Meet the NASA computer used for most climate simulations
The actual computer we do all of our climate simulations on (well, a little bit of it). pic.twitter.com/Z1qSFlgJwm

The system architecture is made up of multiple scalable units. The list below describes the total aggregate components of the system and its individual scalable units.
- 67 Racks (compute, storage, switches, and more)
- 1.0018 Pflop/s
- 43,240 Total Cores
File System and Storage
- IBM GPFS
- 2.46 PB Storage
- Operating System: SLES
- Job Scheduler: PBS
- Compilers: C, C++, Fortran (Intel and PGI) Source NCCS
NASA Goddard Introduces the NASA Center for Climate Simulation
The new center more than doubles the computing capacity available at Goddard one year ago and expands other services to support NASA’s growing climate data needs. Enhanced NCCS capabilities include:
- The 15,000-processor “Discover” supercomputer with a peak performance of nearly 160 trillion operations per second.
- A 17- by 6-foot multi-screen visualization wall for displaying high-definition movies of simulation results and interactive data visualizations.
- An analysis system offering dedicated software tools for visualization, workflow management, and diagnostics.
- A new data management system for accessing and locating data within NCCS’ multi-petabyte (peta = 1,000 trillion) archive.
- An Earth System Grid node for distributing simulation data from NASA’s contributions to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC). Link
Climate modeling groups all across the world are racing to add their contributions to the CMIP5 archive of coupled model simulations. This coordinated project, proposed, conceived and specified by the climate modeling community itself, will be an important resource for analysts and for the IPCC AR5 report (due in 2013), and beyond.
