In this paper, we present a methodology for mapping an Embedded Signal Processing ESP application onto HPC platforms such that the throughput performance is maximized. Previous approaches used a linear pipelined execution model which restrict the mapping choices. We show that the optimal" solution obtained under that model can be improved, using the(More)
In irregular all-to-all communication, messages are exchanged between every pair of processors. The message sizes vary from processor to processor and are known only at run time. This is a fundamental communication primitive in parallelizing irregularly structured scientific computations. Our algorithm reduces the total number of message start-ups. It also(More)
Recently, High Performance Computing (HPC) platforms have been employed to realize many computationally demanding applications in signal and image processing. These applications require real-time performance constraints to be met. These constraints include latency as well as throughput. In order to meet these performance requirements, eecient parallel(More)
