Top 500 Supercomputers

In November 2022, the Top 500 organisation published its list of the top performing supercomputers in the world. This list is published twice a year (June and November).

According to the latest results, the Frontier machine from HPE at Oak Ridge National Laboratory (ORNL) in the United States is the top performer supercomputer in the world. Frontier is followed by the Supercomputer Fugaku from Fujitsu at the Riken Center for Computational Science (R-CCS) in Kobe, Japan. In third and fourth places come two supercomputers located in the EU and both part of the European High-Performance Computing Joint Undertaking: the LUMI from HPE located in Finland and the Leonardo from Atos located in Bologna, Italy. Completing the top 5 comes Summit from IBM located in the United States.

Even though China does not have any supercomputer in the top 5, it has the highest share (32 %) of supercomputers among the top 500 with 162 machines. The United States come in second with a share of 25 % or 127 machines. In third place comes the EU (not shown in the figure) with a share of 20 % or a total of 102 supercomputers spread across 16 Member States. In terms of performance, however, the United States comes clearly on top with a share of 44 %.  In second comes the EU with a performance share of 23 % and in third Japan with 13 %. 

In terms of Vendors, Lenovo (China) shows the highest share (32 %) with 160 supercomputers produced, followed by HPE (United States) with a share of 20 % or 101 supercomputers produced and Inspur (China) with 10 % or 50 machines produced. From the top 10 biggest producers, only Atos (France) and MEGWARE (Germany) from the EU make the top 10 with 43 and 6 supercomputers produced, respectively.

The same website also ranks the supercomputers in terms of energy efficiency. On top comes the Henri system (Lenovo) at the Flatiron Institute in the United States (rank 405 in top 500), followed by Frontier TDS machine (HPE) also in the United States (rank 32 in top 500), and the Adastra machine (HPE) from France’s GENCI-CINES (rank 11 in top 500).
