CHAP: Available Resources

University users have access to HPC systems, data analysis and visualization clusters, disk storage resources, archival storage, and the full range of CISL support and consulting services.

Cheyenne. Cheyenne is a 5.34-petaflops, high-performance computer built for NCAR by SGI. The supercomputer was installed at the NCAR-Wyoming Supercomputing Center in the second half of 2016 and became operational early in 2017. More than 180 million Cheyenne system core-hours are allocated during each allocation cycle. See Cheyenne and University allocations for more information.

Casper. The Casper cluster is a new, heterogeneous system of specialized data analysis and visualization resources and large-memory, multi-GPU nodes. It is expected to be in production this summer. Casper is the successor to the Geyser and Caldera clusters, which have been in service since 2012 and will be decommissioned by the end of 2018.

Geyser/Caldera. University researchers can request access to the Geyser and Caldera analysis and visualization clusters as described in University allocations.

GLADE project space. University researchers with large allocations can request project space on CISL's GLADE resource. A portion of GLADE's 53-PB parallel file space is designated for use by projects whose disk needs are not met sufficiently by GLADE's scratch or work spaces. Please see the GLADE documentation for information about the file spaces that are available.

Campaign Storage. The NCAR Campaign Storage file system is available to universities that have project allocations. It is archival space for storing data on publication timescales and is not used for development work.

HPSS. CISL's HPSS archive is available to university projects. HPSS allocations are tracked separately from HPC resource charges. University projects receive up to 20 TB of long-term archive storage by default. Larger anticipated storage needs should be accompanied by a justification for the planned use.
