Abstract
This paper describes a kernel scheduling algorithm that is based
on co-scheduling principles and that is intended for parallel applications
running on 1000 cores or more where inter-node scalability
is key. Experimental results for a Linux implementation on a
Cray XT5 machine are presented.1 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.
