摘要:

切伦科夫望远镜阵列(CTA)天文台必须能够对可变和瞬态源发出快速警报,以最大限度地提高科学回报。这将通过CTA观测站的一个关键系统-实时分析管道来完成。报警系统的延迟和灵敏度要求是一个挑战,因为预计的数据流量很大,在0.5和8 GB/s之间。因此,设想了对这种高吞吐量计算服务进行优化的大量努力,以及RTA应在现场进行的额外约束(作为望远镜辅助基础设施的一部分)。在这项工作中,RTA管道的功能设计。

英文摘要:

The Cherenkov Telescope Array (CTA) Observatory must be capable of issuing fast alerts on variable and transient sources to maximize the scientific return. This will be accomplished by means of a Real-Time Analysis (RTA) pipeline, a key system of the CTA observatory. The latency and sensitivity requirements of the alarm system impose a challenge because of the large foreseen data flow rate, between 0.5 and 8 GB/s. As a consequence, substantial efforts toward the optimization of this high-throughput computing service are envisaged, with the additional constraint that the RTA should be performed on-site (as part of the auxiliary infrastructure of the telescopes). In this work, the functional design of the RTA pipeline is presented.
