My code to do this is as follows:

1) Put INLINE pragmas on all the leaf functions, especially ‘kernel’. If the compiler does not inline these functions they won’t fuse. This is a key problem with the Repa approach to fusion. 2) The ‘dimensional’ packages wraps a data type around all those values. I’m not convinced the simplifier will be able to undo the wrapping / unwrapping. You’ll need to inspect the core code to check. Ben.
