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.
