Full Job Description
NVIDIA is leading the way in groundbreaking developments in Artificial Intelligence, High Performance Computing and Visualization. The GPU, our invention, serves as the visual cortex of modern computers and is at the heart of our products and services. Our work opens up new universes to explore, enables amazing creativity and discovery, and powers what were once science fiction inventions from artificial intelligence to autonomous cars. Come work for the team that brought to you NCCL, NVSHMEM & GPUDirect. Our GPU communication libraries are crucial for scaling Deep Learning and HPC applications! We are looking for a motivated Performance engineer to influence the roadmap of our communication libraries. The DL and HPC applications of today have a huge compute demand and run on scales which go up to tens of thousands of GPUs. The GPUs are connected with high-speed interconnects (eg. NVLink, PCIe) within a node and with high-speed networking (eg. Infiniband, Ethernet) across the nodes. Communication performance between the GPUs has a direct impact on the end-to-end application performance; and the stakes are even higher at huge scales! This is an outstanding opportunity for someone with HPC and performance background to advance the state of the art in this space. Are you ready for to contribute to the development of innovative technologies and help realize NVIDIA's vision? ## **What you will be doing:** * Conduct in-depth performance characterization and analysis on large multi-GPU and multi-node clusters. * Study the interaction of our libraries with all HW (GPU, CPU, Networking) and SW components in the stack * Evaluate proof-of-concepts, conduct trade-off analysis when multiple solutions are available * Triage and root-cause performance issues reported by our customers * Collect a lot of performance data; build tools and infrastructure to visualize and analyze the information * Collaborate with a very dynamic team across multiple time zones ## **What we need to see:
