LaunchConfig parameters

[richardhboyd]

The launch config takes a grid and a block parameter. The block parameter appears to be the number of threads per block. I think this aligns with how the 'regular' annotation works in C++ where you specify <<< number_of_blocks, number_of_threads_per block>>>. When I pass an int to a parameter named block I assume I am telling it how many blocks to use, but I'm actually telling it how 'big' the block should be. If I were creating a block that took an int parameter, I would assume that int is describing how big the block should be.

Does anybody have a mental model that makes this a bit more intuitive? I'm not criticizing the design, I'm just assuming that there's some way of thinking about this that makes the interface feel more intuitive.
