Rockstar🎓
Top SchoolJason Gunthorpe is a Distinguished Engineer and VP at NVIDIA leading Linux kernel engineering for NVIDIA Networking, with 26 years of experience designing high-performance RDMA, I/O virtualization, and embedded systems. He co-founded Obsidian Research where he invented InfiniBand routing products and led FPGA-based dataplane and network OS development, and earlier helped pioneer apt-get and archive infrastructure as a Debian developer. Jason is a hands-on kernel contributor—his public work includes substantial IOMMU subsystem enhancements to the Linux kernel tree (torvalds/linux), adding nested translation, cache coherency support, and MSI handling. Known for bridging low-level device drivers, firmware and systems architecture, he combines executive leadership with detailed implementation chops across hardware, firmware and open source communities. Based in Halifax, Nova Scotia, he brings a rare blend of entrepreneurial product delivery and deep upstream open-source influence.
