Abstract

To obtain sorting algorithms that scale to the largest available machines, conventional parallel sorting algorithms cannot be used since they either have prohibitive communication volume or prohibitive critical path length for computation. We outline ideas how to combine a number of basic algorithmic techniques which overcome these bottlenecks.
