The One Degree Imager (ODI), an optical imager on the WIYN 3.5m telescope at Kitt Peak, Arizona, is designed to deliver atmosphere-limited image quality (<0.4”) over a one degree field of view. The ODI Pipeline, Portal, and Archive (ODI-PPA) is a web science gateway that provides astronomers a single point of access to ODI data, and rich computational and visualization capabilities. Its goal is to support scientists in handling complex data sets, and to enhance the WIYN observatory's scientific productivity beyond data acquisition.
ODI-PPA lets astronomers do their science -- while the gateway seamlessly manages the data!
Brief Technical Description
ODI-PPA leverages CyberInfrastructure Indiana University including the geographically replicated 42 PB Scholarly Data Archive (SDA) tape system for safe archival of data, the 1 Petaflop Cray Big Red II and Karst supercomputers, and the 5 PB Data Capacitor shared file system for temporary staging of data. A set of download servers running Apache HTTP handle all download requests. A replicated MySQL cluster and a RabbitMQ event cluster handle all PPA database and message bus needs respectively.
