The absence of new Chinese supercomputers from a list of the world's 500 fastest systems amounts to a major gap in the rankings, according to a co-founder of the Top500.
"The missing Chinese machines affect the Top500 list and alter the historical information that the list conveys," said Jack Dongarra, distinguished professor of computer science at the University of Tennessee in the U.S., and recipient of the 2021 ACM A.M. Turing Award.
"We know they exist, and research papers have been written about using these systems. We understand their competent performance, but nothing has been officially submitted."
