Dear pyCUDA users,
I have the above NVIDIA cards installed in my workstation. The FX 580
passes test_driver.py, test_math.py, and has 5 assertion errors on
test_gpuarry.py.
The GTX 480 card failes test_driver.py, but passes test_math.py, and has
4 assertion errors on test_gpuarray.py. The test_driver.py fails with
the attached message. Does anyone know what is causing GTX 480 to fail
this test, and not FX 580?
I'm using Ensight Python Dist 6.2.2, boost 1.44, pyCUDA-0.94rc, CUDA 3.1
and CUDA drivers version 256.40.
Thank you for your help,
Brani

-------------------------------------------------------------------
PyCUDA ERROR: The context stack was not empty upon module cleanup.
-------------------------------------------------------------------
A context was still active when the context stack was being
cleaned up. At this point in our execution, CUDA may already
have been deinitialized, so there is no way we can finish
cleanly. The program will be aborted now.
Use Context.pop() to avoid this problem.
