Abstract

A unique decomposition model using two-task replacement sets is used to model algorithm decomposition and algorithm performance. This technique provides a parametric representation of decomposition and performance analysis that is more general and powerful than previous methods. The model is used to investigate the performance of algorithms for MIMD architectures, and the results include statistical descriptions of task and synchronization penalty behavior under decomposition and analytical representations of algorithm performance. The analysis provides insight into the effect of decomposition on performance at both the local task and global algorithm levels. This information would be useful to those interested in compiler technology or algorithm development tools.
