Titan didn't re-test for TOP500, keeping last year's benchmark; ORNL's Jeff Nichols explains why

(Knoxville News Sentinel) The 200-cabinet Cray XK7 system known as Titan had barely been assembled last fall when it went through benchmark testing for the TOP500 supercomputer list, performing well enough to debut at No. 1 with a world-best performance north of 17 petaflops. Well, a new list, which is released every six months, is coming up in a matter of days, and Titan won't be up top. That's assuredly so....6/12
