Hello all, just getting started in CUDA and I had a quick question.
Can a grid (of thread blocks) be three dimensional (where z > 1)?
The programming guide states:
“To help with complex addressing based on the block ID, an application can
specify a grid as a two-dimensional array of arbitrary size…”
This would seem to imply that a grid of blocks is intrinsically a 2D structure.
However, much (all) of the data I work with is large and 3-space native so for
several reasons I would prefer not to squash everything down to 2D
addressing and then transfer back (i.e. the ol’ fragment program paradigm).
Thanks for your time and help,
