Welcome to the 31st iteration of the IEEE Hot Interconnects symposium. HotI’2024 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.

2024 Conference Theme – Can Interconnects Keep up with AI?

The explosion of AI and workloads related to machine learning and deep learning boggles the mind. Whether in massive data centers, edge locations, automobiles, or consumer appliances, AI stands to improve many tasks useful to people at work or at leisure. The demand for GPUs, DPUs, TPUs, and IPUs taxes the ability of their manufacturers to meet the market demand. Efficient utilization of these xPUs requires high speed and highly scalable interconnects. Whether between xPUs or between an xPU and memory, data transfer can easily become a bottleneck in computing efficiency. In this edition of IEEE Hot Interconnects, we explore advances in interconnection networks that alleviate this bottleneck. Solutions including optical circuit switching, dense photonic data paths, high-performance fabrics, and more will expand from the specialized applications of HPC to the pervasive applications of AI and in the process will become more affordable. This year’s HotI will thus be captivatingly relevant.

Thank you to our 2023 sponsors!

IEEE Computer Society Open Conference Statement

Equity, Diversity, and Inclusion are central to the goals of the IEEE Computer Society and all of its conferences. Equity at its heart is about removing barriers, biases, and obstacles that impede equal access and opportunity to succeed. Diversity is fundamentally about valuing human differences and recognizing diverse talents. Inclusion is the active engagement of Diversity and Equity. A goal of the IEEE Computer Society is to foster an environment in which all individuals are entitled to participate in any IEEE Computer Society activity free of discrimination.

For this reason, the IEEE Computer Society is firmly committed to team compositions in all sponsored activities, including but not limited to, technical committees, steering committees, conference organizations, standards committees, and ad hoc committees that display Equity, Diversity, and Inclusion.

IEEE Computer Society meetings, conferences and workshops must provide a welcoming, open and safe environment, that embraces the value of every person, regardless of race, color, sex, sexual orientation, gender identity or expression, age, marital status, religion, national origin, ancestry, or disability. All individuals are entitled to participate in any IEEE Computer Society activity free of discrimination, including harassment based on any of the above factors.

IEEE Event Conduct and Safety Statement

IEEE believes that science, technology, and engineering are fundamental human activities, for which openness, international collaboration, and the free flow of talent and ideas are essential. Its meetings, conferences, and other events seek to enable engaging, thought provoking conversations that support IEEE’s core mission of advancing technology for humanity. Accordingly, IEEE is committed to providing a safe, productive, and welcoming environment to all participants, including staff and vendors, at IEEE-related events.

IEEE has no tolerance for discrimination, harassment, or bullying in any form at IEEE- related events. All participants have the right to pursue shared interests without harassment or discrimination in an environment that supports diversity and inclusion. Participants are expected to adhere to these principles and respect the rights of others. IEEE seeks to provide a secure environment at its events. Participants should report
any behavior inconsistent with the principles outlined here, to on site staff, security or venue personnel, or to eventconduct@ieee.org
