About me

I am a MS CS student at the University of Illinois Urbana-Champaign, broadly interested in the area of Operating Systems: Task scheduling, energy, memory management at scale.

Prior to joining UIUC, I worked as a Kernel Developer in IBM, Linux Technology Center since 2019 where I was part of the CPU team responsible for building and deploying upstream solutions for Scheduling and Energy management problems that were faced by both the IBM POWER platform and the community. Before joining at IBM, I have graduated with Bachelor's in Technology from PES University.

Junk Code

Cloud and Containerization

  1. CPU namespace

    CPU isolation for containers. Provides consistency of sys/proc/cgroup fs interfaces. Also, improves security and performance. Linux Patches , Phoronix article , Linux Conf. Australia 2022

  2. Cgroup Control

    A simple script that helps in creating and controlling cgroups. Used when we want to avoid Docker overheads, and either do not wish to directly interact with the cgroup-tools like cgcreate,cgexec, etc; or this toolset is unavailable/unsupported. Github Gist

Energy Management

  1. Weighted TEO Governor

    Improvements to the current idle state governor's non deterministic event prediction algorithm. Uses a weighted history to create a probability distribution of the idle states rather the sliding window history. Linux Patches , LWN article

  2. CPU-idle latency self-test framework

    Estimate the wakeup latency caused by going into idle states. Hardware may certify certain latencies, however firmware and kernel overheads may exist. This will then lead idle governors making energy mangement decisions based on incorrect residency assumptions. Aim is to find significant deviations between advertised latency and residency values in the kernel space. Linux Patches


  1. CPU-idle Verifier

    A processor may lose information in many registers based on how deep of an idle state it has gone. The platform saves and restores these registers on a wakeup. However, any inconsistency in restoring can lead to catastrophic failure which may not always crash the system upfront. A kernel debugging patch written for IBM POWER9 to verify the consistency of the registers before and after an idle state is evoked. Linux Patches

  2. CPU hotplug and Idle stress test

    Emulates long running behavior of usage of CPU power management in relatively short and intensive runs. Bash Script

  3. TimeBase Drift

    If the hardware timebase does not perform with monotonicity, the system fails in a cascading dominos of subsystem failures, making it incredibly difficult to pinpoint the root cause. A debug kernel module to identify timebase anomalies on the platform had been written to test any and all processors for such anomalies. Kernel module
