    The cost of repair was borne by Cray and between 12 and 16 cabinets were repaired each week. [22] Throughout the repairs users were given access to the available CPUs. [22] On March 11, they gained access to 8,972 GPUs. [23] ORNL announced on April 8 that the repairs were complete [24] and acceptance test completion was announced on June 11 ...

    In October 2010, an upgraded version of the machine (Tianhe-1A) overtook ORNL's Jaguar to become the world's fastest supercomputer, with a peak computing rate of 2.57 petaFLOPS. [ 6 ] [ 7 ] In June 2011 the Tianhe-1A was overtaken by the K computer as the world's fastest supercomputer, which was also subsequently superseded.
