Call for Papers:
========================================

EuroMPI 2026 will continue to focus on advancing the ubiquitous Message Passing Interface (MPI) model and specification for parallel programming. It will also encompass extensions and alternative interfaces for high-performance heterogeneous and hybrid systems, benchmarks, tools, parallel I/O, fault tolerance, and parallel applications using MPI and other interfaces.

EuroMPI 2026 will be hosted by TU Wien, in the centre of Vienna, Austria and will be co-located with IWOMP 2026 (October 7 - October 9, 2026), with joint tutorials, and opportunities for interaction between the two communities.

Through the presentation of papers, posters, and invited talks, the meeting will provide ample opportunities for attendees to interact, share ideas, and exchange experiences, contributing to the advancement of message passing and related parallel programming paradigms.

We invite high-quality, full and short paper submissions on all topics related to message-passing parallel programming with MPI and related or competing models. Topics of interest include, but are not limited to:

- Implementation Issues and Algorithms: Efficient and scalable implementations of message-passing constructs.
- Architectures and systems: Towards exascale computing, efficient use of accelerators and other features of modern, large-scale systems, and hardware-software interaction.
- Message Passing for accelerator-based compute architectures, including multi-GPU, TPU, and AI-accelerator systems.
- Programming models and paradigms related to MPI targeting large-scale, parallel, distributed memory systems, hierarchical and hybrid models, and partitioned global address space (PGAS) models.
- Extensions to and shortcomings of MPI: alternative interfaces and solutions.
- Parallel I/O: New mechanisms and optimizations for (MPI-)I/O.
- Hybrid and heterogeneous programming with MPI and other interfaces.
- Message passing interface support for data-intensive parallel applications.
- Fault tolerance in message-passing implementations and systems.
- MPI parallel programming in clouds and non-dedicated systems.
- Performance evaluation for MPI and MPI-based applications.
- Automatic performance tuning of applications and implementations.
- Verification of message-passing applications and protocols.
- Applications using advanced message passing, in particular in computational science and scientific computing.
- Parallel algorithms in the message-passing paradigm.
- Interactions between the message-passing library and runtime systems.
- Use of MPI in Artificial Intelligence (AI) and Large Language Models (LLM) and its challenges
- Competing standards: Integration with and comparison to competing industry standards (e.g., NCCL, RCCL)
