Current and Next Generation Data Challenges at the National Radio Astronomy Observatory

Time 02/10/15 10:30AM-11:00AM

Room Second Floor Auditorium

Session Abstract

The US National Radio Astronomy Observatory (NRAO) has built and operates three
iconic radio telescopes in the United States: the recently upgraded Karl G.
Jansky Very Large Array (VLA), the Green Bank Telescope (GBT), and the Very Long
Baseline Array (VLBA). In addition, it is the North American partner for the
Atacama Large Millimeter/Submillimeter Array (ALMA) in Chile. The current model
for data management at the NRAO and ALMA, in which data is spooled at the
telescopes, transported and collected centrally, pipeline calibrated, duplicated
and made available through archive user interfaces with end-user data processing
and analysis will be discussed. Additionally limitations with the current model
and improvements envisaged for the medium term will be described, including
improved pipelining, use of external facilities, networked data transport, and
remote visualization. The large data management problem arising from the
proposed VLA Sky Survey (VLASS) will be described, as will potential data
management implications of the Next Generation VLA, which is in an early design stage.
