USE OF HIGH-LEVEL BASIC LINEAR ALGEBRA SUBPROGRAMS (BLAS) IN VISCOELASTIC FLOW SIMULATIONS

This paper discusses the advantages of using higher level Basic Linear Algebra Subprograms (BLAS) in linear equation solvers. On workstation s with cache memory, the execution time to solve a system of linear eq uations can be reduced by as much as 90% (10-fold speedup) by using Le vel 3 BLAS. The frontal elimination code developed at M.I.T. [1] is mo dified to exploit Level 3 BLAS. The enhanced frontal solver runs at ar ound 550 Mflops on a single processor of a Gray C90, and about 3-4 tim es slower on a 195-MHz SGI Power Challenge. (C) 1998 Elsevier Science B.V.
