NOAA’s supercomputer upgraded

The  National Oceanic and Atmospheric Administration’s Cray supercomputer, which is housed at Oak Ridge National Laboratory, has received another upgrade, and the new system reportedly has a peak capability of 1.76 petaflops.

NOAA and ORNL have a longstanding relationship, sharing resources and working together on climate research. NOAA’s supercomputer at ORNL’s National Center for Computational Sciences has been known as Gaea, Mother Earth.

According to Buddy Bland, director of the Oak Ridge Leadership Computing Facility, the new system is a Cray XC40, and it’s known in-house as C3.

“C3’s peak capability is 1.76 PF. The previous Gaea systems (C1 and C2) had a combined peak capability of 1.1 PF,” Bland said. “We started acceptance on the new C3 system on Nov. 16, 2015 and completed it on Dec. 29, 2015.  We operated both the old and new GAEA systems together for a small period of time to give the user community an opportunity to transition to the new system.

“The final piece of the old GAEA system, C1, is scheduled to be decommissioned on April 29, 2016,” he said.
