The study of operating system mechanisms and policies for the                   management of various levels of shared storage in tightly-coupled MIMD          machines is at an early stage.  This is even more true for the case of          large-scale machines with hundreds of processors.  These issues are             investigated in the large-scale with a focus on the Butterfly                   multiprocessor.  Specific projects divide into the following classes:           shared data migration across parallel main memories, management of              virtual memory in a setting of multiple secondary memories each                 associated with a main memory, file systems design, and the design and          evaluation of distributed, concurrent data structures (which are                crucial components in the implementation of systems responsible for             shared memory management).
