Nuclear worries stop Intel from selling chips to Chinese supercomputers

Intel and Nvidia have been blocked from selling chips to four Chinese supercomputer centers because the U.S. government has determined those computers are used for "nuclear explosive activities." TianHe-1A and TianHe-2 are among the world's fastest supercomputers. They both run almost entirely on Xeon processors made by Intel. TianHe-1A also uses chips from Nvidia.
