Data pubblicazione: | 2014 | Titolo del volume in cui è pubblicato il poster: | Ground-based and Airborne Telescopes V | Curatore/i del volume in cui è pubblicato il contributo: | Stepp, Larry M.; Gilmozzi, Roberto; Hall, Helen J. | Serie: | PROCEEDINGS OF SPIE | Numero: | 9145 | Da pagina:: | 91452X | Abstract: | The Cherenkov Telescope Array (CTA) observatory will be one of the biggest ground-based very-high-energy (VHE) γ- ray observatory. CTA will achieve a factor of 10 improvement in sensitivity from some tens of GeV to beyond 100 TeV with respect to existing telescopes. The CTA observatory will be capable of issuing alerts on variable and transient sources to maximize the scientific return. To capture these phenomena during their evolution and for effective communication to the astrophysical community, speed is crucial. This requires a system with a reliable automated trigger that can issue alerts immediately upon detection of γ-ray flares. 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 anticipated large data rate, between 0.5 and 8 GB/s. As a consequence, substantial efforts toward the optimization of highthroughput computing service are envisioned. For these reasons our working group has started the development of a prototype of the Real-Time Analysis pipeline. The main goals of this prototype are to test: (i) a set of frameworks and design patterns useful for the inter-process communication between software processes running on memory; (ii) the sustainability of the foreseen CTA data rate in terms of data throughput with different hardware (e.g. accelerators) and software configurations, (iii) the reuse of nonreal- time algorithms or how much we need to simplify algorithms to be compliant with CTA requirements, (iv) interface issues between the different CTA systems. In this work we focus on goals (i) and (ii). | Titolo del convegno: | Ground-based and Airborne Telescopes V | Luogo del convegno: | Montréal, Quebec, Canada | Periodo del convegno: | 22-27 June, 2014 | URI: | http://hdl.handle.net/20.500.12386/34772 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/9145/1/A-prototype-for-the-real-time-analysis-of-the-Cherenkov/10.1117/12.2054744.short https://api.elsevier.com/content/abstract/scopus_id/84922731099 |
