TerraWulf is a networked ‘Beowulf’ cluster of computers set up at RSES to provide convenient high end computing power for a range of demanding geoscience problems, particularly in the fields of thermochronology, seismology, geodesy, crustal and mantle dynamics, and landform evolution.
The cluster, consists of 162 nodes (1128 processor cores) connected through Gigabit and Infiniband switches which extend the range of potential applications of the cluster to both ’tight’ and ’loosely coupled’ codes. The Terrawulf II cluster was launched in June 2008 and upgraded and augmented with a new set of Terrawulf III nodes in 2011 and 2014.
The TerraWulf cluster is now being used for a variety of geoscience data processing and development of processing techniques, simulation and analysis of terrestrial processes as well as continuing development of inversion and data inference software. It is accessible directly through a local account and via the AuScope grid. Members of the AuScope Community can request a project account through the Access page
Two major upgrades of the TerraWulf compute cluster have been made possible by funding support from the National Collaborative Research Infrastructure Strategy (NCRIS) under the AuScope and AuScope/AGOS umbrellas combined with support from RSES providing a new and more powerful cluster.
The TerraWulf cluster consists of 62 IBM x3550 compute nodes (Terrawulf III) and 96 IBM x3455 compute nodes (Terrawulf II) linked to an IBM x3655 head node and a separate data storage server. The cluster has a total of 1128 compute cores with 15TB local storage, 16TB shared storage and up to 8GB RAM/core.
Detailed specifications, descriptions of software, current projects, publications and access details are available on the Terrawulf website
