The fifth edition of ESPM2 workshop, being proposed to be held as a full-day meeting with the Supercomputing (SC'2020) conference in Atlanta, Georgia focuses on programming models and runtimes for extreme scale systems. Next generation architectures and systems being deployed are characterized by high concurrency, low memory per-core, and multiple levels of hierarchy and heterogeneity. These characteristics bring out new challenges in energy efficiency, fault-tolerance and, scalability. It is commonly believed that software has the biggest share of the responsibility to tackle these challenges. In other words, this responsibility is delegated to the next generation programming models and their associated middleware/runtimes. This workshop focuses on different aspects of programming models such as task-based parallelism (Charm++, OCR, Habanero, Legion, X10, HPX, etc), PGAS (OpenSHMEM, UPC, CAF, Chapel, UPC++, etc.), BigData (Hadoop, Spark, Dask etc), Machine Learning (NVIDIA RAPIDS, Scikit-learn etc.), Deep Learning (Caffe, Microsoft CNTK, Google TensorFlow, Facebook PyTorch), directive-based languages (OpenMP, OpenACC) and Hybrid MPI+X, etc. It also focuses on their associated middleware (unified runtimes, interoperability for hybrid programming, tight integration of MPI+X, and support for accelerators/FPGAs) for next generation systems and architectures.

The ultimate objective of the ESPM2 workshop is to serve as a forum that brings together researchers from academia and industry working in the areas of programming models, runtime systems, compilation and languages, and application developers.

ESPM2 2020 will be held as a full day workshop in conjunction with the SuperComputing (SC 2020), on Wednesday November 11th in Atlanta, Georgia, USA.


ESPM2 2020 welcomes original submissions in a range of areas, including but not limited to:

  • New programming models, languages and constructs for exploiting high concurrency and heterogeneity
  • Experience with and improvements for existing parallel languages and run-time environments such as:
    • MPI
    • PGAS (OpenSHMEM, UPC, CAF, Chapel, UPC++, etc.)
    • Directive-based programming (OpenMP, OpenACC)
    • Asynchronous Task-based models (Charm++, OCR, Habanero,
    • Legion, X10, HPX, etc)
    • Hybrid MPI+X models
    • BigData (Hadoop, Spark, Dask etc.)
    • Machine Learning (NVIDIA RAPIDS, Scikit-learn etc.), and
    • Deep Learning (Microsoft CNTK, TensorFlow, PyTorch)
  • Parallel compilers, programming tools, and environments
  • Programming environments for heterogeneous multi-core systems and accelerators such as KNL, OpenPOWER, ARM, GPUs, FPGAs, MICs, and DSPs

Title: Extreme Scale Programming with Novel Programming Methods

As extreme scale platforms, both for HPC and Cloud Computing, continue the decade long shift towards an architectural configuration that greatly favors local, small memory footprint computation, it is time to consider spending a small amount of these excellent local compute and memory resources on efforts to increase programmability and provide for a wider programmer base. This is especially the case for computations which inherently require either significant non-local interaction and/or large memory footprints. This talk will highlight the work of the speaker and others on computational techniques using novel approaches to remote data manipulation, such as Actors and Conveyors; using techniques that employ aggregation and asynchrony; in programming languages such as JavaScript and Rust.

Invited Talks

  • "Programming modern GPU supercomputersa", Jeff Hammond, Intel, USA
  • "Automating Massively Parallel Heterogeneous Computing for Python Programmers", Vivek Sarkar, Georgia Institute of Technology, USA
  • "A Parallel Execution Model for Exascale non von Neumann Memory-Centric Architectures", Thomas Sterling, Indiana University, USA
