[infomap-nlp-users] spare matrix format

[<lei...@gm...>]

Hi!

Infomap is now using ordinary C-matrices with 4 bytes per cell. Has
anyone tried to rewrite the matrix handling code using a spare matrix
format like for example Harwell-Boeing? This would make it possible to
run on a much larger vocabulary and also, not limiting the matrix size
in the second dimension.

I would like to run it on 500 million running words or so, which leads
to 3.5 million word types...

What do you developers think? How big would that task be?

Regards,

Leif
