The GraphBLAS[1] is an amazing API and mathematical framework for building parallel graph algorithms using sparse matrix multiplication in the language of Linear Algebra.

There are Python and and MATLAB bindings, in fact MATLAB 2021a now uses SuiteSparse:GraphBLAS for sparse matrix multiplication (A*B) built-in.

I am working on GraphBLAS-based implementations right now. While the API itself is great, using it full-time I notice documentation is still quite behind and still not too many features. Also there is almost no community outside academia. Crazy efficient though, and very solid overall
