Jesup Testbed

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 Cluster

80 of Jesup's 160 nodes are used to run a Hadoop cluster, which has a dedicated Hadoop Distributed File System (HDFS).  Any NERSC user may request access to this cluster by submitting a request through SerivceNow.  For instructions on submitting Hadoop jobs see Using Hadoop.
