Automated reduction of a very large body of data from the Spitzer Space Telescope requires an intricate and very flexible software system to support more than 50 different pipelines executing on a large distributed computing cluster. Additionally, in order to correct many instrumental signatures and calibration features, a variety of complex algorithms need to be utilized to process and distribute calibrated images and spectra from nearly 5 million instrument frames that are collected by the observatory every year. A sample of the complexities that needed to be accommodated both in system architecture and design as well as signatures encountered and associated algorithms will be described.
