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
- GRASS GIS 8 on LUMI Supercomputer in Finland: https://docs.csc.fi/apps/grass/
- 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
- Hazel at NCSU (Intel Xeon based Linux cluster; GRASS GIS available since 2017)
Past:
- 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
See page Parallel GRASS jobs for Cluster and Grid computing with parallelized code, Job scheduler, and GRASS on a cluster
