[PyCUDA] CUDA driver compute mode

[Kambiz Tavabi]

Following TB from test_driver.py with 2016.1.2 build on OS X 10.11 with
CUDA 8 V8.0.61; was able to workaround by changing

if drv.Context.get_device().compute_mode == drv.compute_mode.*EXCLUSIVE*:

to

if drv.Context.get_device().compute_mode == drv.compute_mode.
*EXCLUSIVE_PROCESS*:

in test_dirver.py

Is this expected?

Fixed in git, but not yet released:

https://github.com/inducer/pycuda/commit/255644ad802a20191e31bc15f4fd46e6c9d6e38a

Thanks for the report,
