CFP: First Int'l Workshop on Communication Optimizations in HPC (COMHPC) @SC16, Deadline: August 19‏‏

First International Workshop on Communication Optimizations in High Performance Computing 

In cooperation with ACM SIGHPC


Friday, November 18, 2016

co-located with

SC16: The International Conference for High Performance Computing, Networking, Storage and 

November 13-18, 2016


Call for Papers: 

As HPC applications scale to large supercomputing systems, their communication and 
synchronization need to be optimized in order to deliver high performance. In order 
to achieve this, capabilities of modern network interconnect and parallel runtime 
systems need to be advanced and the existing ones to be leveraged optimally. The 
workshop will bring together researchers and developers to present and discuss work 
on optimizing communication and synchronization in HPC applications. This includes 
state-of-the-art methodological and algorithmic advances in topology-aware or 
topology-oblivious blocking and non-blocking collective algorithms, offloading of 
communication to network interface cards, topology aware process mappings for 
minimizing communication overhead on different network topologies such as dragonfly, 
high-dimensional torus networks, fat trees, optimizations for persistent communication 
patterns, studies and solutions for inter-job network interference, overlapping of 
communication with computation, optimizing communication overhead in the presence of 
process imbalance, GPU-GPU and GPU-CPU communication. The workshop also aims at 
bringing researchers together to foster discussion, collaboration and ideas for 
optimizing communication and synchronization that drive design of future peta/exa-scale 
systems and of HPC applications. In addition, we expect that researchers and others 
looking for research directions in this area will get up-to-date with the state of the 
art so that they can drive their research in a manner that will impact the future of 
communication methods in high performance computing.

Blocking and non-blocking collective operations

Paper Submission Guidelines:

Papers must follow the ACM format (see 
Submissions are limited to up to 10 pages. We also encourage submission of work-in-progress and 
late-breaking ideas that illustrate promising results. The 10-page limit includes figures, tables, 
and appendices, but does not include references, for which there is no page limit. Papers should be 
submitted electronically via EasyChair: 
Submitted papers should not have appeared in or be under consideration for a different workshop, 
conference or journal. Papers will be peer-reviewed by the Program Committee for novelty, 
scientific merit, technical strength, originality, quality of presentation and scope of the 
workshop. It is also expected that at least one author of an accepted paper must register for and 
attend the workshop. Accepted papers will be published in the workshop proceedings by SIGHPC and 
made available in the ACM Digital Library and IEEE Xplore.
