Controlling cache utilization of HPC applications

Abstract

This paper discusses the use of software cache partitioning techniques to study and improve cache behavior of HPC applications. Most existing studies use this partitioning to solve quality of service issues, like fair distribution of a shared cache among running processes. We believe that, in the HPC context of a single application being studied/optimized on the system, with a single thread per core, cache partitioning can be used in new and interesting ways.
