Hi Geoffrey,
It is perfectly possible to use several GPU in parallel. I believe it
was discussed in the past on the list, but if you want a relatively simple
example you can look at the PyNX library : it was written for X-ray scattering
calculations on large number of atoms, and can either use pyOpenCL or pyCUDA.
It uses python threads to distribute jobs on several GPU.
See http://pynx.sf.net
Most relevant part is the gnu.py file
