Syracuse University Gravitational wave And Relativity (SUGAR) Cluster
Welcome to the wiki pages of the Syracuse University Gravitational wave And Relativity (SUGAR) computing cluster.
SUGAR is a 320 CPU core computing cluster, with 96 Tb of storage, 640 Gb ram, operated by the SU Gravitational Wave Group in the Physics Department at Syracuse University.
For an overview of SUGAR, see the SUGAR web page. Funding for SUGAR is provided by Syracuse University.
