===============================================================
We are pleased to announce the fourth Workshop on Challenges and Opportunities of Efficient and Performant Storage Systems (CHEOPS'24). CHEOPS'24 will be hosted in conjunction with EuroSys'24.

The fourth 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
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
---------------------------
In order to guarantee the quality of the submissions, we have formed a globally distributed, diverse program committee. All submissions will be reviewed by the program committee. We will use HotCRP to manage the submissions (https://cheops24.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. They must be submitted electronically as PDF files formatted according to the submission rules of EuroSys (https://2024.eurosys.org/cfp.html). Accepted submissions 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.
