Dynamic Workloads and Cooling Controls: An Opportunity for Improved TCO
DescriptionWith recent exascale systems, power, energy and density have motivated moving to cold plate liquid cooling. However, the control systems are reactive. ORNL's control system takes minutes to deliver cold water, while Frontier instantaneously turns megawatts into waste heat. This highly interactive BoF will describe and discuss recent efforts in unifying power measurement systems at the compute node level with liquid cooling controls and CDUs. The discussion of future directions will include sites, system integrators and CDU vendors to discuss the benefits of first steps and the long-term goals of predictive load systems for proactive rather than passive cooling controls.
