Rhea is a (512)-node commodity-type Linux cluster. The primary purpose of Rhea is to provide a conduit for large-scale scientific discovery via pre- and post-processing of simulation data generated on Titan. Users with accounts on INCITE- or ALCC-supported projects will automatically be given an account on Rhea. Director’s Discretion (DD) projects may request access to Rhea.
Each of Rhea’s nodes contain two 8-core 2.0 GHz Intel Xeon processors with Hyper-Threading and 128GB of main memory. Rhea is connected to the OLCF’s 32PB high performance Lustre filesystem “Atlas”.
