IWOMP 2025 - CALL FOR PAPERS

• IWOMP 2025
• 21th International Workshop on OpenMP
• October 1-3, 2025+ The University of North Carolina at Charlotte, NC, USA
• https://www.iwomp.org
• Submission deadline: Friday, May 16 2025 (AoE)

The International Workshop on OpenMP (IWOMP) is the annual workshop dedicated to the promotion and advancement of all aspects of parallel programming with OpenMP. This pioneering workshop has been attracting an international audience of leading academic and industrial experts since 2005 and is the premier forum to present and discuss issues, trends, recent research ideas, and results related to parallel programming with OpenMP.

We solicit quality submissions of unpublished technical papers that detail innovative, original research and development related to OpenMP.

IWOMP 2025 will be hosted by the University of North Carolina at Charlotte in Charlotte, North Carolina, USA and will be co-located with EuroMPI 2025 (https://eurompi.org/).

BACKGROUND

As computing hardware has evolved from simple cores to advanced SIMD units, deeper memories, and heterogeneous computing, the OpenMP API has also evolved and extended its application interface to harness new capabilities throughout the spectrum of hardware advances. The 5.0, 5.1 5.2 and 6.0 versions of the OpenMP specification have established the OpenMP API as the leading programming language for on-node heterogeneous parallelism that supports all versions of the C/C++ and Fortran base programming languages.

Advances in technologies, such as multicore processors and OpenMP devices (accelerators such as GPGPUs, DSPs or FPGAs), Multiprocessor Systems on a Chip (MPSoCs), and recent developments in the OpenMP API itself (e.g., metadirectives and variants for selecting device- and architecture-specific directives) present new opportunities and challenges for software and hardware developers. Recent advances in the C, C++ and Fortran base languages also offer interesting opportunities and challenges to the OpenMP programming model.

Theme for 2025: OpenMP: Balancing Productivity and Performance Portability

The OpenMP API has been instrumental in advancing parallel programming, enabling portability across both traditional and emerging computing systems. As the standard continues introducing new capabilities, the OpenMP API continues to evolve, offering solutions to the growing complexity of high-performance computing (HPC) environments. The workshop welcomes topics on how OpenMP API strikes a balance between ease of use and maximizing performance, particularly in the context of heterogeneous systems, exascale computing, and real-time workloads.

TOPICS

The topics include but are not limited to the following:

• Accelerated computing and offloading to devices
• Applications (in any domain) that rely on OpenMP
• Data mining and analysis or text processing and OpenMP
• Machine learning and OpenMP
• Memory model
• Memory policies and management
• Performance analysis and modeling
• Performance portability
• Proposed OpenMP extensions
• Runtime environment
• Scientific and numerical computations
• Tasking
• Tools
• Vectorization

SUBMISSIONS

Submitted papers for review should be limited to 12 pages (not counting references). Authors of accepted papers will be asked to prepare a final paper of up to 15 pages (including references).

• Submission deadline: Friday, May 16, 2025 (AoE)
• Acceptance Notifications: Friday, July 11, 2025 (AoE)
• Camera Ready Copy Deadline: Friday, July, 25 2025 (AoE)
