In a news release on NASA's website, it states the computer can now complete "1.24 petaflops -- or a quadrillion calculations per second."
"To put this enormous number into perspective, if everyone in the world did one calculation per second for eight hours a day, it would take about 370 days to complete what this supercomputer can calculate in 60 seconds," the release says.
The computer is one of the smartest supercomputers in the world. It is used by 1,200 NASA researchers for a variety of projects, including processing large amounts of star data captured by the Kepler spacecraft and researching how solar flares impact technology on earth.
Pleiades was also used "for generating the 'Bolshoi' cosmological simulation -- the largest simulation of its kind to date -- to help explain how galaxies and the large-scale structure of the universe have evolved over billions of years."
Pleiades is located at the NASA Advanced Supercomputing (NAS) facility at Ames Research Center in Moffett Field, Calif., just 40 miles south of San Francisco. It was installed in 2008 and since that time has received eight major upgrades.
The Pleiades is also the name of a star cluster in the constellation Taurus also referred to as the Seven Sisters and M45.
