Have we considered using this

as an alternative sparse matrix-matrix code for GAMG? Or was it unsuitable for some reason.

I don't think we considered it for that purpose. I'm not sure if its dynamicism would work against us here.

I took a look at the code. It is the worst kind of C-in-C++, It would probably take 1 day to make a pure C version :) The claim from Edgar is that it is intended to be used for this purpose (have you read the arXiv thing with Torsten about sparse tensor computing?).
