DescriptionThe power scaling challenges associated with exascale
systems is a well-known issue. In this work, we
introduce the Global Extensible Open Power Manager
(GEOPM): a tree-hierarchical, open source runtime
framework we are contributing to the HPC community to
foster increased collaboration and accelerated progress
toward software-hardware co-designed energy management
solutions that address exascale power challenges and
improve performance and energy efficiency in current
systems. Through its plugin extensible architecture,
GEOPM enables rapid prototyping of new energy management
strategies. Different plugins can be tailored to the
specific performance or energy efficiency priorities of
each HPC center. To demonstrate the potential of the
framework, this work develops an example plugin for
GEOPM. This power rebalancing plugin targets
power-capped systems and improves efficiency by
minimizing job time-to-solution within a power budget.
Our results demonstrate up to 30% improvements in the
time-to-solution of CORAL system procurement benchmarks
on a Xeon Phi cluster.
