As of my last knowledge update in January 2022, here were the top 3 fastest supercomputers in the world:
-
Fugaku (Supercomputer) – Located in Japan:
- Manufacturer: RIKEN and Fujitsu
- Performance: 442 petaflops (peak)
- Fugaku, also known as the RIKEN Center for Computational Science’s supercomputer, was the fastest in the world at that time. It is a joint project between RIKEN and Fujitsu and is known for its exceptional performance in various scientific and research applications.
-
Summit (Supercomputer) – Located in the United States:
- Manufacturer: IBM
- Performance: 200 petaflops (peak)
- Summit is based at the Oak Ridge National Laboratory in Tennessee, USA. It was the fastest supercomputer in the United States and the second-fastest in the world in terms of peak performance in 2022.
-
Sierra (Supercomputer) – Located in the United States:
- Manufacturer: IBM
- Performance: 125 petaflops (peak)
- Sierra is another supercomputer at the Lawrence Livermore National Laboratory in California, USA. It was among the top supercomputers globally and played a vital role in various scientific and national security research projects.
Please note that the rankings and performance of supercomputers can change over time as new systems are developed and deployed. To get the most up-to-date information on the world’s fastest supercomputers, I recommend checking the latest reports from organizations like TOP500 or other authoritative sources in the field of high-performance computing.
