Talk title: Illuminating Data Movement: Profiling Multi-GPU Communication Paths.

GPUs have become the accelerators of choice for HPC and machine learning applications, thanks to their massive parallelism and high memory bandwidth. However, as GPU counts per node and across clusters continue to grow, inter-GPU communication has emerged as a major scalability bottleneck. Advancing GPU-centric communication requires debugging and profiling tools that can detect fine-grained, device-native data transfers, both within and across nodes. In this talk, I will present an overview of GPU-centric communication, highlighting vendor mechanisms and tool support for profiling multi-GPU communication. I will also discuss the need for more user-friendly profiling tools, to help developers understand and optimize data movement across networks.

Short Bio

Didem Unat Dr. Didem Unat received her B.Sc. degree in Computer Engineering from Boğaziçi University and her M.Sc. and Ph.D. degrees in Computer Engineering from the University of California, San Diego. Following her Ph.D., she was awarded the Luis Alvarez Postdoctoral Fellowship at Lawrence Berkeley National Laboratory. Since 2014, Dr. Unat has been leading her research group at Koç University, where she continues her scientific work on programming models, performance tools, and system software for emerging parallel architectures. She received the ACM SIGHPC Emerging Woman Leader in Technical Computing Award in 2021—becoming the first recipient of the award outside the United States. Dr. Unat has also been recognized with several other prestigious awards, including the Marie Skłodowska-Curie Individual Fellowship from the European Commission (2015), the BAGEP Award from the Turkish Academy of Sciences (2019), the Newton Advanced Fellowship from the British Royal Society (2020), and the Scientist of the Year – Young Scientist Award from Bilim Kahramanları Derneği (2021). She also brought to Türkiye the first ERC grant in Computer Science from the European Research Council. Most recently, she spent her 2024–2025 sabbatical at NVIDIA, collaborating with product teams on performance profiling tools.
