| Abstract: |
The Hubble Space Telescope (HST) generates hundreds of science exposures and associated engineering data each day that must be transformed into archive products on short order. The OPUS pipeline data processing software, developed at the Space Telescope Science Institute (STScI), handles this demanding level of throughput by providing a distributed, concurrent pipeline processing environment for the set of applications that transform the raw telescope telemetry into archival products. The flexibility of the OPUS environment has convinced other space- and ground-based astronomical missions to adopt OPUS as their pipeline data processing system as well. OPUS does not place any restrictions on the types of processing done by the applications in a pipeline, however. Many computational problems having nothing to do with telescope telemetry processing stand to benefit from the distributed, concurrent environment OPUS has to offer. This paper describes one such research project underway at STScI that uses OPUS in a non-traditional sense: to coordinate the computation of numerical photoionization models involving hundreds of stellar sources. OPUS simplified the mechanics of generating these models by eliminating the need for writing complicated control scripts or developing specialized interprocess communication code to control the flow of processing. |
