Preparing for the nation’s first exascale system, the upcoming HPE Cray EX Frontier “Frontier” system at the US Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL), has been a colossal undertaking.
Since the spring of 2020, ORNL staff members have made numerous modifications to the building and room that will house Frontier, a system that will be capable of more than 1.5 exaflops, or 1.5 quintillion calculations per second.
But before staff at the Oak Ridge Leadership Computing Facility (OLCF) could think about staging the massive system on the floor, a lot of work needed to be done. First, they needed to dismantle the center’s old Cray XK7 Titan supercomputer. A team from HPE—Cray at that time— removed more than 430,000 pounds of components for recycling from the old “Titan” supercomputer, to make way for Frontier.
The new mechanical plant can cool the equivalent of 40 megawatts of computational load and can be expanded to handle 70 megawatts—the equivalent power demand of about 55,000 US homes. Frontier’s warm-water mechanical plant saves more than a whopping $1 million annually in operating costs by eliminating the need for water chillers and cold water.
All in all, more than 200 individuals supported the construction and preparation work for the project.
The research was supported by DOE’s Office of Science.
