8th edition (2026)

Arm HPC User Group

The Arm HPC User Group (AHUG) annual workshop gathers users, developers, system operators, researchers, and technology providers involved in the growing Arm for HPC ecosystem.

Co-located with ISC High Performance conference (https://isc-hpc.com)

Call for Papers

AHUG welcomes talk proposals from users, developers, system operators, researchers, and technology providers working across the Arm HPC ecosystem.

This is a workshop without proceedings. Submissions are for workshop presentations and community discussion.

Topics

  • Programming for Arm-compatible platforms
  • Code strategies to vectorization using SVE or SME
  • Developer Tools for Arm (including for SVE)
  • Experiences running workloads on CPU-only or Accelerated Arm-based systems
  • Co-design and simulation-based Arm architecture exploration
  • Arm for the Intelligent Computing Continuum, from Edge to Dacatentre
  • Community actions to advance Arm HPC software ecosystem
