Call for Papers

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, datacenters and Clouds. This yearly conference is attended by leaders in industry and academia. The atmosphere provides for a wealth of opportunities to interact with individuals at the forefront of this field.

Themes include cross-cutting issues spanning computer systems, networking technologies, and communication protocols for high-performance interconnection networks. This conference is directed particularly at new and exciting technology and product innovations in these areas. Contributions should focus on real experimental systems, prototypes, or leading-edge products and their performance evaluation. In addition to those subscribing to the main theme of the conference, contributions are also solicited in the topics listed below. This year's best papers on interconnect microarchitecture will be invited to submit extended versions of their papers to a special edition of IEEE Micro.

Building on last year's successful technical program, keynotes, sessions, and panels on datacenter networking and their requirements, and solutions, in 2015 Hot Interconnects moves to the Oracle Santa Clara Campus, Santa Clara, CA for the conference. This year's conference focuses on data-center, virtualized, and cloud networking. We hope you can join us there.

Paper format

We invite papers to be submitted either as regular, long papers (6-8 pages) or as short papers (3-4 pages). Short papers could be positional papers, industry papers, or papers describing hot-off-the-press breaking research results, and will judged accordingly and independently from the regular papers.

Publication & Presentation

Papers accepted s will be included in proceedings by the IEEE and appear on IEEE Xplore. Papers accepted will be presented at the HotI symposium.


An award will be given to the Best Student Paper ($1,000). To be eligible for the Best Student Paper award the first (and main) author(s) must be a full-time student(s) at the time of submission. This year HotI will provide Student Travel Awards to eligible applicant students. Information on application for the travel awards can be found here
