Workshop Overview
Abstract
The future of computing systems is inevitably embracing a disaggregated and
composable pattern: from clusters of computers to pools of resources that can be dynamically combined
together and tailored around application requirements.
With new interconnects for interfacing CPU, memory and peripherals becoming a commodity (e.g., CXL),
disaggregation and composability in computer systems is expected to become a predominant design pattern.
This paradigm change increases the level of heterogeneity from what is possible with statically defined
servers to software-defined dynamically composed servers, resulting in an increased memory and
accelerators capacity/availability and improved resource utilization in a cost-effective way, reducing the
overall total cost of ownership.
This new class of systems, that we term Heterogeneous and Composable Disaggregated Systems (HCDS),
provide a system design approach for reducing the imbalance between workloads resource requirements and
the static availability of resources in a computing system, while making room for novel distributed system
approaches in processes communication and data exchange.
The HCDS workshop aims at exploring the novel research ideas around composable disaggregated systems and
their integration with operating systems and software runtimes to maximize the benefit perceived from user
workloads.

Call for Papers
The HCDS workshop aims at exploring the novel research ideas around composable disaggregated systems and their integration with operating systems and software runtimes to maximize the benefit perceived from user workloads.
Papers are solicited from the areas, including, but not limited to:
Hardware and Prototyping
- Novel composable systems architectures (e.g., CXL based)
- Composable system prototypes and proof-of-concept
- Interconnect technologies (such as CXL)
- Memory pooling, and memory disaggregation
Modeling and Evaluation
- Heterogeneous Composable Systems simulation
- Characterization of heterogeneous composable systems from the perspective of performance, energy consumption and reliability
- New algorithms and performance models to manage and use HCDS
- Memory pooling, and memory disaggregation
System software and programming models/tools
- Operating system designs to support HCDS, such as memory profiling methods, memory management (e,g, page migration and allocation)
- Control plane software and runtime systems for management of composable systems
- Programming models for heterogeneous composable memory
- Analysis / profiling tools and techniques for composable systems
- Virtualization for composable heterogeneous systems
Applications and Use cases
- Use cases for heterogeneous composable systems, such as (but not limited to) deep-learning and large language model (llm) inference/serving/training/fine-tuning, agentic AI systems, data-intensive analytics, data input pipelines/streaming and scientific and HPC applications
- AI system decomposition (e.g., distributed inference in Dynamo) for system disaggregation
- CXL memory sharing and pooling for AI
- Co-design of AI model and system disaggregation
Submission Instructions
Each manuscript will be evaluated with a double-blind review
process. Authors must omit at submission time their names or any information that can disclose
their identity. Manuscripts length must be 4-6 pages including figures and
tables but excluding references. All manuscripts must use the sigplan ACM conference style. It is also
expected that all accepted papers will be presented at the workshop by one of the authors.
Papers accepted to the workshop will have the chance to be published on the ACM Digital Library
following the new ACM open access publishing model.
We offer the possibility to opt-out from
publishing submitted work to the ACM proceedings. This applies for instance to authors wishing to
re-submit an extended version to another venue that does not allow the work to have appeared in
official proceedings or, the authors are not part of the ACM open network and do not have the funds for
supporting the proceedings processing costs.
In such case, if your manuscript is accepted, it will only be published on the workshop website.
If you are wishing to do so, send the organizers an email right after
submitting your manuscript.
Important note to authors about the new ACM open access publishing model
ACM has introduced a new open access publishing model for the International Conference Proceedings
Series (ICPS).
Authors based at institutions that are not yet part of the ACM Open program and do not qualify for
a
waiver will be required to pay an article processing charge (APC) to publish their ICPS article in
the ACM Digital Library. To determine whether or not an APC will be applicable to your article,
please follow the detailed guidance here.
Further information may be found on the ACM website, as follows:
- details of the new ICPS publishing model
- details of the ACM Open program
