Welcome to the 29th iteration of the IEEE Hot Interconnects symposium. HotI29 will be held 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, and data centers. Leaders in industry and academia attend the conference to interact with individuals at the forefront of this field.

Our objective is to address the data center networking and the supercomputing communities. We hope you can join us and benefit not only from the content but also from the prime networking opportunities this event always offers.

August, 17 - 19th, Online Conference

Disaggregation Leading to Reaggregation

A special theme of Hot Interconnects this year is disaggregation leading to reaggregation, i.e., technology transitions that offer the potential to rethink system architecture towards greater optimization. Processors, storage, memory, interconnects, and now accelerators have traditionally been considered as monolithic systems, but recent technology transitions have made it possible to break them down into modular components, fostering novel ways of designing new architectures via recombining the modules for new benefits. Moreover, energy consumption in data centers is on an unsustainable rise and recent projections even indicate that interconnection energy usage will exceed computing within the next five years. So the criteria for optimizing system design now include performance, cost, size, reliability, and energy efficiency.

Hot Interconnects 2022 will present a riveting program exploring these issues and tradeoffs and we invite authors to submit high quality papers across a broad range of topics from networking technologies and communication protocols for high-performance (or low energy) interconnection components and networks to novel system architectures, especially regarding disaggregation and reaggregation.
