Although the Frontier supercomputer, located at Oak Ridge National Laboratory, is considered the fastest supercomputer in the world because it tops the global Top500 list, it may not be the de facto leader. Some scientific papers suggest that Chinese supercomputers, the Sunway and Tianhe-3, may surpass Frontier in performance, believes Jack Dongarra, a co-founder of Top 500.
"The Chinese have machines that are faster," Dongarra told the Wall Street Journal. "They just have not submitted the results."
