Jesup is a 160 node testbed cluster, used to explore emerging hardware and software technologies. Some of the areas of exploration include Hadoop/MapReduce, Flash Storage, Virtualization, NoSQL technologies, and scalable databases. The node configuration is identical to the Carver nodes, quad-core Intel Xeon X5550 ("Nehalem") 2.67 GHz processors (eight cores/node) with 24 GB of memory per node.
Jesup is named in honor of philanthropist Morris Ketchum Jesup (1830 - 1908). Jesup's contributions to Tuskegee University enabled George Washington Carver to develop a mobile educational station that he took to farmers. The mobile stations were often termed Jesup Wagon's.
Hadoop jobs can be run on many of the NERSC systems, but Jesup provides local disk which can be beneficial to running Hadoop. Hadoop jobs are run dynamically by requesting nodes through the scheduler. For instructions on submitting Hadoop jobs see Using Hadoop.
