Topics
Areas or research interest include, but are not limited to:
- Modeling node topology
- Modeling network and communication
- Performance analysis of application to understand affinity
- Affinity metrics
- Runtime support for extracting affinity from application
- Code analysis in order to understand communication pattern
- Algorithm to improve locality
- Language, abstraction and compiler support for data locality
- Data structure and library support to better manage memory access
- Runtime-system and dynamic locality management
- System-scale locality optimization
- Validating locality optimization at thread or process level
- Memory management
- Locality management in large-scale application
- Impact of Locality to application
The COLOC workshop seeks contribution targeting (i) methods and tools to understand hierarchical topology that describes the characteristics of platform resources (ii) abstractions and tools to better manage data placement, thereby maximize application performance, and (iii) validating data-locality optimization, using applications from different domains. The aim of this workshop is to bring together researchers who are either developing tools, or using them to enhance performance through the use of locality and topology. Of particular interest are case studies that highlight the impact of using these tools and abstraction. While high-performance computing is our primary focus, contributions on data locality and energy efficiency, data locality in the context of BigData or deep learning applications are also of great interest.
Targeted audience
- HPC application developers interested in exploring new ways to optimize their code.
- HPC centers and clusters managers to enhance cluster usage and application efficiency.
- Academics and researchers in scientific computing.
What and how to submit a paper
Paper, in PDF format, should be submitted to the workshop easychair submission site (choose login as author then new submission and WS01: Workshop on data locality (COLOC)). Papers should be formatted according to the LNCS style that can be downloaded from the springer website. Page limit is 12. It includes everything (text, figures, references) and will be strictly enforced by the submission system. Complete LaTeX sources must be provided for accepted papers. Papers should be typeset using the single column format. All submitted research papers will be peer-reviewed. Only contributions that are not submitted elsewhere or currently under review will be considered. Authors of accepted papers will have to sign a Springer copyright form. Short papers (2-4 pages) are also accepted submission. However, only paper which camera-ready version longer than 10 pages will be included in the proceedings published by Springer in the ARCoSS/LNCS series. Accepted paper will be presented during the workshop session of the Euro-Par 2021 conference in Lisbon Portugal.
