NANO 4
Supercomputer developed by the National Center for High-performance Computing in Taiwan
From Wikipedia, the free encyclopedia
NANO 4 (stylized in all capital letters, Chinese: 晶創26) is a supercomputer developed and operated by the National Center for High-Performance Computing (NCHC) in Taiwan. Announced in the mid-2020s as part of Taiwan's national high-performance computing and artificial intelligence (AI) infrastructure initiatives, NANO 4 is designed to support scientific research, industrial applications, and large-scale AI model training.[1][2]
The system forms part of Taiwan's broader efforts to strengthen domestic computing capabilities under programs such as the Forward-looking Infrastructure Development Program and national AI strategies. With a measured performance of 81.55 petaflops (Rmax), NANO 4 is among the most powerful supercomputers in Taiwan.[3] NANO 4 has also been associated with Taiwan's participation in global supercomputing benchmarks. As of November 2025, it is ranked 29th fastest in the world in the TOP500 supercomputer list.[4][5]

Installations
NANO 4 is installed at a high-performance computing facility in Tainan, Taiwan, operated by the National Center for High-performance Computing. The system forms part of a larger AI and cloud computing hub, which was opened on 11 December 2025 and intended to support national research infrastructure and industrial innovation.[7]
The system has been used for applications in artificial intelligence, telecommunications, cloud services, and digital content development. It is accessible to academic institutions, government agencies, and industrial users through allocation programs managed by NCHC.[8][9]
