These NCAR supercomputing, data storage, and archive systems support the development of climate models, weather forecasting, and other critical research.
Access to these resources is available through several allocation opportunities. In general, researchers who are supported by the National Science Foundation to pursue work in the atmospheric sciences or computational science in support of the atmospheric sciences are eligible to apply.
The 1.5-petaflops Yellowstone HPC system is an IBM iDataPlex cluster with 72,576 Intel Sandy Bridge processors. Yellowstone was deployed to enable dramatic improvements in the scientific capabilities of a broad spectrum of important atmospheric science applications. Yellowstone serves researchers across the United States and around the world.
The analysis and visualization resource comprises two systems. Geyser offers large-memory nodes (1 TB in each node) and is used for large-scale analysis and post-processing tasks, including 3D visualization. Caldera is designed to run distributed-memory parallel applications and for development and testing of general-purpose GPU (GPGPU) code.
This central file and data storage resource consists of file system servers and storage devices with 16 PB of usable capacity. It is shared by the Yellowstone system and the Geyser and Caldera analysis and visualization clusters. The centralized file systems allow scientists to generate model output on the supercomputer, then analyze or visualize it on the other clusters without needing to move data between separate systems.
BlueM is the Colorado School of Mines, which is housed in NCAR's Mesa Lab colocation facility. NCAR researchers can request access to the system for code porting, testing and evaluation. This high-performance computing system contains two independent compute partitions that share a common 480 TB file system but different architectures. Each is optimized for a particular type of parallel application.
The Antarctic Mesoscale Prediction System (AMPS) uses the Erebus cluster in support of the United States Antarctic Program, Antarctic science, and international Antarctic efforts. AMPS is an experimental, real-time numerical weather prediction capability that provides numerical guidance from the Weather Research and Forecasting (WRF) model with twice-daily forecasts covering Antarctica.
The High Performance Storage System (HPSS) consists of tape libraries with storage capacity of more than 160 petabytes at the NCAR-Wyoming Supercomputing Center (NWSC) and more than 15 petabytes of disaster-recovery data storage at the Mesa Lab in Boulder.
