Hi all,
It is said in CUDA 4.0 programming guide that "Blocks are organized into a
one-dimensional, two-dimensional, or three-dimensional
grid of thread blocks". Does PyCuda currently support 3-dimensional
grid?
Nope, this will happen once PyCUDA switches over to stateless launches
internally, as described in my previous email. CUDA's stateful launch
interface is 2D-grid-only, and PyCUDA uses that internally for greater
backwards compatibility.

New subject: 3-dimensional grid
I was wondering if there was a rough estimate of when / what would
trigger 3d grids being supported in pycuda (is it only formal removal
of the stateful interface in cuda that would cause this to happen?).
We are running into issues where the real solution is to have a Z-grid
1, and I'm trying to determine if implementing a workaround for
only
having 2d grids is worthwhile. Thanks for any info!
Cheers,
Eli
