Title: The Large Synoptic Survey Telescope Software Engineering, followed by Q&A session
By Frossie Economou (LSST),
Date: Thursday 23 June, from 11:00 -13h00 (SKAO, Jodrell Bank)
Local: Amphitheater, Instituto de Telecomunicações - Aveiro
Following the ENGAGE SKA participation in SKA Pre-Construction Design Consortia, we would like to invite you to assist to a live SKA Videoconf and discussion on a Large Scale Infrastructure Software Development. The LSST will create and manage about 200 Petabyte of data, requiring high availability, QoS, sourcing on the DevOps ideas from the telco/IT sector, from an Infrastructure as a Service (IaaS) to automatic information processing and object detection.
This videoconf is made available by the ENGAGE SKA Research Infrastructure, with support from the ATNOG and Integrated Circuits Groups @ IT and the TICE.PT sponsorship.
The Large Synoptic Survey Telescope (LSST) project will conduct a 10-year survey of the sky that will deliver a 200 petabyte set of images and data products that will address some of the most pressing questions about the structure and evolution of the universe and the objects in it. The LSST software is being developed in an iterative, agile, fashion. Primarily written in Python and C++, open source, and comprised of modular software ranging from science pipelines to web user interfaces, the LSST software stack will power the LSST and form a basis that other projects can reuse in the future. The LSST Data Management team is distributed across a number of partner institutions: the LSST Project Office, the Caltech Infrared Processing and Analysis Center, the University of Illinois National Center for Supercomputing Applications, Princeton University, SLAC National Accelerator Laboratory, and the University of Washington, but is also helped by contributors from the community, the LSST science collaborations, and other project subsystems.
Though engineering first light is still three years away, prototype versions of a number of the LSST software is already being tested on simulations and being applied to existing data. This talk will describe:
- The LSST software development process
- The tooling and infrastructure used to support it
- How the software and data quality requirements are managed and verified.
Frossie Economou has spent her career developing astronomical software, first at the Joint Astronomy Centre in Hawaii, and then at the LSST. In Hawaii she worked on the software suite that spanned both the Infrared (UKIRT) telescope and the sub-millimetre (JCMT). It included an automated data reduction system, an observatory control system and an end-to end Observation management system. She joined LSST in August 2014, as Technical Manager for Data Management (DM) and Education & Public Outreach (EPO). She splits her time between building a team to support the development and science quality activities of the far-flung DM group and planning for the software development effort of the EPO team. She is passionate about software quality, and currently evangelizes the idea of bringing DevOps ideas to the astronomical observatory
