The readme provides Throughput numbers, but I'm wondering what is the dataset size used.
Typically I would assume that throughput is higher for small sets and lower for larger datasets due to caching and such, so it's useful to provide this number.
I recently moved to a Mac with M2 Max processor and building the project fails due to missing header file (see below). I was curious if there was a parallel version of RecSplit that does not depend on x86-specific instructions? (It wasn't clear to me from the code.)
