Given a BoundKernel, give me a hash that can be cheaply applied to new inputs to tell whether this BoundKernel is valid

[Chillee]

If you precompile the kernel, you don't want to be in a situation where it's very difficult to tell whether the precompiled kernel is valid for a new shape. For example, user provided hl.specialize calls, int64 indexing choices, etc. It's very hard to do generically without knowledge of the kernel itself.

Does kernel.specialization_key not help with this?

Does kernel.specialization_key not help with this?

we chatted about this -- he also wants to tell whether the compiled kernel would work for int64 indexing as well, not just whether the setting is identical, but also for dynamic shapes etc

[jansel]

specialization_key includes a bit for int64 indexing needed already.

I will try kernel.specialization_key!
