The NextGen 1.7 Public Workshop, held on 6 November 2025 at CERN, brought together members of the Next Generation Triggers (NGT) project to share progress and discuss future directions within Task 1.7: Common Software Developments for Heterogeneous Architectures.

Led by Axel Naumann , Task 1.7 focuses on developing techniques to efficiently use heterogeneous computing resources—CPUs, GPUs, and FPGAs—in preparation for the High-Luminosity LHC era. The goal is to ensure that software frameworks and Monte Carlo generators make optimal use of all available resources across single and multi-node systems.

Throughout the morning, researchers presented recent advances in several core areas:

Fast ML Inference – Sanjiban Sengupta.

Memory Layouts and Data Structures – Oliver Gregor Rietmann.

Scheduling – Eric Cano.

Programming Languages and Frameworks – Mateusz Jakub Fila.

Hardware Acceleration for Monte Carlo Event Generation – Daniele Massaro.


In his closing remarks, Axel Naumann thanked all participants and attendees for their contributions and engagement, emphasizing how each effort helps advance the shared goal of NGT. From memory optimization to hardware acceleration, the developments presented show how innovation across CERN and partner institutes is paving the way for more efficient and unified computing frameworks for the HL-LHC era.
