Best implementations of core.matrix for MBPro M1/arm machines?

[Richard Belew]

I've got a new MacbookPro with the M1Pro chip, and now in the process of porting various code bases. 

I had been using uncomplicate.neanderthal on my Intel+CUDA machines, and just reviewed the interesting discussion

https://groups.google.com/g/clojure/c/WxwDe8uLzdM)

(from 2016) about how/why it and core.matrix diverged.

I'm looking for recommendations as to which libraries/implementations are working best on the new M1 machines?  My primary interest is in spectral graph analysis, so functions like eigen, svd, etc. are of most interest.

Thanks for any pointers,  Rik
