H3W2025: 4th Workshop on HPC on Heterogeneous Hardware (H3) 2025 Congress Center Hamburg (CCH) Hamburg, Germany, June 10, 2025

The HPC on Heterogeneous Hardware (H3) Workshop is intended as an in-person event in Hamburg, Germany. It does so by providing a platform for pioneering work on algorithmic research, software library design, programming models, and workflow development for increasingly heterogeneous hardware. In the workshop context, such hardware spans from ARM and RISC-V processors featuring long-vector extensions through GPU-accelerated systems to architectures deploying special function units, FPGAs, or deep learning processors. The workshop will compose of a well-balanced mix of invited talks, peer-reviewed conference contributions, and a panel bringing together worldwide experts in heterogeneous computing.

Submission Guidelines

Papers will be reviewed and should include abstract, keywords, the e-mail address of the corresponding author, and must not exceed 10 pages, including double-column text, tables, figures, and references at a main font size no smaller than in IEEE conference style. Submission of a paper should be regarded as a commitment that, should the paper be accepted, at least one of the authors will register and attend the workshop to present the work. All papers must be original and not simultaneously submitted to another journal or conference. Accepted papers will be allowed extra pages to address reviewer comments. The following paper categories are welcome:

List of Topics

• algorithms for heterogeneous hardware
• mixed precision for heterogeneity
• heterogeneous software support
• programming for heterogeneity
