The Square Kilometer Array: Taming Exascale Data Flows to Explore the Radio Universe
SESSION: Climbing the Computational Wall
EVENT TYPE: Masterworks
TIME: 10:30AM - 11:15AM
SESSION CHAIR: Ray Bair
ABSTRACT: Radio astronomy has been enabled by and is dependent on three technologies: digital signal processing, computing, and networking technologies. Radio astronomers working in an international consortium will build the world's largest, most sensitive, fastest radio telescope, the Square Kilometre Array. The SKA will be one of the foremost scientific instruments in the world, addressing some of the most important questions in astrophysics and cosmology. The SKA will naturally stress the state of the art in the three technology areas mentioned above. Among the most notable technical aspects of the SKA is the very large data rate -- exceeding 10 Pbit/s over long-distances -- digital signal processing requiring about 1 exaflop/s for processing into images, and 1 exabyte of science data per week. The use of supercomputers in the digital signal processing chain and the interaction between the computing architecture and the physics and algorithmics of the measurement process will be discussed.
