Adaptive optics system generally consist of three core components: deformable mirrors, wavefront sensors and real time computers (RTC). In this talk we will focus on the RTC in particular on the one we are currently working on for METIS.[[BR]]What is the task of the RTC in the control loop and what can the RTC actually 'see'? What are the main data products and which computational steps does it have to do to produce them? What is a mode? How fast does the RTC have to be and what does 'Real Time' mean? How did we get the RTC to be fast enough and what are the main differences between a central processing unit (CPU) and a graphics processing unit (GPU)?[[BR]][[BR]]We will address these and other questions in a graphic way.[[BR]][[BR]]Presentation: English[[BR]]Slides: English[[BR]]Questions: German, English ||29 || '''25.09.2023''' || '''Hugo Coppejans''' || '''Accelerated computing using GPUs with applications in Adaptive Optics for METIS SCAO'''[[BR]][[BR]]Astronomy has always been a data driven field, but as telescopes become more advanced, the amount of data is growing at an unprecedented rate. The Single-Conjugate Adaptive Optics (SCAO) subsystem for METIS, a first light instrument for the upcoming Extremely Large Telescope (ELT) telescope, generates more than 20TB of data every night. To be able to parse all of this data, accelerated computing is crucial. [[BR]][[BR]]This talk will give an overview and delve a bit deeper into accelerated computing using GPUs, and how it will be used to operate the adaptive optics (AO) system for METIS at the ELT. This talk will focus on explaining GPU-accelerated coding while giving real examples of how it is being used in our AO prototype.[[BR]][[BR]]Presentation: English[[BR]]Slides: English[[BR]]Questions: German, English || 30 30 || 02.10.2023 || -- || -- || 31 31 || 09.10.2023 || Institutional Review || ||
