Abstract
In this paper, we discuss a more scalable OOC implementation of a dense linear system solver via LU factorization that presents numerical stability similar to that of the LU factorization with partial pivoting. Our implementation builds on the Formal Linear Algebra Methods Environment (FLAME), the Parallel Linear Algebra Package (PLAPACK), and the Parallel Out-of-Core Linear Algebra Package (POOCLAPACK) infrastructures. Experimental results on an Intel Itanium2 (R) platform demonstrate the high performance of this approach.
