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 ||
