LegoOS is a disseminated, distributed operating system designed for hardware resource disaggregation. It is an open-source project built by researchers from Purdue University. LegoOS splits traditional operating system functionalities into loosely-coupled monitors and run them directly on disggregated hardware devices. LegoOS also manages distributed resources and handles hardware component failures in a disaggregated cluster. For more information, please check out our recent awarded paper. You can get LegoOS here.
