===============================================================

The sixth Workshop on Challenges and Opportunities of Efficient and
Performant Storage Systems (CHEOPS)

April 27st, 2026 

Edinburgh, Scotland, UK 

Held in conjunction with EuroSys 2026

===============================================================

We are pleased to announce the fourth Workshop on Challenges and
Opportunities of Efficient and Performant Storage Systems (CHEOPS'26).
CHEOPS'26 will be hosted in conjunction with EuroSys'26. 

The sixth 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 and large language
models, 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, and reducing latency in the software stack to leverage new
memory hierarchies enabled by technologies like CXL. 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, so we 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

Virtual file systems

Cloud, parallel and distributed file/storage systems

Network challenges, such as scalability, QoS and partition-ability

Approaches for low-latency and heterogeneous storage systems

Computational storage devices and compute in memory technologies

Metadata management

Machine Learning and Artificial Intelligence

Storage requirements of ML and AI applications (including LLMs, vector
embeddings, KV cache data, model training checkpoints )

Using ML and AI within storage systems (e.g., to replace heuristics, to
optimize storage and I/O systems)

Content-aware storage systems

Hybrid solutions using file systems and databases

Approaches using query and database interfaces, including key-value stores

Optimized indexing techniques

Data organizations and movement to support online workflows

Data privacy and data security

Domain-specific data management solutions

Application I/O profiling and characterization

Tools for storage system performance profiling, modeling, and analysis 

Data reduction techniques

Lossless and lossy compression, deduplication, dimensionality reduction,
surrogate modeling

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://cheops26.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, and appendices but excludes the references. They must be submitted
electronically as PDF files formatted according to the submission rules of
EuroSys (https://2026.eurosys.org/index.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.
