ok, but what about -matmatmult_via scalable?
Both should work. It just may be one is faster or slower than the other
depending on the problem size.
ok, digging further, I found this into blaming the code:
0fc8cf34 (Hong Zhang 2013-06-27 14:04:58 -0500 696) /* same as
MatMatMultSymbolic_MPIAIJ_MPIAIJ_nonscalable(), except using LLCondensed
to avoid O(BN) memory requirement */
But the commit comment says:
...
rename MatMatMultSymbolic_MPIAIJ_MPIAIJ ->
MatMatMultSymbolic_MPIAIJ_MPIAIJ_nonscalable (non-default)
But it *is* the default... since another commit:
commit 0d3441ae8a080c728abf17e90308c510e39e951b

add MatPtAPxxx_MPIAIJ_MPIAIJ_new
which changed the behaviour programmed in 0fc8cf34. Is it normal?
