Call for papers

First Annual Workshop on Programming Model Alternatives to Message Passing (PMAMP)-2017 September 25, 2017, Chicago, IL in collaboration with EuroMPI/USA 2017

https://memani1.github.io/pmamp17/

Overview:

Message-passing programming models have dominated high-performance computing (HPC) for the past quarter century. With the continued breakdown of the (uniform) communicating sequential processors abstract machine model, many researchers have questioned the continued viability of message passing as a model for direct, application-level interaction. Recent years have seen an explosion of new paradigms in programming models for distributed-memory computing. The move to the next generation of HPC platforms presents a wider variety of challenges than ever before, that include the increased need for asynchrony, increased heterogeneity and performance non-uniformity, decreased hardware reliability and increased failure rates, increased hardware diversity, and the maintainability of increasingly complex scientific code bases.

This workshop proposes to promote a dialogue between researchers who work on extensions or augmentations to message-passing models (the “evolutionary” crowd) to alternative programming models and to expose those who develop fundamentally different programming models (the “revolutionary” crowd) to the recent advances in message-passing programming models. It aims to help understand the relative importance of the concerns these new approaches address. The workshop seeks to garner a better understanding of key motivations for alternative programming models, key insights from advances in message passing (and how they can be applied to alternative models), and key opportunities for collaboration between researchers on both sides.

Topics:

We solicit preliminary work on programming models that offer extensions or alternatives to message passing, with emphasis on addressing emerging concerns in high performance computing (HPC), including topics relating to (but are not restricted to) the following:

* Asynchrony * Heterogeneity * Performance non-uniformity * Fault-tolerance and resilience * Performance portability: a posteriori adaptability (“one code for many machines”) in situ adaptability (reactive and dynamic runtime system solutions) * Maintainability (particularly in the presence of these other challenges) * Testability and debuggability (particularly in the presence of these other challenges) * Experimental comparative results (particularly with emphasis on overall time-to-solution) * Relevance of alternate programming models to particular scientific kernels

Also, we solicit position papers on analyzing the importance (or lack thereof) of the above topics for the future of HPC, again with emphasis on the need (or lack thereof) to address these concerns at the programming model level (thus, for instance, arguments for why the challenges can be addressed at other levels of the software stack without programming model intervention will also be considered).
