Hi,<br><br>I am using superlu dist in PETSc 3.1. The version of superlu dist installed by petsc is SuperLU_DIST_2.4-hg-v2. Does anyone know which colperm method superlu dist use for the default setting by petsc? I cannot got such information by using -mat_superlu_dist_statprint, the output of which I attached below. Thanks.<br>
