I’m a 6th year graduate student at Princeton University advised by Prof. David I. August. I’m currently working on CPU microarchitecture with a focus on improving performance of CPU front-end for datacenter workloads. My broader interests include Computer Architecture, Microarchitecture, Systems, Compilers, Program Analysis, Programming Languages, Security. I work on improving performance of the whole application stack from hardware to software. During the course of my PhD I worked on LLVM compiler and gem5 architectural simulator. I have built several tools to enable fast checkpointing of multithreaded application using real hardware for ARM architecture (using Raspberry Pi and Apple’s M1 Mac).
I did my undergrad in Computer Science from Indian Institute of Technology, Hyderabad (IIT, Hyderabad). After graduating from IITH, I joined compilers team in AMD India, Bangalore. I worked on AOCC( AMD Optimizing C and C++ Compiler) which is based on LLVM Compiler. I worked on several compiler optimizations such as Loop Vectorization, Loop Distribution, Loop Independent Code Motion, Macroop Fusion, Branch Combine, etc.
