Excellent! MPI performance should be up as well - JAC is ~21 seconds these days for example...

On Fri, Mar 25, 2011, Scott Le Grand asked about the following errors:

> Error: unspecified launch failure launching kernel kReduceForces
> cudaFree GpuBuffer::Deallocate failed unspecified launch failure

All these seem to have gone away (with both SPDP and DPDP precisions) using
my large-cutoff schemes...thanks!

I have not been testing any MPI runs, so I don't have any comments there.

...regards...dac
