NCAR Computational and Information Systems Laboratory (CISL)

NCAR’s supercomputing resources serve over 1,400 users in a wide variety of disciplines including climatology, meteorology, oceanography, astrophysics, fluid dynamics, and turbulence. In particular, CISL provisions a balanced suite of high-performance resources that allows today’s Earth System models to simulate atmosphere, ocean, sea ice, and land surface processes with increasing fidelity.

CISL operates and oversees computing facilities, both virtual and physical, and ensures that the hardware and software needs of the scientific community are met. CISL develops and curates research data sets and maintains online user access to the archive for nearly 10,000 users a year. CISL also provides virtualization and grid technologies, promoting collaboration and sharing of valuable scientific resources.

CISL has been providing world-class supercomputing and data management services to its user community for decades.

CISL provides computing, storage, data analysis, visualization, networking, and archival systems customized to support the atmospheric and related sciences.

NCAR Yellowstone

  • Yellowstone — A 1.5-petaflops high-performance computing system with 72,576 processor cores and 145.1 terabytes of memory. It is housed at the NCAR-Wyoming Supercomputing Center (NWSC).
  • Geyser and Caldera — The Geyser and Caldera clusters are specialized data analysis and visualization resources within the data-centric Yellowstone environment.
  • GLADE — The central GLADE file system significantly expands the disk space available to CISL users and allows users to access their data from both HPC and DAV systems.
  • HPSS — CISL operates a High-Performance Storage System (HPSS) environment for archival storage. CISL's HPSS currently stores more than 30 PB of data in support of CISL computing facilities and NCAR research activities.
  • Janus — In collaboration with the University of Colorado, NCAR controls approximately 10% of the Janus. The Janus system is a Dell Linux cluster that is housed on the CU-Boulder campus and has a high-speed networking connection to NCAR's computing and data storage systems.

National Center for Atmospheric Research

The National Center for Atmospheric Research (NCAR) is a federally funded research and development center devoted to service, research and education in the atmospheric and related sciences. NCAR’s mission is to understand the behavior of the atmosphere and related physical, biological and social systems; to support, enhance and extend the capabilities of the university community and the broader scientific community – nationally and internationally; and to foster transfer of knowledge and technology for the betterment of life on Earth. The National Science Foundation is NCAR's primary sponsor, with significant additional support provided by other U.S. government agencies, other national governments and the private sector.
