TOP500

TOP500 is a list of the world's fastest supercomputers, first introduced in 1993 by Hans Meuer, Ernst Strohmaier, and Jack Dongarra at the University of Mannheim. The list is published twice a year, in June and November, and is widely regarded as the industry standard for measuring the performance of high-performance computing systems, such as those used by NASA, Los Alamos National Laboratory, and CERN. The TOP500 list is used by researchers and developers at institutions like Stanford University, Massachusetts Institute of Technology, and University of California, Berkeley to evaluate the performance of their systems and to identify areas for improvement, often in collaboration with companies like Intel, IBM, and Cray Inc.. The list has been widely covered in the media, including publications like The New York Times, Forbes, and Wired, and has been referenced by politicians and business leaders like Barack Obama and Bill Gates.

Introduction

The TOP500 list is based on the performance of supercomputers on the LINPACK benchmark, which measures the speed of a system in solving a large system of linear equations, a common task in scientific simulations used by organizations like National Science Foundation, European Organization for Nuclear Research, and Japanese Ministry of Education, Culture, Sports, Science and Technology. The list is compiled by a team of experts from University of Tennessee, National Energy Research Scientific Computing Center, and Lawrence Berkeley National Laboratory, who collect and analyze data from submissions from around the world, including those from China, United States, Japan, and European Union. The TOP500 list has been used to track the progress of high-performance computing over the years, and has been instrumental in driving innovation in the field, with contributions from researchers at Harvard University, University of Oxford, and California Institute of Technology. The list has also been used to evaluate the performance of cloud computing services like Amazon Web Services, Microsoft Azure, and Google Cloud Platform, and has been referenced by companies like Apple, Facebook, and Amazon.

History

The first TOP500 list was published in 1993, and was based on data from 120 supercomputers from around the world, including those from United States, Japan, and Europe. The list was initially compiled by Hans Meuer and Ernst Strohmaier, and was published in the Supercomputing conference proceedings, which is sponsored by organizations like IEEE Computer Society, Association for Computing Machinery, and National Science Foundation. Over the years, the list has undergone several changes, including the introduction of new benchmarks and the expansion of the list to include more systems, with contributions from researchers at University of Cambridge, University of Edinburgh, and University of Melbourne. In 1997, the list was expanded to include 500 systems, and has since been published twice a year, with data from submissions from around the world, including those from China, India, and South Korea. The list has been widely covered in the media, including publications like The Wall Street Journal, Forbes, and Bloomberg, and has been referenced by politicians and business leaders like Xi Jinping and Tim Cook.

Methodology

The TOP500 list is based on the performance of supercomputers on the LINPACK benchmark, which measures the speed of a system in solving a large system of linear equations, a common task in scientific simulations used by organizations like NASA, European Space Agency, and Japanese Aerospace Exploration Agency. The benchmark is run on each system, and the results are submitted to the TOP500 team, which includes experts from University of California, Los Angeles, University of Illinois at Urbana-Champaign, and University of Michigan. The team then compiles the data and ranks the systems based on their performance, using algorithms developed by researchers at Massachusetts Institute of Technology, Stanford University, and Carnegie Mellon University. The list is published twice a year, and is widely regarded as the industry standard for measuring the performance of high-performance computing systems, with contributions from companies like Intel, IBM, and Cray Inc.. The list has been used to evaluate the performance of cloud computing services like Amazon Web Services, Microsoft Azure, and Google Cloud Platform, and has been referenced by companies like Apple, Facebook, and Amazon.

Records and Rankings

The TOP500 list has been dominated by supercomputers from United States, China, and Japan, with systems like Summit, Sierra, and Sunway TaihuLight holding the top spots, and have been developed by researchers at Oak Ridge National Laboratory, Lawrence Livermore National Laboratory, and National Supercomputing Center in Wuxi. The list has also included systems from Europe, India, and South Korea, with contributions from researchers at CERN, European Organization for Nuclear Research, and Korea Institute of Science and Technology. The fastest system on the list has consistently been a supercomputer from United States or China, with the current record holder being Summit, a system developed by IBM, NVIDIA, and Red Hat, and located at Oak Ridge National Laboratory. The list has been widely covered in the media, including publications like The New York Times, Forbes, and Wired, and has been referenced by politicians and business leaders like Barack Obama and Bill Gates.

Current and Past Leaders

The current leader of the TOP500 list is Summit, a supercomputer developed by IBM, NVIDIA, and Red Hat, and located at Oak Ridge National Laboratory, with contributions from researchers at University of Tennessee, National Energy Research Scientific Computing Center, and Lawrence Berkeley National Laboratory. The system has a peak performance of over 200 petaflops, and is used for a variety of scientific simulations, including climate modeling and materials science, with collaborations with organizations like National Science Foundation, European Organization for Nuclear Research, and Japanese Ministry of Education, Culture, Sports, Science and Technology. Past leaders of the list have included Sierra, Sunway TaihuLight, and Tianhe-2, systems developed by researchers at Lawrence Livermore National Laboratory, National Supercomputing Center in Wuxi, and National University of Defense Technology. The list has been widely covered in the media, including publications like The Wall Street Journal, Forbes, and Bloomberg, and has been referenced by politicians and business leaders like Xi Jinping and Tim Cook.

Impact and Criticisms

The TOP500 list has had a significant impact on the development of high-performance computing, driving innovation and investment in the field, with contributions from companies like Intel, IBM, and Cray Inc.. The list has also been used to evaluate the performance of cloud computing services like Amazon Web Services, Microsoft Azure, and Google Cloud Platform, and has been referenced by companies like Apple, Facebook, and Amazon. However, the list has also been criticized for its focus on peak performance, which may not reflect the actual performance of systems in real-world applications, a concern raised by researchers at University of California, Berkeley, Stanford University, and Massachusetts Institute of Technology. Additionally, the list has been criticized for its lack of diversity, with systems from United States, China, and Japan dominating the list, a concern raised by organizations like European Commission, National Science Foundation, and Japanese Ministry of Education, Culture, Sports, Science and Technology. Despite these criticisms, the TOP500 list remains the industry standard for measuring the performance of high-performance computing systems, with contributions from researchers at Harvard University, University of Oxford, and California Institute of Technology.
