*IWOMP 2017 - 13th International Workshop on OpenMP* September 21-22, 2017 Stony Brook, NY, USA https://you.stonybrook.edu/iwomp2017/ *Background* For many years, OpenMP has provided a very rich and flexible programming model for shared memory architectures. OpenMP 4.0 is a major advance that adds new forms of parallelism: device constructs for accelerators, SIMD constructs for vector units, and several significant extensions for work-sharing and task-based parallelism. OpenMP 4.5 further extends OpenMP for use with today's complex heterogeneous architectures. 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 discuss issues, trends, recent research ideas, and results related to OpenMP. We solicit submissions of unpublished technical papers detailing innovative, original research and development related to OpenMP. *Topics* All topics related to OpenMP are of interest, including OpenMP performance analysis and modeling, OpenMP performance and correctness tools, proposed OpenMP extensions, and OpenMP applications in any domain (e.g., scientific and numerical computation, video games, computer graphics, multimedia, information retrieval, optimization, text processing, data mining, finance, signal and image processing, and machine learning). Advances in technologies, such as new kinds of memory, deep memory hierarchies, multi-core processors, and support in OpenMP for devices (accelerators such as GPGPUs, DSPs and FPGAs), Multiprocessor Systems on a Chip (MPSoCs), 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. IWOMP 2017 particularly solicits submissions in these areas as well as ones that discuss how to apply OpenMP to additional models of parallelism such as event loops. *Paper Submission and Registration* Submitted papers for review should be limited to 12 pages and follow LNCS guidelines. Submission deadline is April 28, 2017 (AOE). Authors of accepted papers will be asked to prepare a final paper of up to 15 pages. As in previous years, IWOMP 2017 will publish formal proceedings of the accepted papers in Springer Verlag's LNCS series. *Important Dates* Paper Submission Deadline: April 28, 2017 Notification of acceptance: May 25, 2017 Deadline for final version: June 8, 2017 *Organizers* General Chair: - Abid Malik, Brookhaven National Laboratory, USA Program Committee Co-chairs: - Bronis R. de Supinski, Lawrence Livermore National Laboratory, USA - Stephen Olivier, Sandia National Laboratories, USA
