Hi Peter I just had the same problem last week: http://pycuda.2962900.n2.nabble.com/PyCUDA-test-driver-py-problem-td5276874.html#a5276874
Updating to the latest git commit will solve your context-related issues, due to Fermi architecture not accepting unaligned accesses (thanks again Andreas for the fix !). Beside, try the examples (obtained via examples/download-examples-from-wiki), most of them should work, even with the 0.94rc instead of the GIT version. However, the precision issues remain.
