SCD's goal is to enable the best atmospheric research in the world by providing and advancing high-performance computing technologies.
SCD offers computing, research datasets, data storage, networking, and data analysis tools to advance NCAR's scientific research agenda.
SCD’s machines are UNIX-based parallel computing architectures
Production Supercomputing Systems run tasks such as large simulations or models that require massive computing and data-handling resources.
IBM Cluster 1600 running AIX
IBM e1350 cluster running Linux
Data Analysis and Visualization Systems support data preprocessing prior to a job run and data postprocessing after a run
Tempest (SGI Origin3800 running IRIX)
Mass Storage System (MSS)
NCAR's Mass Storage System is a central, large-scale data archive that stores data used and generated by climate models and other programs executed on NCAR's compute servers.
On 21 July 2004,
NCAR's MSS surpassed
2 petabytes of data storage.
Some of the data stored on the MSS originate from field experiments and observations, however, the bulk of the data is generated by global climate-simulation models, mesoscale weather models, and other earth-science models that run on supercomputer.
Note: GAUs are also charged for storing files in the mass storage system (MSS) or file transfers from/to MSS to/from other machines
ASP GAU account number: 54042108 (also known as “project number”)
Needs to be specified in the batch scripts
ASP account number is NOT your default account number
Therefore: everybody needs a second (default) GAU account
(e.g. divisional GAU account)
University account - small request form for 1500 GAUs
These GAUs do not expire every month, one-time allocation
