Cooling Compute Systems Efficiently, Anytime, Anywhere Workshop

December 13-14, 2021

The workshop convened leading experts in the field of datacenter thermal management with the objective to identify innovative research paths forward for the development of disruptive technologies that enable transformational high efficiency cooling methods for new and existing datacenters.

The goal of this workshop was to gather direct inputs from the community on the different metrics for a potential program aiming at improving the cooling efficiency of datacenters. Targeted outcomes included the identification of potential performance targets, approaches, and reliability targets. In addition, the intended outcome of the workshop involved the identification of potential cost targets for an effort in this technical area.

Furthermore, the aim of the workshop was to start teaming inception, break silos, and develop cross academia-natl. lab- business/start-up potential teams.

Finally, ARPA-E discussed the programmatic aspects of this potential program such as time required, testing aspects, others.
