We think, we innovate and we work as a team. OSLab @ KAIST is committed to redefine the way in which the modern OS plays. We overhaul the modern operating system to make it further efficient and scalable. In particular, we dedicate our effort to make the OS ready to the newly emerging hardware technologies such as manycore CPU, peta-byte scale main memory, byte-addressable NVRAM, multi-queue NVMe storage, and etc. We aim at making the OS better support the modern applications such as Machine Learning application, Block-Chain application, key-value engines and etc.
