The world's fastest supercomputer is currently held by El Captitan according to the latest Top500 chart. With a processing speed of 1.72 ExaFlop/s, it easily overtakes Frontier, the former world's fastest supercomputer with a speed of 1.102 Exaflop/s.
This is still below the original target of 2.7 ExaFlop/s when it was designed and there is still a lot of performance improvement to be done for it to at least reach 2.0 Exaflop/s. El Capitan is located at Lawrence Livermore National Laboratory in the United States and it uses HPE architecture and is equipped with 44,544 AMD MI300a APUs. The cost of building this supercomputer is estimated at around $600 million (~RM 2.68 billion).
El Capitan was developed specifically to simulate the explosion of nuclear weapons, weapons safety and the task of modernizing nuclear weapons for the future needs of the United States. From time to time it will also be used for the purpose of conducting scientific tests.
Although El Capitan is the world's fastest supercomputer, it is not the best for training artificial intelligence. The throne of the world's fastest AI supercomputer is still held by Aurora, which recorded a speed of 10.6 AI exaFLOPS.
