Zusammenfassung: | Abstract: "This paper explores performance issues for several prominent approaches to parallel dense Cholesky factorization. The primary focus is on issues that arise when blocking techniques are integrated into parallel factorization approaches to improve data reuse in the memory hierarchy. We first consider panel-oriented approaches, where sets of contiguous columns are manipulated as single units. These methods represent natural extensions of the column-oriented methods that have been widely used previously. On machines with memory hierarchies, panel- oriented methods significantly increase the achieved performance over column-oriented methods. |
