Call for Papers

ExaMPI-19 - Workshop on Exascale MPI 2019
Sunday, November 10th, 2019
Denver, CO, USA

Held in conjunction with SC19:  The International Conference for High Performance Computing, Networking, Storage and Analysis

In Co-operation with the IEEE Computer Society Technical Consortium on High Performance Computing (TCHPC)


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 has been able to evolve, without fundamentally changing the model or 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 2018 Draft Specification. The aim of this workshop is to bring together developers and researchers to present and discuss innovative algorithms, protocols, operations, and concepts in Message Passing programming models, in particular related to MPI or MPI+X.

Topics of interest include (but are not limited to):

·       Design and development of scalable Message Passing collective operations.

·       Communication and architecture 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.

·       Support for heterogenous compute devices and heterogeneous memory systems.

·       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: . Instructions for preparing regular papers for the proceedings will be emailed to authors of accepted papers. Submitted regular papers will be peer-reviewed and accepted papers will be published by the IEEE TCHPC. Selected regular papers will be invited for submission to a special issue of a journal (more details to follow soon).


·    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. 

     Templates can be found at: . Accepted hot topic extended abstracts will be published only on the ExaMPI19 website.

Regular Papers and extended abstracts should be submitted electronically through Linklings at:
