Contribution
It proposes a detailed design for the SKA pulsar search engine and addresses key challenges in processing large-scale data in real time.
Findings
Expected to discover many new pulsars with SKA1
Design of a high-performance signal processing pipeline
Addressed data handling and processing challenges
Abstract
The Square Kilometre Array will be an amazing instrument for pulsar astronomy. While the full SKA will be sensitive enough to detect all pulsars in the Galaxy visible from Earth, already with SKA1, pulsar searches will discover enough pulsars to increase the currently known population by a factor of four, no doubt including a range of amazing unknown sources. Real time processing is needed to deal with the 60 PB of pulsar search data collected per day, using a signal processing pipeline required to perform more than 10 POps. Here we present the suggested design of the pulsar search engine for the SKA and discuss challenges and solutions to the pulsar search venture.
