Detailed Description

Multifrontal direct solver (METHOD=DIRECTmf): LDLt with threshold pivoting for symmetric (possibly indefinite) matrices, LU for structurally symmetric matrices with unsymmetric values. Multi-process runs hold the global matrix partially per rank, run the symbolic stage on rank 0 and distribute the numeric stage subtree-to-subcube.

Compare the elimination tree and the column counts with the symbolic stage of the built-in direct solver, on the same node graph and the same permutation. Both trees are compared in the original node labels since the two codes postorder differently.
