Abstract
This paper describes a kernel scheduling algorithm that is based on coscheduling
principles and that is intended for parallel applications running
on 1000 cores or more. Experimental results for a Linux implementation on
a Cray XT5 machine are presented. The results indicate that Linux is a
suitable operating system for this new scheduling scheme, and that this
design provides a dramatic improvement in scaling performance for
synchronizing collective operations at scale.
