    Porting and Accelerating LSQR-based Applications with OpenACC

    The Gaia mission is an extraordinarily large project launched by the European Space Agency (ESA) in 2013 to create the most precise 3D map of the Milky Way, describing the position, motion, and properties of nearly two billion objects. The Gaia Astrometric Verification Unit–Global Sphere Reconstruction (AVU–GSR) Parallel Solver derives the positions and proper motions of primary stars in the Milky Way observed with the Gaia satellite.

    Accelerating Fast Fluid Dynamics Simulations with OpenACC

    Understanding turbulent fluid flows lies at the heart of such versatile domains as climate, health, and energy. Modern methods used in flow simulations have yet to reach their efficiency limits in providing fast, high-resolution predictions. To answer outstanding questions about the nature of turbulence requires massive computing power and innovative  methods designed with computational efficiency at their core.

    Accelerating Simulations of Turbulent Compressible Flows with OpenACC

    The field of computational fluid dynamics (CFD) struggles with challenges to resolve computational complexity and cost of the simulations. Executing the operations over large fine meshes at small timesteps requires the algorithms to be designed with parallel efficiency at their core.

    Developing and Running Complex Applications with Compiler Directives

    Climate scientists writing code have often been weary of multithreading, both on CPU and GPU, due to some aspect of non-reproducibility, across machines and implementations. However, the current state of the ICON model, with about 2 Million lines of code written since 2001, is living proof that porting legacy software to GPUs can be made possible with compiler directives.

    Beyond Directives: Unveiling the Latest Trends in Accelerator Programming at WACCPD 2022

    The number of available accelerators featured in high-performance computing (HPC) systems is rapidly increasing. As this trend continues, compute nodes are expected to become more heterogeneous and complex than ever before. Consequently, applications will require the right set of programming models and tools to program these systems to take full advantage of their massive performance. Thus, it is important to answer the question of how to provide performance, portability, and programmability in current and future HPC systems and applications.

    Announcing OpenACC 3.3 at SC22!

    Another year has passed since the release of OpenACC 3.2 and, once again, the technical committee has been hard at work maintaining and improving the OpenACC specification. As a committee we decided several years ago that an annual release cadence is the best way to ensure that improvements are delivered in a thoughtful and timely manner.

    Announcing OpenACC 3.2

    It’s been a year since we announced the completion of OpenACC 3.1 and I’m pleased to announce that we have now completed version 3.2. For the past several OpenACC releases we have taken the approach of releasing on an annual cadence so that our releases aren’t held up by unfinished business and so that our implementers don’t have to read and understand monolithic changes upon release. It’s sometimes heard on OpenACC technical calls that we’d rather miss a release to get the feature right than hold up releasing things that are complete just to finish one more thing.
