Dynamic parallelism

1

I am trying to set up a dynamic kernel wherein a KA kernel launches a CUDA kernel. The final objective would be to have dynamic parallelism using only kernel abstractions....

Int32 can be quite a bit faster and we should make sure that we use it where we can for our index calculations.

Variable scoping issue leading to unexpected UndefVarError on CPU

6

I have encountered what I think is a variable scoping issue that causes one of my KernelAbstractions kernels to fail when executing on the CPU. (GPU execution is fine.) I'm...

Attempt at including offsets in kernel launch

5

This PR tries to include offsets in kernel launches so that the `Global` indices returned by `@index(Global, NTuple)` and `@index(Global, Linear)` are offset by an `offset` argument. Example: ```julia julia>...

#382 added EnzymeRules support, but not yet full support for reverse mode on all backends. Currently only CPU is supported for reverse mode.
