We're basically using the configuration on our pool and it appears to
work fine.  We have a mix of Nividia cards but no ATI, but you're
right an OpenCL or an ugly hack will probably have to be done.  We
don't have any plans to move to ATI so we're okay with it.  We haven't
approached the dynamic slots on our machines even though we have 12
cores/node and 4/gpus.  For our code we typically run 2cores per gpu,
except in conder where we're allocating one slot per gpu.

If you attempt dynamic slots with gpu's i'd like to hear about it.
