| 释义 |
The HPCG (high performance conjugate gradient) benchmark is a supercomputing benchmark test proposed by Michael Heroux from Sandia National Laboratories, and Jack Dongarra and Piotr Luszczek from the University of Tennessee.[1][2] It is intended to model the data access patterns of real-world applications such as sparse matrix calculations, thus testing the effect of limitations of the memory subsystem and internal interconnect of the supercomputer on its computing performance.[3] Because it is internally I/O bound, HPCG testing generally achieves only a tiny fraction of the peak FLOPS of the computer.[4] HPCG is intended to complement benchmarks such as the LINPACK benchmarks that put relatively little stress on the internal interconnect.[5] The source of the HPCG benchmark is available on GitHub[6]. As of June 2018, the Summit supercomputer held the top spot in the HPCG performance rankings, followed by the Sierra and the K computer.[7] References1. ^{{cite news|url=http://www.hpcwire.com/2014/06/26/development-pushes-ahead-new-hpc-benchmark/#|title=New HPC Benchmark Delivers Promising Results|last=Hemsoth|first=Nicole|date=June 26, 2014|publisher=HPCWire|accessdate=2014-09-08}} 2. ^{{Cite web|url=http://www.sandia.gov/~maherou/docs/HPCG-Benchmark.pdf|title=Toward a New Metric for Ranking High Performance Computing Systems|last=Dongarra|first=Jack|last2=Heroux|first2=Michael|date=June 2013|website=|publisher=Sandia National Laboratory|access-date=2016-07-04}} 3. ^{{Cite web|url=https://www.hpcwire.com/2015/07/15/linpacks-companion-metric-gains-traction/|title=LINPACK's 'Companion Metric' Gains Traction|last=Trader|first=Tiffany|date=2015-07-16|website=HPCwire|access-date=2016-07-04}} 4. ^{{Cite web|url=https://www.epcc.ed.ac.uk/blog/2015/07/30/hpcg|title=HPCG: benchmarking supercomputers|last=Jackson|first=Adrian|date=30 July 2015|website=www.epcc.ed.ac.uk|publisher=EPCC at the University of Edinburgh|access-date=2016-07-04}} 5. ^{{Cite web|url=http://insidehpc.com/2015/07/latest-hpcg-performance-list-complements-top500/|title=Latest HPCG Performance List Complements TOP500|last=Brueckner|first=Rich|date=2015-07-13|website=Inside HPC|language=en-US|access-date=2016-07-04}} 6. ^{{cite web |title=HPC-G source code |url=https://github.com/hpcg-benchmark/hpcg |website=Github |accessdate=6 February 2019}} 7. ^{{cite web |title=US Regains TOP500 Crown with Summit Supercomputer, Sierra Grabs Number Three Spot |url=https://www.top500.org/news/us-regains-top500-crown-with-summit-supercomputer-sierra-grabs-number-three-spot/ |website=Top500 |publisher=Top500.org |accessdate=28 June 2018}} See also
