Supercomputing

This page aims to

• overview installations of GRASS GIS in supercomputing (HPC, HTC) environments and related applications
• document best practices of processing big geospatial data, common mistakes and errors and how to work-around them

Overview of GRASS GIS in supercomputing environments

• Supercomputer "Aurel", 4096 CPU cores (Power7 architecture), features GRASS GIS 7.4
• GRASS GIS in JRC's JEODPP, A versatile data-intensive computing platform for information retrieval from big geospatial data
• henry2 at NCSU (Intel Xeon based Linux cluster; GRASS GIS 7.2.0 installed around 2017)
• ROGER, the CyberGIS supercomputer at NCSA UIUC (batch compute nodes: 24x, 10 cores, 2.6 GHz, 256 GB RAM, 500 GB of local storage, cluster-wide General Parallel File System (GPFS) 4.5PB; GRASS GIS available alongside GDAL, PDAL, Geotools, and R)

Processing Practices
