Some of My Latest Projects

  • numa

    SNAKE: Spiced-up Numa-Aware KErnel

    Added support for weighted interleaved memory allocation policy on NUMA machines to the Linux Kernel, accessible via a new system call, named "set_mempolicy_w".
    Currently available on Kernel v4.17.2, a small patch for other versions is available though :)
    [github repo]

    numactl+

    Added --weights option (and required underlying inner workings) to the original numactl, enabling programs to make use of the weighted interleaved memory allocation policy feature mentioned above.
    [github repo]

  • maple

    MAPLE: Memory Access ProfiLEr

    MAPLE is a Pin-based tool to provide profiling memory accesses of applications at page-level.

  • firehose

    Firehose: Scaling Publish-Subscribe

    [more info]

  • firefly messaging

    Firefly: Light-weight Headache-free Event Loop

    Firefly is built on the top of epoll as an abstract async event loop. It is aimed to be as light and fast as possible.

  • mimircache reza karimi

    MimirCache

    A platform for analyzing cache traces. It allows you to visualize your cache traces from different perspectives, and it incorporates time factor when comparing cache replacement algorithms. MimirCache is a masterpiece mostly made by Jason Yang at Ymir's lab. I have contributed in code reviews and implementation of some cache replacement algorithms. Hopefully, I'll find more time for more contributions. [Project's Website]

  • emoji emotions

    Emotion-aware Ranking

    Incorporating sentiment and emotions to find most-relevant tweets. [Slides]

  • carvana kaggle

    Don't Get Kicked!

    Predict if a car purchased at auction is a lemon.
