OpenMP: Portable Multi-level Parallelism on Modern Systems

The International Workshop on OpenMP (IWOMP) is an annual workshop dedicated to the promotion and advancement of all aspects of parallel programming with OpenMP. It is the premier forum to present and to 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 We solicit quality submissions of unpublished technical papers that detail innovative, original research and development related to OpenMP.


As computing hardware has evolved from simple core reproduction to advanced SIMD units, deeper memories, and heterogeneous computing, OpenMP has also evolved and extended its application interface to harness new capabilities throughout the spectrum of hardware advances. New features and extensions of the OpenMP 5.0 interface have taken major steps to provide control of the parallelism within the paradigms and complexity of modern C/C++ and Fortran programming languages. OpenMP enhancements range from operational aspects deep within the vector execution units, up through the cores and memory, and beyond, to offloading across accelerator devices.

Advances in technologies, such as multi-core processors and OpenMP devices (accelerators such as GPGPUs, DSPs or FPGAs), Multiprocessor Systems on a Chip (MPSoCs), and recent developments in OpenMP 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.


All topics related to parallelism in OpenMP are of interest, including:

  • Vectorization
  • Offloading to Devices
  • Memory Model
  • Memory Policies (Affinity) and Management
  • Tasking
  • Affinity
  • Runtime Environment
  • Performance Analysis and Modeling
  • Tools
  • Proposed OpenMP Extensions
  • OpenMP Applications in any Domain
    • Scientific and numerical computations, video games, computer graphics, multimedia, information retrieval, optimization, text processing, data mining, finance, signal and image processing and machine learning.

Paper Submission and Registration

Update: Virtual presentations will be permitted (but full registration is required) if an accepted author is prevented from attending due to COVID-19 related travel restrictions.

Submitted papers for review should be limited to 12 pages (not counting references) and follow LNCS Guidelines.

Authors of accepted papers will be asked to prepare a final paper of up to 15 pages (including references). As in previous years, IWOMP 2020 will publish formal proceedings of the accepted papers in Springer’s series.
