===============================================================
We are pleased to announce the third Workshop on Challenges and Opportunities of Efficient and Performant Storage Systems (CHEOPS'23). CHEOPS'23 will be hosted in conjunction with EuroSys'23.

The third workshop on "Challenges and Opportunities of Efficient and Performant Storage Systems" (CHEOPS) is aimed at researchers, developers of scientific applications, engineers and everyone interested in the evolution of storage systems. As the developments of computing power, storage and network technologies continue to diverge, the bandwidth performance gap between them widens. This trend, combined with the ever growing data volumes and data-driven computing such as machine learning, results in I/O and storage limitations, impacting the scalability and efficiency of current and future computing systems. Some of these challenges are quantitative, such as scale to match exascale system requirements, or latency reduction of the software stack to efficiently integrate new generations of hardware like storage class memory (SCM). Some other issues are more subtle and arise with the increased complexity of the storage solutions, like new smarter and more potent data management tools, monitoring systems or interoperability between I/O components or data formats.

The main objective of this workshop is to discuss state-of-the-art research, innovative ideas and experiences that focus on the design and implementation of storage systems in both academic and industrial worlds.

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:

- Operating system optimizations
- Kernel and user space file/storage systems
• Including virtual file systems
- Cloud, parallel and distributed file/storage systems
• Network challenges, such as scalability, QoS and partitionability
- Approaches for low-latency and heterogeneous storage systems
• Such as SCM and NVRAM combined with HDDs
- Metadata management
- Provenance capture and management
- Machine Learning and Artificial Intelligence
• Storage requirements of ML and AI applications
• Using ML and AI within storage systems (e.g., to replace heuristics)
- Hybrid solutions using file systems and databases
• Approaches using query and database interfaces, including key-value stores
• Optimized indexing techniques
- Data organizations to support online workflows
- Data privacy and data security
- Domain-specific data management solutions
• Application I/O characterization
- Storage systems modeling and analysis tools
- Data reduction techniques
• Lossless and lossy compression, deduplication
- UI/UX for storage systems
- Related experiences from users: what worked, what didn’t?
• Feedback and empirical evaluation of storage systems

Paper Submissions
---------------------------
All papers need to be submitted electronically through HotCRP with PDF format through the following link: https://cheops23.hotcrp.com/. The reviewing process will be double blind with at least 3 reviews for each submission. An online discussion will determine which papers to accept.

Only original and novel work not currently under review in other venues will be considered for publication. Submissions can either be full papers (6 pages) or short papers (4 pages). The page count includes the title, text, figures, appendices but excludes the references. The papers must be formatted according to the submission rules of EuroSys.

Accepted papers will have to comply with the EuroSys proceedings format. One author of each accepted paper is required to register for the workshop and present the paper. Extended versions of selected papers will be considered for publication in the ACM SIGOPS Operating Systems Review journal.
