Welcome

The 20th International Workshop on Algorithms, Models and Tools for Parallel Computing on Heterogeneous Platforms (HeteroPar 2022) will be held on August 23, 2022 as a full-day workshop at the University of Glasgow, Scotland, United Kingdom.
For the 13th time, HeteroPar is organized in conjunction with the Euro-Par annual series of international conferences dedicated to the promotion and advancement of all aspects of parallel computing.

Workshop scope

Heterogeneity is emerging as one of the most profound and challenging characteristics of today's parallel environments. From the macro level, where networks of distributed computers, composed of diverse node architectures, are interconnected with potentially heterogeneous networks, to the micro level, where deeper memory hierarchies and various accelerator architectures are increasingly common, the impact of heterogeneity on all computing tasks is increasing rapidly. Traditional parallel algorithms, programming environments and tools, designed for legacy homogeneous multiprocessors, will at best achieve a small fraction of the efficiency and the potential performance that we should expect from parallel computing in tomorrow's highly diversified and mixed environments. New ideas, innovative algorithms, and specialized programming environments and tools are needed to efficiently use these new and multifarious parallel architectures. The workshop is intended to be a forum for researchers working on algorithms, programming languages, tools, and theoretical models aimed at efficiently solving problems on heterogeneous platforms.


Topics to be covered include but are not limited to:

  • Heterogeneous parallel programming paradigms and models

  • Languages, libraries, and interfaces for heterogeneous parallel programming models

  • Performance models and their integration into the design of efficient parallel algorithms for heterogeneous platforms

  • Parallel algorithms and scheduling for heterogeneous and/or hierarchical systems, including manycores and hardware accelerators (e.g. FPGAs, GPUs, AI accelerators)

  • Parallel algorithms for efficient problem solving on heterogeneous platforms (e.g. numeri- cal linear algebra, nonlinear systems, fast transforms, computational biology, data mining, artificial intelligence, multimedia)

  • Applications and software engineering for heterogeneous parallel systems

  • Algorithms, models and tools for energy and/or multi-objective optimization on heterogeneous platforms

  • Integration of parallel and distributed computing on heterogeneous systems

  • Experience of porting parallel software from supercomputers to heterogeneous platforms

  • Fault tolerance of parallel computations on heterogeneous platforms

  • Algorithms, models and tools for grid, desktop grid, cloud, and green computing that include heterogeneous computing aspect

Authors are encouraged to submit original, unpublished research or overviews on Algorithms, Models and Tools for Parallel Computing on Heterogeneous Platforms, namely addressing the topics referred above.

Title: Domain-specific compiler architecture for today’s accelerators and tomorrow’s

Abstract: Domain-specific languages enable the compiler to understand more about what you are trying to do. If we get it right, DSLs enable us, at the same time, both to boost programmer productivity and also to automate sophisticated domain-specific optimisations that would be hard to do by hand - yet are essential to achieving efficient use of the hardware. DSLs are power tools for performance programming - and for effective exploitation of accelerators. This talk will offer some of our experience in building DSLs that deliver productivity, performance and performance portability. DSLs enable us to find the right representation for a program so that complex optimisations turn out to be easy – so DSLs demand that we pay attention to compiler “architecture”. I will try to map out how to design domain-specific compiler architecture – and set out a vision for a future where we work together to build on representations that are common across different DSLs, and which support the growing diversity of high-performance hardware available.


Short bio: Paul Kelly leads the Software Performance Optimisation group at Imperial College London. His research focus is domain-specific program optimisation, leading to close engagement with colleagues in computational science, robotics and computer vision. This talk covers joint work with many such collaborators.
