  abstract = {Traditional pivoting during parallel, unsymmetric $LU$
                  factorization introduces heavy communication and
                  restructuring costs. Possible alternatives include
                  pre-pivoting to place heavy elements along the
                  diagonal and limited pivoting that maintains the
                  factors' structures. Each alternative comes with
                  trade-offs that affect accuracy and performance.},
