Advance Earth System science through HPC and data services

Computing is a foundational element of scientific research, and CISL provides a portfolio of advanced computing and data services specifically tailored for the atmospheric, geospace, and related sciences communities. At its core, CISL is a laboratory dedicated to providing advanced cyberinfrastructure to advance world-class science.

CISL curates, manages, and archives a rich, growing set of digital collections to which it provides free and open access, and that attracts more than 12,000 individual researchers who annually download 1.5 petabytes of data through various pathways. Moreover, CISL creates essential, widely used software such as visualization and analysis tools; creates frameworks for implementing parallel modeling workflows; creates and operates science gateways; provides user support and training for all of these services; and integrates its resources and services with regional, national, and international cyberinfrastructure.

CISL services evolve in response to changes in the underlying computational technologies and the scientific demands of the community, informed by the research and development activities performed under CISL Strategic Goal 2.

CISL provides world-class supercomputing and data services to its user community. From CISL’s services and support web pages, users can access CISL’s help desk and consulting services, as well as complete information about HPC systems, storage systems, data analysis and visualization systems, data collections, user documentation, and training. The quality of these services is and will remain a core value of the laboratory. However, the makeup of these services is not static: they continually change in concert with rapid changes in the underlying technologies and the scientific demands of our users:

  • CISL maintains and operates the physical facilities and cyberinfrastructure needed to support the atmospheric and related sciences.

  • A rich set of data collections is curated, managed, and archived for free and open access.

  • CISL creates essential, widely used software cyberinfrastructure such as data analysis and visualization tools and frameworks for modeling and science gateway construction.

  • User support and training are provided for all of these services.

  • All of these resources and services are integrated with regional and national cyberinfrastructure and services, and with the organizations that maintain them, such as the Front Range GigaPoP (FRGP), the Rocky Mountain Advanced Computing Consortium (RMACC), and NSF’s eXtreme Science and Engineering Discovery Environment (XSEDE).

In FY2016 CISL continued to operate the petascale Yellowstone supercomputing environment at the NWSC, including the supercomputer, the central disk storage system known as NCAR’s GLobally Accessible Data Environment (GLADE), two data analysis and visualization systems, the HPSS data archive, high-speed wide-area networking, and high-performance data transfer and sharing services. A wide range of computing projects pursued the research frontiers of weather phenomena, climate change, space weather, solar physics, and more.

CISL’s software CI capabilities continued to make important progress in FY2016, and overviews of these advances are provided in the sections below. Four years into Yellowstone’s production lifetime, CISL completed the NWSC-2 procurement effort that led to NCAR’s new supercomputing system named Cheyenne.
