Abstract: The goal for procurement of HPC systems is to identify optimal solutions to both technical and financial targets that maximize the contribution of the system to the organization's mission. It is important to consider total cost of ownership, cooling and power requirements, the needs for interfacing with the HPC facility, and power management and control. In this BoF, we present energy efficiency highlights in recent procurements by four sites and encourage audience participation. Presenting sites are from Japan on power efficiency; Europe on cooling enhancements; the United States on future efficiency requirements as well as on facility integration and efficiency.
Long Description: The Energy Efficient HPC Working Group (EE HPC WG) - https://eehpcwg.llnl.gov/ - has spent the past year analyzing public information of eleven major HPC procurements to extract energy efficiency related requirements, and has substantive findings to share. The EE HPC WG Procurement Considerations Team collected, reviewed and analyzed for best practices 11 different recent procurement documents from the United States, Europe and Japan. The BOF will share exciting findings in recent HPC procurements with the broader community, and the ensuing discussion will be included in the EE HPC WG publicly available Energy Efficiency Considerations for HPC Procurements document.
This BOF is a continuation of past participation starting in SC13 at the EE HPC WG Annual Workshop with the initial formulation and documentation of energy efficiency considerations for HPC procurements. The topic was discussed again at the SC14 EE HPC WG Annual Workshop and then at BoFs in SC16 and SC17. The SC17 BoF discussed Total Cost of Ownership and HPC System Procurements. Participation in the BOFs has been strong with approximately 75 participants at both SC16 and SC17.
Energy efficiency is a growing concern in HPC system procurements worldwide. The EE HPC WG membership reflects this well, with regular participation from sites across the world, representing government, education, and industry. The goal of the EE HPC WG is to open the benefits of discussion and findings up to the entire HPC community. The SC18 BOF will provide an excellent opportunity to share State of the Practice from four sites and interact with the HPC community to identify findings of interest. The Joint Center for Advanced HPC will present on their approach to power efficiency in a 2016 procurement for an exaflop-class system on the road to 2020. The Leibniz Supercomputing Centre (LRZ) will highlight cooling efficiency of the CoolMUC-3 system in 2017. Sandia National Laboratory will propose a view of what energy efficiency might look like in 5-10 years. The Collaboration of Oak Ridge, Argonne, and Livermore (CORAL) will discuss facility integration as it relates to energy efficiency with the 2018 CORAL-2 procurement.
The Energy Efficient HPC Working Group has published a document on Energy Efficiency Considerations for HPC Procurements. Lessons learned and best practices from this BoF would be captured in an updated version of that document.
