Worked on the scroll-tech/ceno repository to deliver GPU-accelerated proof generation and high-throughput chip proving, focusing on memory-aware scheduling and concurrent execution. Leveraged C++, Rust, and CUDA to implement a GPU prover, optimize batch sumcheck operations, and refactor the proving pipeline for safe parallelism using per-thread CUDA streams. Enhanced memory management by introducing configurable GPU cache levels and memory estimation, reducing buffer usage and improving throughput. Improved code maintainability through API cleanup, documentation, and cross-repo alignment. The work resulted in measurable performance gains, streamlined deployment, and greater scalability for zero-knowledge proof workloads on GPU-enabled infrastructure without introducing new bugs.
