Abstract

A probabilistic method is presented to derive the cache performance of irregular applications on machines with direct mapped caches from inspection of the source code. The method has been applied to analyse both a program to multiply a sparse matrix with a dense matrix and a program for the Cholesky-factorisation of a sparse matrix. The resulting predictions are compared with measurements of the respective programs.
