Abstract: The landscape of HPC is changing rapidly because of raising energy prices and concerns of increased OPEX, regulatory concerns around data center sustainability (reduction of carbon footprint, total power burden on the grid), and the expected increase in system power consumption as systems get larger. Customers are asking for solutions that help them manage the changing landscape.
Distributing a system power cap for the different nodes of a heterogeneous system is challenging. Providing different power distributions based on different allocation policies is impossible without an automated tool.
The System-Power-Capping tool presented in this paper is part of HPE’s vision toward holistic system power management software stack. The tool allows HPE and the customer to set a system power cap and to allocate node power based on different distribution algorithms and customer allocation policy, simplifying the process of setting power caps on a heterogeneous system. This paper will present experimental results that demonstrate the efficiency of various distribution algorithms using a customer hardware configuration as reference.
The recursive applicability of the approach (from data center to an individual node) can potentially help customers to improve the overall power allocation in the future.
