A parallel algorithm for large sparse symbolic and numeric Cholesky facto rization on a multiprocessor:
We develop an algorithm for computing the symbolic and numeric Cholesky factorization of a large sparse symmetric positive definite matrix. The algorithm is intended for a message-passing multiprocessor system, such as the hypercube, and is based on the concept of elimination forests. In addition, w...

| Zusammenfassung: | We develop an algorithm for computing the symbolic and numeric Cholesky factorization of a large sparse symmetric positive definite matrix. The algorithm is intended for a message-passing multiprocessor system, such as the hypercube, and is based on the concept of elimination forests. In addition, we provide an algorithm for computing these forests along with a discussion of the algorithm's complexity and a proof of its correctness. We also examine the related issue of load balancing. |
