I'm having issues getting pycuda to run properly. I had issues installing,
which I suspect is the root of my issue now. Following these instructions: 

http://wiki.tiker.net/PyCuda/Installation/Linux/Ubuntu

I had to remove the last configuration flag --no-use-shipped-boost, because
it said there was no such argument. Also, I'm not using python3, so I
changed all references to python.

Doing that, I got it to install. I can import all of the tools, but when I
try to get to the SourceModule reference in demo.py, I get the following
error:

Traceback (most recent call last):
  File "hello_gpu.py", line 14, in <module>
    """)
  File

  File

[stderr:

If I change the shader model to a smaller value, e.g. sm_21, I get the
following error:

>>> mod = SourceModule(
... """
... __global__ void multiply_them(float *dest, float *a, float *b)
... {
...   const int i = threadIdx.x;
...   dest[i] = a[i] * b[i];
... }
... """,arch="sm_21")

line 265, in __init__
    self.module = module_from_buffer(cubin)
pycuda._driver.LogicError: cuModuleLoadDataEx failed: invalid source - 

Can someone point me to a resource to fix this?

Thanks.
