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)
Kahaner, Experiments with an ordinary differential equation solver in the parallel solution of method of lines problems on a shared-memory parallel computer, Journal of Computational and Applied Mathematics 38 (1991) 231-253. We consider method of lines solutions of partial differential equations on shared-memory parallel computers. Solutions using the(More)
Wide Issue super scalar processors are very complex machines. Simplescalar toolset makes the job of selected parameter simulation for such processors a lot easier. The use of critical quantitative analysis based upon the SimpleScalar simulations augmented with a qualitative analysis for a rational cost/performance model is necessary to select optimal(More)
