The CSCAMM Research SP System

In September of 2001, Center for Scientific Computation and Mathematical Modeling at the University of Maryland acquired an IBM RS/6000 Scalable POWERparallel System(SP) for research computing. It came with 8 4-cpu Power3-II wide nodes. one 1-cpu RS/6000 44p series model 170 for control workstation and one 2-cpu 44p series 270 for front-en machine.

All nodes on the SP frame are interconnected with SP high-speed switch MX2. Its peak data throughput is 1.5GB/second. The SP system is also connected to the Internet through GigaBit ethernet network.

All SP nodes are accessible through secure shell client. IBM compilers, and several public domain software are available on the SP. In addition, IBM software products designed to use the SP switch for messages transfer are installed, including Parallel ESSL, Distributed Debugger and Parallel Environment. These products offer tools for compiling, running, monitoring, profiling, tuning and debugging parallel programs.

The SP nodes process batch jobs via the IBM Loadleveler load-balancing batch queueing system. Both serial and parallel jobs may be submitted to the dawson SP nodes. Interactive use of the dawson SP is allowed, but a limit of 20 minutes of elapsed CPU time per interactive process is strictly enforced.
