"Error launching CUDA compiler: 256" on OpenMM context creation

See original GitHub issue

Keep having this error on the cluster running with nodes=2:ppn=4:gpus=4:shared. The exception is raised after the solvent phase has been completed, during resuming of the complex phase. I’m looking into this.

Some additional testing notes:

This might actually be an MPI version problem. We are using mpich2-1.4.1p1 (not sure which package installs it). However, mpich2 got to version 1.5-ish then changed back in November 2012 the versioning to just mpich starting at 3.0. There is now a 3.2 on conda-forge and it appears to not have this problem on the simple test. I will test with YANK itself first to see if that really is the problem.

This should be fixed as #686, we can re-open if it crops up again
