About

Krishnakant Jaju is a highly skilled Senior System Software Engineer at NVIDIA with over 10 years of experience in the system software domain. He is an expert in Virtualization, Linux, Device Drivers, Data Structures, and Algorithms. Currently, Krishnakant is working on NVIDIA vGPU (Virtual GPU) – SRIOV vGPU where he enabled the first SR IOV capable NVIDIA chip based on Ampere architecture. He also implemented a dirty page tracking solution for guest system memory used by SR IOV capable vGPUs. Krishnakant has also worked on adding MIG (Multi-Instance GPU) support on NVIDIA A100 board running vGPU software and integrated MIG management with Hypervisor and vGPU Manager. Krishnakant has also worked on NVIDIA vGPU (Virtual GPU) – Live Migration, where he was involved in designing and implementing the vGPU Live Migration architecture. He supported vGPU live migration by adding new communication and notification interfaces between VMM and vGPU. Krishnakant also worked on save and restore of the vGPU device state (SW and HW) and compatibility algorithms between source and destination. He implemented selective GPU Frame Buffer copy algorithm to reduce Frame buffer memory transfer during Live Migration. Krishnakant has also contributed to NVIDIA vGPU (Virtual GPU) – vGPU Management, where he implemented the backend of NVIDIA GRID vGPU Management. He developed a system service that reads predefined vGPU types, with fixed configurations of framebuffer, display heads, and other capabilities, from an XML file and writes them to NVIDIA kernel driver. Krishnakant also extended NVIDIA management tools to support vGPU and developed a C-based SDK for monitoring and managing various states of NVIDIA GRID vGPUs. Krishnakant holds a Bachelor of Technology (B.Tech.) in Computer Engineering from the College of Engineering, Pune. He also has a degree in Vocational Subject: Computer Science from Brijlal Biyani Science College (HSC) and a Bachelor of Technology from Dnyanmata High School. Krishnakant's tech stack includes Software Engineering, Backend, Python, and Infra.
