Titan History
"and in the process bump the “Titan” machine at the USA's Oak Ridge National Laboratory off the podium for just the third time in the history of the TOP500 list of the world's mightiest supercomputers."
Really!? This is the third time that Titan has dropped out of the top 3?
I think what you were trying to say is "and in the process made this only the third time in the history of the list when the USA has no machine in the top 3".
