[hpc-announce] Call For Papers : EGU Session ESSI1.8 Adapting Geophysical Applications to Future HPC Architechtures

[Ravi S Nanjundiah]

Dear colleagues,

We would like to encourage you to contribute to the Session ESSI1.8 Adapting
geophysical applications to future high performance computing architectures at
the EGU general assembly 2015. (Vienna 12 April-17 April 2015).

http://meetingorganizer.copernicus.org/EGU2015/session/17170

The call for abstracts is open until the January 7th, 2015. Please note that
the deadline for support applications is on November 28th, 2014 already.

Numerical simulations have become the third pillar of science and are of great
importance for advancing our understanding of geophysical systems such as the
atmosphere, the ocean and the earth's crust. In the past years intra-node
parallelism on high performance computers has continuously been increasing,
either because of the increasing number of cores on CPUs or because of
accelerators such as GPUs or Intel Xeon Phi. This trend is particularly
reflected in the latest TOP500 ranking where many of the top-ranking
supercomputers are heterogeneous systems equipped with accelerators. In order
to fully benefit from this hardware evolution applications often require
substantial modifications.

This session will bring together experts in high performance computing and
experts in computing models of geophysical systems to discuss tools,
approaches and issues related to the adaption of earth science codes to new
and emerging supercomputers. The session particularly encourages presentations
and discussions related to the following topics:

- Analysis of application performance and identification of crucial
bottlenecks which may be relevant to the wider community.
- Experience in adapting codes to emerging high performance computing
architectures.
- Implementation approaches: re-write using new programming paradigms (CUDA,
OpenCL, CHAPEL, ...), Domain Specific Languages (DSL) or incremental
adaptation using compiler directives.
- Achieving performance portability: Is it possible to achieve good
performance with a single code across various platforms ?
- Achieving high degree of parallelism and scalability.
- Novel hardware architectures of high relevance for geophysical applications.

Best wishes,

The conveners of Session ESSI1.8
