The NIST Sparse BLAS (v. 0.9)

Performance Studies on the SUN Sparc 20

Sparse BLAS Homepage





The test matrices used in the following tests were generated by reading sparsity patterns from Harwell-Boeing files, and using these patterns as the block structure for a matrix of given blocksize. The results shown are for Matrix-Vector and Matrix-Matrix multiplications only, rather than a full DAXPY, since we are interested in the efficiency of the sparse code. Source code for the performance testers is available from the authors.

The current test results are for the following matrix patterns: The experimental parameters are blocksize and number of right-hand-sides. We present results of testing on a Sun Sparc 20 and an IBM RS6000. Each data point represents the average result of 4 runs with the same parameters.
