The Atmospheric Radiation Measurement (ARM) user facility has a new high-performance computing cluster available for users’ big-data needs.

Based at the ARM Data Center, the new Cumulus replaces the Stratus cluster and the original Cumulus cluster.

The new cluster has much more processing power, enabling it to do the work of ARM’s previous two clusters. The new Cumulus has 16,384 processing cores. This is about four times as many cores as the original Cumulus and 15 times as many as Stratus.

Researchers can use the new cluster for ARM-approved science projects. To use the cluster, researchers must first submit a request for access. Note that any request for ARM computational resources must include a clear use of ARM observational data. Requests will be reviewed quarterly.

Another use of Cumulus is for the development and operations of the Large-Eddy Simulation (LES) ARM Symbiotic Simulation and Observation (LASSO) activity. LASSO packages LES simulations, relevant ARM observations, skill scores, and diagnostics for researchers and modelers. The LASSO team is working on a beta release of deep convection data from a 2018–2019 ARM field campaign in Argentina.

The cluster will also support other computationally intensive activities by the ARM facility, including radar data processing, large-scale reprocessing, creation of science data products, and data quality analysis.
