Hello there! I am a research scholar at IIT Bombay, working in the field of compilers and programming languages. I have experience on working with real world JIT compilers. In addition to my research, I am passionate about coding in React and have utilized it in creating websites, such as this one. Beyond my computer science pursuits, I enjoy tinkering with Raspberry Pi's and Arduinos during my free time.

Always looking forward to new emails :)


PhD @ IIT Bombay, second semester
Updated: 9th Feb 2024

I am currently doing a literature survey. Looking into topics such as dependent types, dynamic deoptimization and debugging.

[OOPSLA 2023] Reusing Just-in-Time Compiled Code
16th October 2023

Most code is executed more than once. If not entire programs then libraries remain unchanged from one run to the next. Just-in-time compilers expend considerable effort gathering insights about code they compiled many times, and often end up generating the same binary over and over again. We explore how to reuse compiled code across runs of different programs to reduce warm-up costs of dynamic languages. We propose to use speculative contextual dispatch to select versions of functions from an off-line curated code repository. That repository is a persistent database of previously compiled functions indexed by the context under which they were compiled. The repository is curated to remove redundant code and to optimize dispatch. We assess practicality by extending Ř, a compiler for the R language, and evaluating its performance. Our results suggest that the approach improves warmup times while preserving peak performance.
