"I don't know of another system that is going to be anywhere near the performance and the power of this machine" in China, said Jack Dongarra, a supercomputer expert on the Oak Ridge research staff who is a professor at the University of Tennessee and recently inspected the system in Tianjin last week. "It is quite impressive."
