Introduction

This chapter provides a few guidelines for making best use of the performance benefits offered by Sun S3L. The range of topics covered include

• Sun S3L functions that benefit from cyclic distribution

• Sun S3L functions that benefit from distributing only the last axis

• Using shared memory

• Performance guidelines specific to FFT routines

• Performance guidelines specific to dense SVD routines

• Performance guidelines specific to dense linear system solvers

• Performance guidelines specific to banded solvers

• Performance guidelines specific to sparse linear systems solvers

• Performance guidelines specific to dense matrix operations

• Support for convolution, deconvolution, correlation, and autocorrelation
