EuroMPI/USA 2025 will continue to focus on advancing the ubiquitous Message Passing Interface (MPI) model and specification of 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.

Submission Guidelines

All papers must be original and not simultaneously submitted to another journal or conference. The following submission categories are welcome:

• Full papers describing original research on topics listed below. Full papers should be between 12 and 16 pages, including figures and tables but excluding references.
• Short papers may present work in progress or positions and may contain between 6 and 9 pages, including figures and tables but excluding references.
• Posters presenting work in progress and experiences in using and developing MPI implementations and applications are welcome. Poster abstracts should contain no more than 2 pages.

List of Topics

• 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, 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, partitioned global address space (PGAS) models.
• Extensions to and shortcomings of MPI: alternative interfaces and solutions.
• New, parallel (MPI-)I/O mechanisms optimizations.
• 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
• Integration and comparisons with competing industry standards (e.g., NCCL, RCCL)
