Webinar: Multi-GPU Programming in NCCL and NVSHMEM
About the talk:
This webinar covers high-performance communication software for GPU supercomputers. NCCL and NVSHMEM are explained, including their historical context from MPI and SHMEM. Functionality and performance are demonstrated through an example from linear algebra. Real-world results from both scientific and commercial AI use cases are also presented.
This webinar was held on 29.5.2026.
