Prospero

Overview of Prospero

The Prospero community cluster consists of 19 Dell Quad-Processor 2.33 GHz Intel Xeon systems with 8 GB RAM and both Gigabit Ethernet and Infiniband interconnects. Each node has enough memory to run most jobs, and the high-speed Infiniband interconnect helps with many communication-bound parallel jobs. Compared to systems like Steele or Caesar, Prospero nodes have fewer processors per node, meaning that sizable multithreaded programs (parallel codes that do not use MPI) will be a poor fit.

All Prospero nodes run Red Hat Enterprise Linux 4 (RHEL4) and use PBSPro 9.x for resource and job management. Operating system patches are applied monthly or as security needs dictate. All nodes have been configured to allow for unlimited stack usage, as well as unlimited core dump size (though disk space and server quotas may still be a limiting factor).
