Biography

Hi here. I am Zhang Cao (曹张 in Chinese). Now, I am an undergraduate student in Xidian University, majored in Electronic Information Engineering . My interests primarily focus on LSM-Tree based key-value stores, cache systems, LLM systems. Currently, I work as a research intern at Intelligent Data Infrastructure Lab, advised by Prof. Zhichao Cao.

Research Interests

I am widely interested in system. Former, my focus is on optimizing the Secondary Cache for LSM-KV stores. Specifically, I worked towards optimizing the existing flash-based secondary cache for LSM-KV stores and also tried to replace the regular SSDs using ZNS SSDs as the backend of the persistent cache. Currently, I'm looking to focus on storage, memory system (e.g., CXL-based memory system) and system for LLM (e.g., LLM inference).
