[hpc-announce] Deadline extended for 2026 HPC on Heterogeneous Hardware (H3, part of ISC 2026)

[ Apologies if you received multiple copies of this email. ]

Dear colleagues,

we'd like to announce a deadline extension for 2026 H3 Workshop:
HPC on Heterogeneous Hardware (co-located with ISC HPC 2026 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.
