# First International Workshop on
Challenges and Opportunities of HPC Storage Systems (CHAOSS)
The workshop 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.
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. It will take place
at the Euro-Par 2020 conference in Warsaw, Poland on either August 24
or 25, 2020. More information is available at:
https://wr.informatik.uni-hamburg.de/events/2020/chaoss
## Important Dates
Paper Submission: May 8, 2020
Notification to Authors: June 30, 2020
Registration: July 10, 2020
Camera-Ready Deadline
(Informal Proceedings): July 10, 2020
Workshop Dates: August 24 or 25, 2020
Camera-Ready Deadline: September 11, 2020
## Submission Guidelines
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will not be published in the proceedings.
Papers must be formatted according to Springer's LNCS guidelines
available at
https://www.springer.com/gp/computer-science/lncs/conference-proceedings-...
. 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.
Submissions will be submitted and managed via EasyChair at:
https://easychair.org/conferences/?conf=europar2020workshop
## 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
- 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?
