Conference theme
The prevalence of multicore and manycore technologies has brought ubiquitous parallelism and a huge theoretical potential for compute-intensive tasks. In theory, advancements in technology bring us closer to the solution of the Grand Challenges in modern computing. In practice however, it is hard to achieve maximal throughput in the results and to exploit all available capabilities. Due to the inevitable paradigm shift towards multicore technologies, parallelism is now affecting all kinds of software development processes – from large-scale numerical simulation to desktop commodity applications.

The trend for increased compute capability and more diverse hardware with its evermore complex topologies continues: In recent systems parallelism spreads over several levels of the system and heterogeneity is growing on the node as well as on the chip level. Data is kept across a nested hierarchy of memory stages and data locality becomes even more important. Most applications and algorithms are not yet ready to utilize available capabilities and a tremendous effort is required to close the gap. Different technologies and processing models, non-adjusted interfaces, and incomplete tool chains complicate holistic programming approaches and impede programmer’s productivity. On the other hand, resource contention, data conflicts and hardware bottlenecks keep performance away from theoretical peak. At the current state of the art in technologies and methodologies an interdisciplinary approach is required to tackle the obstacles in manycore computing.
Only a comprehensive approach with contributions from computer science, applied mathematics, high performance computing, and engineering disciplines can face the multicore challenge. Compute- and memory-intensive applications can only benefit from the full hardware potential if all features on all system levels are taken into account in a holistic approach.

This conference is the 3rd in a series, starting in 2010 in Heidelberg at the Heidelberg Academy of Sciences (HAW) and 2011 at the Karlsruhe Institute of Technology (KIT) and the Engineering Mathematics and Computing Lab (EMCL). It aims to combine new aspects of multi-/manycore microprocessor technologies, parallel applications, numerical simulation, software development and tools. Contributions are welcome from all participating disciplines. Particular emphasis is placed on the support and advancement of young scientists.
