ExaMPI18 - Workshop on Exascale MPI 2018 Sunday November 11th, 2018 Dallas, TX, USA https://sites.google.com/site/exampiworkshop2018

Held in conjunction with SC18: The International Conference for High Performance Computing, Networking, Storage and Analysis

===========================================================

The MPI standard and its implementations have proved surprisingly scalable. Issues that hampered scalability have been addressed in the MPI 2.1 – 2.2 definition process, and continued into MPI 3.0 and 3.1. Thus MPI has been robust, and been able to evolve, without fundamentally changing the model and specification. For this and many other reasons MPI is currently the de-facto standard for HPC systems and applications. However, there is a need for re-examination of the message-passing model for extreme-scale systems characterized by asymptotically decreasing local memory and highly localized communication networks. Likewise, there is a need for exploring new innovative and potentially disruptive concepts and algorithms partially to explore other roads than those taken by the recently released MPI 3.1 standard. The aim of workshop is to bring together developers and researchers to present and discuss innovative algorithms and concepts in Message Passing programming models, in particular related to MPI. This year’s theme is on concurrency in MPI and underlying networks and we especially encourage submissions aligned with this theme.

Topics of interest (but are not limited to)

-------------------------------------------------------------------------- -------------

* Development of scalable Message Passing collective operations.

* Communication topology mapping interfaces and algorithms.

* Innovative algorithms for scheduling/routing to avoid network congestion.

* Integrated use of structured data layout descriptors.

* One-sided communication models and RDMA-based MPI.

* MPI multi-threading and threading requirements from OSes.

* Interoperability of Message Passing and PGAS models.

* Integration of task-parallel models into Message Passing models.

* Fault tolerance in MPI.

* MPI I/O.

Paper submission and publication -------------------------------------------------------------------------- ------------- There are two submission categories:

* Regular research paper: submission of full paper. Regular paper submissions are limited to 10 single-space pages (including figures, tables and references) using a 10-point on 8.5x11-inch pages (US Letter).

Templates can be found at: https://www.acm.org/publications/proceedings-template. Instructions for preparing regular papers for the proceedings will be emailed to authors of accepted papers.

* Hot topic abstract: submission of an extended abstract. These submissions target work-in-progress research on potentially controversial topics in Message-Passing. Hot topic extended abstracts are limited to 3 single-space pages: https://www.acm.org/publications/proceedings-template. Accepted hot topic extended abstracts will be published only on the ExaMPI15 website.

Regular Papers and extended abstracts should be submitted electronically at: https://tinyurl.com/ExaMPI2018

This year, ExaMPI has streamlined the paper review and submission process. Submissions will be accepted via the regular SC submission system and reviews will be available via that system. For publication of the papers, accepted papers from the SC submission system will be invited to submit the papers that were reviewed in the conference review system to a special issue of the Journal of Concurrency and Computation: Practice and Experience. This will allow for quick publication in the journal of accepted papers that only require minor revisions in the journal process, while some papers may be shepherded with major revisions overseen using the journal submission process.

Accepted papers at ExaMPI will only be published in the journal (CCPE), not the workshop proceedings, so there is no need for a 30% difference between the submitted paper and the journal submission.

Important dates -------------------------------------------------------------------------- ------------- Paper Submissions close: October 9th Paper Notification: October 23rd Papers submitted to Journal: November 9th Final notification from Journal: December 7th Final camera ready version: December 14th
