i'm not sure i agree with that or at least my test didn't

on a test machine i can link the CUDA6 lib, but hpcg looks for
libmpi.so.1 and openmpi 1.10.2 provides libmpi.so.12

thinking i might be able to fake it with a symlink, i can satisfy the
lib dependancy, but then hpcg spits out

Cuda error: generate_problem_cuda in file '../src/CudaKernels.cu' in
line 176: invalid device function .
