The 33rd IEEE Symposium on High-Performance Interconnects, Hot Interconnects (HotI 2026), will take place virtually
IEEE Hot Interconnects is the premier international forum for researchers and developers of state-of-the-art hardware and software architectures and implementations for interconnection networks of all scales, ranging from multi-core, on-chip interconnects to those within systems, clusters, data centers, and clouds. This yearly conference is attended by leaders in industry and academia.

- Novel and innovative interconnect architectures
- Accelerator interconnects, e.g. NVLINK, Infinity Fabric
- Network software/hardware designed for AI/ML workloads
- Multi-core processor interconnects
- System-on-Chip Interconnects
- Chiplet-interconnect technologies such as UCIe and BOW
- Advanced chip-to-chip communication technologies
- Optical interconnects
- Protocol and interfaces for inter-processor communication
- Survivability and fault-tolerance of interconnects
- High-speed packet processing engines and network processors
- System and storage area network architectures and protocols
- High-performance host-network interface architectures
- High-bandwidth and low-latency I/O
- Pb/s switching and routing technologies
- Innovative architectures for supporting collective communication
- Novel communication architectures to support cloud & grid computing
- Centralized and distributed cloud interconnects
- Requirements driving high-performance interconnects
- Traffic characterization for HPC systems and commercial data centers
- Software-defined networking and software overlay networks
- Software for network bring-up, configuration and performance management (OpenFlow, OpenSM)
- Data Center Networking
TBD
Paper Format
This year we invite papers to be submitted either as regular (long) papers (up to 10 pages) or as hot topic papers (up to 4 pages). Hot topic papers could be positional papers, industry papers, or papers describing hot-off-the-press breaking research results and will be judged accordingly and independently from the regular papers.
- Papers need sufficient technical detail to judge quality and suitability for presentation. Submissions must conform to [IEEE ethics standards]
- Submissions should include title, author, abstract, and paper in double-column, see [IEEE format] for details.
- Papers will be submitted electronically through EasyChair (link TBD) and will undergo a single-blind review process.
- Regular papers: up to 10 pages (including technical content and figures), excluding references and any appendices. Appendices (if any) are limited to 5 pages (the limit might be extended upon committee approval in advance). Reproducibility appendices are encouraged but no official verification is provided by the HotI program committee.
- Hot topic papers: up to 4 pages (including technical content and figures) excluding references. Appendices are not allowed for hot topic papers. Hot topic papers should describe initial research or early first-of-a-kind results (from industry or academia) and will be reviewed independently from the regular papers. Hot topic papers will not be considered for IEEE Micro special issue.
- Materials other than the abstract, main paper body, and references will be read at the committee’s discretion.
- Accepted papers will be submitted for inclusion into IEEE Xplore subject to meeting IEEE Xplore’s scope and quality requirements. We plan to invite regular papers with the highest review scores for an [IEEE Micro] Special issue submission.
- After a paper is accepted, the authors must follow the conference and [IEEE CPS guidelines] in publishing the paper.
Best Papers
High impact papers will be considered for “Best Industry Paper” (primary author(s) from industry) and “Best Academic Paper” (primary author(s) from academia or non-profit research laboratories) categories.
2025 Hot Interconnects best papers:
[Best Industry Paper] Accelerating Frontier MoE Training with 3D Integrated Optics (Taylor Groves, Mikhail Bernadskiy, Ho John Lee, Peter Carson, Thomas Graham and Eric Yeh (Lightmatter)) <hyperlink to IEEE Xplore>
[Best Academic Paper] Deadlock-free routing for Full-mesh networks without using Virtual Channels (Alejandro Cano Cos, Cristóbal Camarero, Carmen Martinez (Universidad de Cantabria) and Ramon Beivide (Universidad de Cantabria, Barcelona Supercomputing Center)) <hyperlink to IEEE Xplore>
Safety and Well-being
Given the success of previous year’s online format, Hot Interconnects 2025 will continue to be an online conference.
