ISx: A Scalable Integer Sort for Co-design in the Exascale Era

This paper introduces a new scalable integer sort application inspired by the NAS Parallel Benchmark integer sort. We provide a detailed analysis of the NPB integer sort to motivate the development of ISx---a new integer sort for co-design. ISx is a highly modular application implemented in the OpenSHMEM parallel programming model and supports both strong and weak scaling studies.
