Hybrid MPI + Multicore + Cuda build

I am managing a GPU cluster. The configuration of the nodes is :
- 8 x K20 per node
- 2 x 10-core sockets per node.

The GPUs are run in exclusive process mode to prevent one user to hijack
the GPU allocated to another user.

I would like to be able to run Namd with Cuda, with 1 MPI rank per GPU
and 2 or 3 threads.

Is it possible to build namd with such hybrid support ? All I see on the
website and documentation is either multicore or mpi, but never both.
