Petaflop Radio Astronomy Signal Processing and the CASPER Collaboration

IF

In this video from the OpenFabrics International Developer Workshop 2014, SETI@home co-founder Dan Werthimer presents: Petaflop Radio Astronomy Signal Processing and the CASPER Collaboration. As a bellwether for exascale, radio astronomy projects like CASPER and the SKA telescope are pushing the limits of high performance computing.

Extreme Signal-Processing Meets HPC with Petascale Cross-Correlation

radio

“How do you cross-correlate 10,000 signals 100 million times per second? This is an example of the type of compute-bound problem facing modern radio astronomy, which, paralleling the paradigm shift in computing architectures, has transitioned from monolithic single-dish telescopes to massive arrays of smaller antennas. In this session we will describe how general-purpose HPC installations can be used to achieve scaling of a cross-correlation pipeline to petascale with all the flexibility of a purely-software implementation.”
