ScalA19: 10th Workshop on Latest Advances in Scalable Algorithms for Large-Scale Systems
Novel scalable scientific algorithms are needed in order to enable key science
applications to exploit the computational power of large-scale systems. This is
especially true for the current tier of leading petascale machines and the road
to exascale computing as HPC systems continue to scale up in compute node and
processor core count. These extreme-scale systems require novel scientific
algorithms to hide network and memory latency, have very high
computation/communication overlap, have minimal communication, and have no
Scientific algorithms for multi-petaflop and exa-flop systems also need to be
fault tolerant and fault resilient, since the probability of faults increases
with scale. Resilience at the system software and at the algorithmic level is
needed as a crosscutting effort. Finally, with the advent of heterogeneous
compute nodes that employ standard processors as well as GPGPUs, scientific
algorithms need to match these architectures to extract the most performance.
This includes different system-specific levels of parallelism as well as
co-scheduling of computation. Key science applications require novel mathematical
models and system software that address the scalability and resilience challenges
of current- and future-generation extreme-scale HPC systems.
Authors are invited to submit manuscripts in English structured as
technical papers at a length of at least 6 letter size (8.5in x 11in) pages and
not exceeding 8 pages, including figures, tables, and references using the IEEE
format for conference proceedings. Reference style files are available at http://www.ieee.org/conferences_events/conferences/publishing/templates.html.
Submitted papers must represent original unpublished research that is
not currently under review for any other conference or journal. Papers not
following these guidelines will be rejected without review and further action
may be taken, including (but not limited to) notifications sent to the heads of
the institutions of the authors and sponsors of the conference. Submissions
received after the due date, exceeding length limit, or not appropriately
structured may also not be considered. Papers should be submitted electronically
All manuscripts will be peer-reviewed and judged on correctness,
originality, technical strength, and significance, quality of presentation, and
interest and relevance to the workshop attendees. Accepted papers will be
published with the IEEE Computer Society as part of the SC19 workshop
proceedings in the IEEE Xplore Digital Library. At least one author of an
accepted paper must register for and present the paper at the workshop. Authors
may contact the workshop program chair, Christian Engelmann at email@example.com, for more information.
As part of a major initiative that aims to increase the level of reproducibility
and replicability of results, ScalA19 invites authors of technical papers to
submit optional appendix information that can promote better reproducibility of
computational results. Authors are highly encouraged to provide a 2-page
Artifact Description Appendix, which will not count toward the page limit of the
- 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
- Appendices should not be used to circumvent the page limit.
