The Green500 is a biannual ranking of supercomputers, from the TOP500 list of supercomputers, in terms of energy efficiency . The list measures performance per watt using the TOP500 measure of high performance LINPACK benchmarks at double-precision floating-point format .
7-555: The Green500 List was created by Kirk W. Cameron and Wu-chun Feng, then both associate professors in Computer Science at Virginia Tech, in 2006. The power measurement techniques that form the basis of the run rules were based on Cameron's early work in supercomputer energy efficiency initially funded by the National Science Foundation (Awards: #0347683, #0614705). The first Green500 List was presented at
14-846: A peak performance of 350 TFLOPS per rack. As of November 2014, the L-CSC supercomputer of the Helmholtz Association at the GSI in Darmstadt Germany topped the Green500 list with 5.271 GFLOPS/W and was the first cluster to surpass an efficiency of 5 GFLOPS/W. It runs on Intel Xeon E5-2690 Processors with the Intel Ivy Bridge Architecture and AMD FirePro S9150 GPU Accelerators. It uses in rack watercooling and Cooling Towers to reduce
21-483: Is only slightly more efficient than the much larger Summit (which ranked 2nd while 1st on Top500 with 14.719 GFLOPS/W), using IBM POWER9 CPUs combined with Nvidia Tesla V100 GPUs. In June 2022, Hewlett Packard Enterprise took the lead, with all-AMD systems (CPUs and GPUs) in the 4 top positions, with the top position being over 50% more efficient than the previous year's top position. Later, in Nov. 2022, Lenovo took
28-586: The 2007 ACM/IEEE conference on Supercomputing and described in the December issue of IEEE Computer 40(12): 50-55 (2007). The list was initially met with some controversy since several key stakeholders (e.g., SGI, DOE Laboratories) failed to submit measurements by the report deadlines and were deprecated in the original list using power estimates based on U/L Ratings. A revised list was posted in February of 2008 to enable those failing to submit to provide updates to
35-704: The Green500 list with 2.499 LINPACK GFLOPS/W. Beacon is deployed by NICS of the University of Tennessee and is a GreenBlade GB824M, Xeon E5-2670 based, eight cores (8C), 2.6 GHz, Infiniband FDR, Intel Xeon Phi 5110P computer. As of June 2013, the Eurotech supercomputer Eurora at Cineca topped the Green500 list with 3.208 LINPACK GFLOPS/W. The Cineca Eurora supercomputer is equipped with two Intel Xeon E5-2687W CPUs and two PCI-e connected NVIDIA Tesla K20 accelerators per node. Water cooling and electronics design allows for very high densities to be reached with
42-622: The energy required for cooling. As of August 2015, the Shoubu supercomputer of RIKEN outside Tokyo Japan topped the Green500 list with 7.032 GFLOPS/W. The then-top three supercomputers of the list used PEZY-SC accelerators ( GPU -like that use OpenCL ) by PEZY Computing with 1,024 cores each and 6–7 GFLOPS/W efficiency. As of June 2019, DGX SaturnV Volta, using "NVIDIA DGX-1 Volta 36, Xeon E5-2698v4 20C 2.2GHz, Infiniband EDR, NVIDIA Tesla V100", tops Green500 list with 15.113 GFLOPS/W, while ranked only 469th on Top500. It
49-917: The list. Successive, updated Green500 Lists followed independently twice per year, in June at the International Supercomputing Conference (ISC) in Europe and in November at the US-based ACM/IEEE Supercomputing conference. In 2014, the Green500 List merged with the Top500 List and now requires only a single submission to participate in both lists. As of November 2012, an Appro International, Inc. Xtreme-X supercomputer ( Beacon ) topped
