Frontier Supercomputer Breaks the ExaFLOPS Barrier, Tops the TOP500 List
takyon writes:
The Frontier supercomputer at the Oak Ridge National Laboratory (ORNL) has exceeded 1.1 exaFLOPS (Rmax), leading the June 2022 TOP500 list as the world's fastest supercomputer and the first truly "exascale" system.
Frontier uses 9,408 64-core Epyc 7A53 CPUs and 37,632 AMD Instinct MI250X GPUs. It has 4.6 petabytes each of DDR4 and High Bandwidth Memory.
Frontier also reached #2 on the June 2022 Green500 list at 52.227 gigaFLOPS/Watt, behind the smaller Frontier Test & Development System:
Previously, Frontier had been characterized as a two peak exaflops system, but its first Top500 benchmark measures some 1.686 peak exaflops. (Oak Ridge said that there remains "much higher headroom on the GPUs and the CPUs" to achieve the two peak exaflops target.) Outside of Linpack and the Top500, the system benchmarks at 6.88 exaflops of mixed-precision performance on HPL-AI. The team ran out of time and was not able to submit an HPCG benchmark.
[...] Frontier also achieved another win out of the gate: second place on the spring 2022 Green500 list, which ranks supercomputers by their flops per watt. The Oak Ridge team accomplished this by delivering those 1.102 Linpack exaflops in a 21.1-megawatt power envelope, an efficiency of 52.23 gigaflops per watt (which works out to one exaflops at 19.15 megawatts). This puts the system well within the 20-megawatt exascale power envelope target set by DARPA in 2008-a target that had been viewed with much skepticism over the ensuing 14 years. Frontier was only outpaced in efficiency by its own test and development system (Frontier TDS, aka "Crusher"), which delivered 62.68 gigaflops per watt.
#10: 30.05 petaflops (Nov. 2021) 46.10 petaflops (June 2022)
#100: 4.79 petaflops 5.39 petaflops
#500: 1.65 petaflops 1.65 petaflops (both are Lenovo C1040, Xeon E5-2673v4 20C 2.3GHz systems)
