As one of the fastest supercomputers, Mira, our 10-petaflops IBM Blue Gene/Q system, is capable of 10 quadrillion calculations per second. With this computing power, Mira can do in one day what it would take an average personal computer 20 years to achieve.

Faster and more sophisticated computers mean better simulations and more accurate predictions. Mira is helping researchers to tackle more complex problems, achieve faster times to solutions, and create more robust models of everything from jet engines to the human body.

Consisting of 48 racks 786,432 processors, and 768 terabytes of memory, Mira is 20 times faster than Intrepid, its IBM Blue Gene/P predecessor at the ALCF. Mira was grown from the same DNA as Intrepid, but features many revolutionary advances.

As a machine for open science, any researcher with a question that requires large-scale computing resources can submit a proposal for time on Mira, typically in allocations of millions of core-hours, to run programs for their experiments. This adds up to billions of hours of computing time per year.
