Postdoctoral Appointee — HPC & AI Interconnect

The Argonne Leadership Computing Facility (ALCF) is dedicated to advancing scientific discoveries and engineering breakthroughs by providing world-class computing facilities in collaboration with the computational science community. We empower researchers to tackle some of the most complex global challenges through our unique blend of supercomputing resources and computational science expertise.

The ALCF is seeking a postdoctoral appointee to join our team focused on designing the communication infrastructure for next-generation High-Performance Computing (HPC) and Artificial Intelligence (AI) systems. This position offers an exciting opportunity to work at the intersection of HPC and AI, addressing critical communication bottlenecks and optimizing network interconnects for large-scale distributed systems.

Objective:

• Develop and optimize workload-specialized interconnects and network-aware communication strategies to enhance the performance of AI and HPC workloads.
• Implement adaptive routing techniques and Software-Defined Networking (SDN) solutions to dynamically manage network congestion and improve communication efficiency.
• Research and develop topology-aware collective communication algorithms to optimize data-intensive operations in scientific and AI applications.
• Investigate machine learning techniques to inform heuristic methods for routing optimization, bridging theoretical insights with practical implementations.
• Address inter-job interference through traffic pattern awareness, creating isolated virtual network domains to maximize resource utilization and minimize performance variability.

Benefit to ALCF:

This postdoctoral position will contribute to the development of scalable and intelligent communication systems for large-scale computing platforms. By optimizing network interconnects and communication strategies, the appointee will help ALCF enhance the performance of AI-driven applications and HPC workloads, ensuring efficient utilization of resources and improved system predictability.
