TAIPEI, Taiwan — The Supercomputing Research Center (SRC) of National Cheng Kung University (NCKU) has built the world’s first ever switchless cluster computing system. Known also as the “CK-Star,” this computing system connects eight computers without switch control and broke Intel’s performance record, according to a press release by the university. The single supercomputer, built jointly by NCKU and Gigabyte, was recorded to have reached 3.7 teraflops (3.7 trillion floating-point operations) in terms of computing performance.

Desginated the “GS-R22PHL,” this supercomputer is currently the highest performing single supercomputer to date, thus setting a world record in the field of supercomputers and a new milestone in the history of computing. Together with computer systems provided by Acer, “CK-Star” was jointly built by NCKU SRC Director Chi-Chuan Hwang and mainland China’s National Supercomputing Center in Jinan (NSCCJN) “Taishan Scholar” Yuefan Deng, who is also a distinguished professor at the State University of New York (SUNY).

The GS-R22PHL single supercomputer is a joint collaboration between NCKU and Gigabyte. Hwang added that CK-Star is the most unique switchless cluster supercomputer, compared with traditional cluster supercomputers which require switch control systems that control interaction between nodes.

He explained that the weakness of traditional designs is that switches will become performance bottlenecks as the number of nodes increases.
