WACCPD 2018 - FIFTH Workshop on Accelerator Programming using Directives (WACCPD)

Current hardware trends lead to ever more complex compute node architectures offering multiple, heterogeneous levels of massive parallelism. As a result the ‘X’ in MPI +X demands more focus. A node in a future exascale system is expected to consist of GPU-like accelerators combined with processor architectures of other types. In order to exploit the maximum available parallelism out of such systems, we are in dire need of sophisticated programming approaches that can provide scalable as well as portable solutions without compromising on performance. The expectation from the scientific community is that such solutions should allow programmers to maintain a single code base whenever possible and to avoid requiring maintaining and debug multiple versions of the same code.
Raising the abstraction of the code is one of the effective methodologies to reduce the burden on the programmer. At the same time such a methodology will require a heroic compiler to be designed. Software abstraction-based programming models such as OpenMP and OpenACC have been serving this purpose over the past several years. These programming models address the ‘X’ component by providing programmers high-level directive-based approaches to accelerate and port scientific applications to heterogeneous platforms. Such programming paradigms played a decisive role in establishing heterogeneous node architectures as a valid choice for a multitude of HPC workloads.
The focus of this workshop is to explore this ‘X’ component in a hybrid MPI +X programming approach. We are looking forward to technical papers discussing innovative high-level language features and their (early prototype) implementations needed to address hierarchical heterogeneous systems, stories and lessons learnt while using directives to migrate scientific legacy code to parallel processors, state-of-the-art compilation and runtime scheduling techniques, techniques to optimize performance, mechanisms to keep communication and synchronization efficient.
We are looking forward to hosting WACCPD at SC18. In the past four years of this workshop, WACCPD has been one of the major forums at SC to bring together programming model users, developers, and tools community to share knowledge and experiences to tackle emerging complex parallel computing systems.
Topics of interest for workshop submissions include (but are not limited to):
• Programming experiences porting applications in any scientific domain
• Compiler and runtime support for current and emerging architectures (e.g. heterogeneous architectures, low-power processors
• Experiences in implementing compilers for accelerator directives on newer architectures
• Language-based extensions and its prototype for directive-based programming model
• Abstract handling of complex/heterogeneous memory hierarchies
• Extensions to and shortcomings of current directives for heterogeneous systems
• Comparisons against lower or higher level abstractions
• Application performance evaluation, validation and lessons learnt
• Modeling, verification and performance analysis tools
• Auto-tuning and optimization strategies
• Parallel computing using hybrid programming paradigms (e.g. MPI, OpenMP, OpenACC, OpenSHMEM)
• Asynchronous execution and scheduling (task based approaches)
• Scientific libraries interoperability with directive based models
Important Deadlines
• Submission Deadline: September 07, 2018
• Author notification: September 30, 2018
• Workshop Ready Deadline: October 10, 2018
• Camera Ready papers due: December, 2018 AoE
Paper Submission Guidelines
• Papers should be submitted electronically via the SC18 Submission Page (https://submissions.supercomputing.org).
• They must follow the Springer LNCS format. Submissions are limited to 20 pages. The 20-page limit includes figures, tables, and appendices, but does not include references, for which there is no page limit.
• Submitted papers should not have appeared in or be under consideration for a different workshop, conference or journal.
• In submitting the paper, the authors acknowledge that at least one author of an accepted submission will register for and attend the workshop.
Reproducibility
Reproducibility has already been well adopted within the SC Papers program, with about 40% of submissions and 50% of accepted papers containing a reproducibility appendix.
Moving in this direction, reproducibility is being strongly encouraged by submitters to SC workshops as well.
Please follow SC17 tech paper guidelines for instructions on reproducibility. Templates are available. http://sc17.supercomputing.org/program/technical-p...
Please use additional 2 pages beyond the 20-page limit to add appendix information. These 2 pages will be part of your full technical paper during the review process. Once your paper is accepted, you will be able to lift these pages off the paper to be published by Springer and add the information to Zenodo or an associated capsule of Code Ocean or anything else you would like to use (pls avoid using personal webpages for this step).
You will then be asked to add a blurb or “artifacts available” in your paper to be published and point readers to wherever you have added information regarding reproducibility.
This way information on reproducibility is yours and will not become part of your Springer published proceedings.
For an example on how to go about this, please refer to any publication in
https://collegeville.github.io/sc-reproducibility/... and scroll down to look for the 2 pages of information on reproducibility.
• A paper cannot be disqualified based on information provided or not provided in this appendix, nor if the appendix is not available.
• The availability and quality of an appendix can be used in ranking a paper. In particular, if two papers are of similar quality, the existence and quality of the appendices can be part of the evaluation process.
• In order to be considered for the Best Paper Award, the authors must submit an Artifact Description appendix.
• If the authors are not able to add such details, they must add a note that says, why not?
