Block-Oriented, Local-Memory Linear Equation Solution on the CRAY-2. Part 1. Uniprocessor Algorithms

Experience with the CRAY-2 on the effects of common memory speed and loading on performance indicate that local-memory-based algorithms have potentially a large advantage. The performance of a number of common- and local-memory algorithms are compared for the LU factorization of a dense systems of e...

Zusammenfassung:Experience with the CRAY-2 on the effects of common memory speed and loading on performance indicate that local-memory-based algorithms have potentially a large advantage. The performance of a number of common- and local-memory algorithms are compared for the LU factorization of a dense systems of equations on the CRAY-2. Results of both Fortran and assembly language implementations are given. (Author) Presented at the SIAM Conference on Scientific & Parallel Computing (2nd) Held at Norfolk, VA on 18 Nov 85.
