The SPIIR online coherent pipeline to search for gravitational waves from compact binary coalescences
Qi Chu, Manoj Kovalam, Linqing Wen +16
This paper presents the SPIIR pipeline used for public alerts during the third advanced LIGO and Virgo observation run (O3 run). The SPIIR pipeline uses infinite impulse response (…
Cloud based Real-Time and Low Latency Scientific Event Analysis
Chen Yang, Xiaofeng Meng, Zhihui Du
Astronomy is well recognized as big data driven science. As the novel observation infrastructures are developed, the sky survey cycles have been shortened from a few days to a few…
AstroServ: Distributed Database for Serving Large-Scale Full Life-Cycle Astronomical Data
Chen Yang, Xiaofeng Meng, Zhihui Du +6
In time-domain astronomy, STLF (Short-Timescale and Large Field-of-view) sky survey is the latest way of sky observation. Compared to traditional sky survey who can only find astro…
Data Management in Time-Domain Astronomy: Requirements and Challenges
Chen Yang, Xiaofeng Meng, Zhihui Du +2
In time-domain astronomy, we need to use the relational database to manage star catalog data. With the development of sky survey technology, the size of star catalog data is larger…
A Frequency Scaling based Performance Indicator Framework for Big Data Systems
Chen Yang, Zhihui Du, Xiaofeng Meng +2
It is important for big data systems to identify their performance bottleneck. However, the popular indicators such as resource utilizations, are often misleading and incomparable…
Acceleration of low-latency gravitational wave searches using Maxwell-microarchitecture GPUs
Xiangyu Guo, Qi Chu, Shin Kee Chung +2
Low-latency detections of gravitational waves (GWs) are crucial to enable prompt follow-up observations to astrophysical transients by conventional telescopes. We have developed a…
