUS (2 GPUs on 2
separate nodes).

* RHEL 6.x - kernel 2.6.32-358.23.2.el6
* Intel Composer XE 2015
* CUDA 6.5
* Mellanox OFED 2.1

Thanks in advance,
    Dave
