South Korea Rises to 9th in Global Supercomputer Rankings with Samsung's Debut

'Top 500' Aggregate Ranking Rises Compared to Last Year
Samsung's 'SSC-24' Achieves 18th Place Globally

South Korea ranked seventh in the world in terms of the number of supercomputers owned, and ninth in terms of performance. The new supercomputer introduced by Samsung Electronics achieved the highest domestic ranking.

KISTI announced that it participated in ISC High Performance 2025 (hereinafter ISC 2025), held from June 10 to June 13.

According to the Korea Institute of Science and Technology Information (KISTI) on June 12, South Korea ranked seventh with a total of 15 supercomputers in the country-by-country ranking of the 'Top 500' global supercomputer list, which was announced at the International Supercomputing Conference (ISC 2025) being held in Hamburg, Germany, on June 10.

Based on the aggregate measured performance by country, South Korea ranked ninth with 323.11 petaflops (PFlops). One petaflop is the ability to perform one quadrillion calculations per second. In the aggregate performance ranking by country, South Korea rose one place from tenth in the ranking announced in November last year, thanks to the addition of SSC-24.

Among individual computers, Samsung Electronics' 'SSC-24' made its debut at 18th place, the highest ranking among domestic supercomputers. Naver's 'Sejong' ranked 50th, followed by Kakao Enterprise's 'KakaoCloud' at 52nd. KISTI's fifth supercomputer 'Nurion' was ranked 109th, with a measured performance of 13.93 PFlops.

In the device ranking, 'El Capitan' at the Lawrence Livermore National Laboratory (LLNL) in the United States retained its position as the world's number one supercomputer for the second consecutive year.

Globally, there was no change among exascale supercomputers, with 'El Capitan,' 'Frontier' at the Oak Ridge National Laboratory (ORNL) in the United States (2nd), and 'Aurora' at the Argonne National Laboratory (ANL) in the United States (3rd). However, 'Jupiter Booster' at the Juelich Supercomputing Centre in Germany made its debut at fourth place.

KISTI stated, "We are preparing to introduce the sixth supercomputer, aiming for completion in the first half of next year. It is expected to have a theoretical performance of 600 petaflops."
