ParCo Mini Symposium

Mini Symposium: Is the Programming Environment Ready For Hybrid Supercomputers?

Call For Abstracts

The Mini-Symposium forms part of the International Conference on Parallel Computing (ParCo) to be held in Edinburgh, Scotland from 1-4 September 2015. The symposium runs from 3-4 September and will include invited and submitted talks.

Hybrid supercomputers are increasingly prevalent in the Top500 list, including large GPU-accelerated machines in Switzerland and the US. Future high end systems will be much more parallel with heterogeneous processing elements (e.g. GPU or MIC accelerators), more processors per node, more threads per processor, longer vector lengths and more complex memory hierarchies. A good programming environment (PE) is therefore essential to allow application developers to maximise programmability, ease porting, correctness-checking and tuning efforts and maintain performance-portability across a wide range of systems.

In this mini-symposium we will discuss the state-of-the-art in PEs for hybrid supercomputers from the perspectives of application specialists, tools developers and vendors, with a view to constructing a list of recommendations for future PE components and integration.

Specific areas of interest are:

• Use of high level programming models, especially directive-based ones like OpenACC and OpenMP Device Constructs
• "Message passing" techniques (MPI or PGAS) in environments with diverse memory spaces
• Development, performance analysis and debugging tools

A list of invited presentations includes:

• Intel
• NVIDIA
• CSCS, Switzerland
• Cray Inc.

A panel session will allow all participants to contribute to a gap analysis and recommendations for hybrid programming environments.

Call for Participation

Authors are invited to submit abstracts for the symposium which will be peer reviewed. Abstracts should be between 1-2 pages, in English and PDF format. A short abstract (up to 250 words) will be required soon after acceptance if not supplied along with the submission.

Authors with accepted submissions should register for the ParCo conference and will have the option to have a paper published in the ParCo proceedings.

Please see the symposium website (http://www.parco2015.org/programming-environment-ready-hybrid-supercomputers) for the latest information on the symposium and how to submit.

Important Dates:

• Original Abstract Submission Close: 5th July 2015
• Extended submission deadline: 15th July 2015
• Results of call for abstracts communicated to authors: 24th July 2015
• Mini-Symposium: Sep 4-5
