Dear colleagues,

The HPC symposium “Computational Science at Scale” CoSaS 2018 will take place in Erlangen, Germany from Wednesday, September 5 until Friday, September 7, 2018. This symposium is organized within the scope of the DFG priority programme "Software for ExaScale Computing" (SPPEXA) that addresses fundamental research on the various aspects of HPC software.

The main objectives of the symposium are to review the state of art in large-scale numerical simulation with applications in science and engineering and to be a forum for the exchange of results and ideas in HPC.

Specific topics of interest include, but are not limited to: Large-scale parallel applications Scalable parallel algorithms Parallel computer architectures Performance analysis, tuning, and debugging Fault tolerance

The program will consist of high-level invited talks, a public evening lecture, and a poster session. This session will include a Poster Blitz (i.e. a brief presentation to promote your poster) and a Best Poster Award. Abstracts (of up to 150 words) for the posters from the HPC community are welcome and should be submitted before Wednesday, July 18, 2018 via https://www.cosas2018.fau.de .

Important dates: July 18, 2018 poster abstract submission ( extended ! ) July 23, 2018 acceptance notification August 6, 2018 registration deadline
