Opportunities

Many new scientific and technical staff are needed now in specific initiatives or strategic research areas in the Computing and Computational Sciences Directorate. Opportunities also exist for joint tenure-based positions with our university partners.

Supercomputing at ORNL

Primary CCSD machines include:

Jaguar: currently ranked the second most powerful supercomputer in the world, is a combined Cray XT3/XT4 system with a peak performance of 119 trillion floating point operations per second (119 teraflops). The system contains 11,708 processors, 11,508 of which are compute processors and the remainder service processors. Approximately 600 terabytes of scratch disk space are available in the system for use by the Lustre file system.

Plans call for Jaguar to be upgraded to a peak performance of 250 teraflops in late 2007. The upgrade will replace the current dual-core processors with quad-core processors.

Phoenix: a Cray X1, with 512 multi-streaming vector processors and 2 TB of globally addressable memory.

Ram: a 256-processor SGI Altix with 2 TB of shared memory. Each processor is a 1.5 GHz Intel Itanium2.

Cheetah: a 27-node IBM p690 system, where each node has thirty-two 1.3 GHz Power4 processors. Most of the nodes have 32 GB of memory, but five of the nodes have 64 GB of memory, and two have 128 GB of memory.

Eagle: a 184-node IBM RS/6000 SP, 176 "thin" nodes have four 375 MHz Power3-II processors and 2GB of memory while 8 "wide" nodes have two 375 MHz Power3-II processors and 2GB of memory.
