oh, it is so unfortunate that the first step of my project requires the
inversion of a very large matrix. will have to revert back to scalapack or MR
based solutions I guess.
thanks, canal

I doubt seriously that Samsara will support matrix inversion per se. The
problem is
a) it densifies sparse matrices
b) it is much more costly than solving a linear system
Samsara is roughly memory based, but different back-ends will try to spill
to disk if necessary. It is likely that the resulting degradation in
performance would be dramatic and thus unacceptable to most users.
