Abstract :
The authors describe a multithreaded software distributed shared memory, (DSM) system named Orion. It has been developed to provide a POSIX-thread (pthread) like interface. We believe this will avoid creating another unique set of application programming interfaces and ease the porting of pthread programs to a distributed environment. Orion implements a home based consistency model. We also present 2 adaptive schemes for home based DSM systems: home migration and dynamic adaptation between write-invalidation and require-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
