[ Apologies if you received multiple copies of this email. ] Dear colleagues, we'd like to announce a deadline extension for 2025 H3 Workshop: HPC on Heterogeneous Hardware (co-located with ISC HPC 2025 conference in Hamburg, Germany) The HPC on Heterogeneous Hardware (H3) Workshop is intended as an in-person event. It provides a platform for novel work on algorithmic research, software library design, programming models, and workflow development for increasingly heterogeneous hardware platforms. These span from ARM and RISC-V processors featuring long-vector extensions through GPU-accelerated and chiplet-rich systems to architectures deploying special function units, FPGAs, or specialized deep learning processors. The workshop will be composed of a well-balanced mix of invited talks, peer-reviewed conference contributions, and a panel bringing together worldwide experts in heterogeneous computing. Scope - - - The workshop's scope includes a few thematic areas that currently dominate the efforts of the community in attempt to harness the complexities of the heterogeneous platforms. This year, these include the following topics of interest: - Heterogeneity in programming models including language solutions and DSL-friendly middleware libraries. - Heterogeneous workloads that rely on convergence of scientific modeling, data analytics, and scientific AI/ML data models including surrogates - Heterogeneity in data representation including hierarchical, randomized, compressive, and mixed-precision methods - Post-Moore computing challenges and paradigm shifts extending accelerator-based, FPGA, and chiplet platforms Topics of Interest - - - - - - - - - A more specific list of topics of interest to focus the submissions and draw a variety of speakers and invite broad participation of attendees will be the following: - Heterogeneous algorithms that scale not just in terms of the system size but across diverse hardware kinds. - Heterogeneity in data approaches that incorporate multi-precision storage and compute including data compression as well as hierarchical and randomized methods. - Software systems and libraries that support heterogeneous hardware and networking including in-memory or in-network computing. - Programming models and tools that incorporate heterogeneity of both on-node compute and cross-node networking.
