Smaller argparsh binaries
Making argparsh smaller and 3x faster by optimizing binary size!
Welcome to my website! I’m a second year PhD Student at UT Austin, advised by Chris Rossbach. My topics of interest are Operating System Design, Systems for ML, and compilers.

Optimizing argparsh
argparsh allow shell scripts to have better argument parsing. However, it requires many repeated invocations of the argparsh process - how can we reduce the overhead of spawning argparsh processes? In this post we make argparsh 3.46x faster by using static linking and nostd.
Injecting Kernel Controlled Threads to Userspace Processes
Linux lacks a mechanism for injecting a kernel-controlled thread into a userspace process. Recently, I implemented a hacky solution (involving process brain surgery) and wanted to write about it. Implementation code can be found at https://github.com/aneeshdurg/atexec.

projects
- argparsh
- Language agnostic argument parser
- rainbow
- Static analysis tool for C/C++ to reject invalid callgraphs, powered by
clangandCypher - Some example usecases are:
- Prevent functions that assume locks are held from being called without a lock
- Prevent functions using collective
MPIoperations from being called during another collective operation - Prevent secure functions from being called from insecure contexts
- Static analysis tool for C/C++ to reject invalid callgraphs, powered by
- video-synth
- A synthesizer for visual effects! Chain together various filters and transformations and build temporal functions to animate them. The UI is definitely a work in progress and is hard to use.
