This is a good question. When word first came out about using GPUs
for regular computation I sent a message to comp.arch (which is pretty
much a wasteland these days) asking how jobs were going to be
scheduled on a GPU. Nobody knew. I would think this would be
especially important if the same GPU were going to be used
for graphics display and HPC computations. Even if it would only
be used for HPC computations its resources will have to be scheduled
one day. Maybe it could be scheduled as a asymetric MP, which
certain tasks, e.g. the graphics and HPC tasks, having affinity to
the GPU.
