Sometimes when we do not have exact counts, we need to overestimate sizes. This is especially true in sparse MatMat.
Ok... so, to be sure, I am correct if I say that recompiling petsc with "--with-64-bit-indices" is the only solution to my problem?I mean, no other fixes exist for this overestimation in a more recent release of petsc, like putting the result in a "long int" instead?
Thanks, Eric
