The Cray Graph Engine is an RDF database that supports SPARQL as its query language. Extensions to SPARQL have been added to support a variety of specific graph algorithms. Built-in functions (of which there are many) include geospatial functions. Both post-graph and pre-graph analysis can be performed using R. From a hardware perspective the Cray Graph Engine is available on any Cray system that includes the Cray Aries interconnect. The Cray Graph Engine is also available for Cray’s XC line of supercomputers, as part of an AI and Analytics suite called Urika-XC. This software-only package contains CGE plus Spark, R and a suite of Deep learning packages.
