Challenges and Opportunities of HPC Storage Systems (CHAOSS)
|Euro-Par 2020 has been converted to an all-virtual event. Our workshop will follow this format and thus take place virtually. Please note that the submission deadline has been updated accordingly.|
The first workshop on “Challenges and Opportunities of HPC Storage Systems” (CHAOSS) is aimed at researchers, developers of scientific applications, engineers and everyone interested in the evolution of HPC storage systems. As the developments of computing power, storage and network technologies continue to diverge, the performance gap between them widens. This trend, combined with the growing data volumes, results in I/O and storage bottlenecks that become increasingly serious especially for large-scale HPC storage systems. The hierarchy of different storage technologies to ease this situation leads to a complex environment which will become even more challenging for future exascale systems.
The main objective of this workshop is to explore the intersection of self-describing data formats and other data organizations with multi-tier memory and storage hierarchies. The goal is to find the right balance for different workloads. This workshop is a venue for papers exploring topics related to data organization and management along with the impacts of multi-tier memory and storage for optimizing application throughput. We encourage submissions of early stages of research.
Some dates have been updated due to the move to a virtual event.
|Notification to Authors|
|Camera-Ready Deadline (for Informal Proceedings)||July 28, 2020|
|Workshop Dates||August 24, 2020|
|Camera-Ready Deadline||September 11, 2020|
Submissions will be submitted and managed via EasyChair. Only original and novel work not currently under review in other venues will be considered for publication. The papers should not exceed 12 pages (including title, text, figures, appendices and references). Papers of less than 10 pages will be considered as short papers that can be presented at the conference but will not be published in the proceedings. They must be submitted electronically as PDF files formatted according to Springer's LNCS guidelines. All submissions will be reviewed by at least 3 reviewers from the technical program committee. Accepted papers will be published in a separate LNCS workshop volume after the conference.
One author of each accepted paper is required to register for the workshop and present the paper. Due to the virtual format, presentations have to be given either via pre-recorded video or live stream. In both cases, the organizers will collect questions during the workshop and perform a live Q&A session with the presenter.
If there are any questions regarding submission or other aspects of the workshop, please feel free to contact the organizers.
Topics of Interest
Submissions may be more hands-on than research papers and we therefore explicitly encourage submissions in the early stages of research. Topics of interest include, but are not limited to:
- Kernel and user space file/storage systems
- Parallel and distributed file/storage systems
- Data management approaches for heterogeneous storage systems (such as SCM and NVRAM combined with HDDs)
- Management of self-describing data formats
- Metadata management
- Approaches using query and database interfaces
- Hybrid solutions using file systems and databases
- Optimized indexing techniques
- Data organizations to support online workflows
- Domain-specific data management solutions
- Related experiences from users: what worked, what didn't?
