About

I am a Linux Kernel Developer and Systems Engineer. Previously, I was a part of the Server OS Team at AMD leading the Scheduler and the Power Management workgroup. I also co-maintained the amd-pstate frequency scaling driver in the Linux Kernel. Prior to that,, I worked at the Linux Technology Center at IBM, on the Linux Scheduler and Energy Management for IBM POWER servers. I was also a part of a small group at IBM that is working on adding Full-System simulation support for POWER architecture on the gem5 simulator. Prior to taking a break to pursue my higher studies, I had worked as a Linux kernel programmer from June'06 to July'10 at the Linux Technology Centre in IBM India. During this time, I have worked on subsystems within the Linux Kernel including CPUFreq, CPU-Hotplug, Preemptible RCU, and more recently Power Aware Scheduling and Load Balancing. For a while I had also dabbled with the QEMU internals while attempting to build a file-system passthrough from the guest onto the host. Specialties: Programming Skills: C, C++, Java, Python, Haskell, pyGTK, Shell Programming. Open Source Projects: Linux Kernel, QEMU, gem5, OPAL Platforms: Linux.
