In this paper we used detailed simulations of application kernels to show that memory contention can substantially degrade the performance of SPMD computations on large-scale shared-memory multiprocessors. We showed that under row-major allocation, memory contention is due to synchronized access to entire rows of a matrix, rather than simultaneous accesses(More)
Methodologies are presented for decomposing algorithms on a classical multiprocessor. The class of algorithms considered are those that can be represented as data flow graphs without decision elements. Two passive sonar signal processing modes are used as detailed examples. Decompositions are performed by modeling data memory bandwidth and data memory(More)
