A comparison of two effective methods for reordering columns within supernodes
M. Ozan Karsavuran, Esmond G. Ng, Barry W. Peyton
In some recent papers, researchers have found two very good methods for reordering columns within supernodes in sparse Cholesky factors; these reorderings can be very useful for ce…

Some new techniques to use in serial sparse Cholesky factorization algorithms
M. Ozan Karsavuran, Esmond G. Ng, Barry W. Peyton +1
We present a new variant of serial right-looking supernodal sparse Cholesky factorization (RL). Our comparison of RL with the multifrontal method confirms that RL is simpler, sligh…
