Data movement is a critical bottleneck for futuregenerations of parallel systems. The class of .5Dcommunication-avoiding algorithms were developed to addressthis bottleneck. These algorithms reduce communication andprovide strong scaling in both time and energy. As a firststep towards automating the development of communication-avoidinglibraries, we developed the Maunam compiler. Maunam generates...
The need to parallelise desktop applications is becoming increasingly essential with the mainstream adoption of multi-cores. In object-oriented languages, sequential iterators handle iterative computations of a sequential program; similarly, the parallel iterator was developed to handle the iterative computations of a parallel program. This paper presents the progress of the parallel iterator concept...
The current trend is for processors to deliver dramatic improvements in parallel performance while only modestly improving serial performance. Parallel performance is harvested through vector/SIMD instructions as well as multithreading (through both multithreaded cores and chip multiprocessors). Vector parallelism can be more efficiently supported than multithreading, but is often harder for software...
