In this paper, we describe a multithreaded software distributed shared memory (DSM) system named Orion. It has been developed to provide POSIX-thread (pthread) like interface. We believe this will avoid creating another unique set of application programming interface and ease the porting of pthread programs to a distributed environment. Orion implements home-based consistency model. In this paper, we also present 2 adaptive schemes for home-based DSM systems: home migration and dynamic adaptation between write-invalidation and write-update protocols. The two fully automatic schemes aim to involve minimal user intervention and yet deliver good performances with some speedups ranging from 2% to 79% observed in some 8 benchmarks tested.
