Applications and Techniques for Fast Machine Learning in Science
/ Deiana, Allison McCarn (Southern Methodist U.) ; Tran, Nhan (Fermilab ; Northwestern U. (main)) ; Agar, Joshua (Lehigh U. (main)) ; Blott, Michaela (Xilinx, Dublin) ; Di Guglielmo, Giuseppe (Columbia U. (main)) ; Duarte, Javier (UC, San Diego) ; Harris, Philip (MIT) ; Hauck, Scott (George Washington U. (main)) ; Liu, Mia (Purdue U.) ; Neubauer, Mark S. (Illinois U., Urbana) et al.
In this community review report, we discuss applications and techniques for fast machine learning (ML) in science -- the concept of integrating power ML methods into the real-time experimental data processing loop to accelerate scientific discovery. The material for the report builds on two workshops held by the Fast ML for Science community and covers three main areas: applications for fast ML across a number of scientific domains; techniques for training and implementing performant and resource-efficient ML algorithms; and computing architectures, platforms, and technologies for deploying these algorithms.

The Phase-I Trigger Readout Electronics Upgrade of the ATLAS Liquid Argon Calorimeters
/ Aad, G. (Marseille, CPPM) ; Akimov, A.V. (CERN ; LPI, Moscow (main)) ; Al Khoury, K. (Nevis Labs, Columbia U.) ; Aleksa, M. (CERN) ; Andeen, T. (Arizona U.) ; Anelli, C. (Victoria U.) ; Aranzabal, N. (CERN) ; Armijo, C. (Arizona U.) ; Bagulia, A. (Lebedev Inst.) ; Ban, J. (Nevis Labs, Columbia U.) et al.
The Phase-I trigger readout electronics upgrade of the ATLAS Liquid Argon calorimeters enhances the physics reach of the experiment during the upcoming operation at increasing Large Hadron Collider luminosities. The new system, installed during the second Large Hadron Collider Long Shutdown, increases the trigger readout granularity by up to a factor of ten as well as its precision and range. [...]
