Andreas,
I've tried running in debug mode in Wing, but it appears the crash is being
forced by windows. I don't get a chance to debug as windows forces python.exe
to close.
I was pretty sure I tried building and installing PyCuda from the tarball and
received errors that the Shipped Boost wasn't found (the installer then
proceeded using (USE_SHIPPED_BOOST = False). That's why I ended up compiling
boost myself. But, I may be misremembering.
Where can I find the cuInit function? I can't seem to find it in any of the
PyCuda files...
Thanks!
Mike

It isn't. If you download pycuda 0.94, the code will default to building
with its own small subset of boost that comes in the
tarball. (USE_SHIPPED_BOOST = True)

cuInit()

No idea, sorry. Can you run stuff in a debugger to check?

Exactly like the contents of autoinit, except that you have more
flexibility in picking devices, for example.
