| Abstract | This paper overviews results from our recent work on buildin g customized system software support for Distributed Shared Memory Multiprocessor . The mechanisms and policies outlined in this paper are connected with a single conce ptual thread: they all attempt to reduce the memory latency of parallel programs by optimiz ing critical system services, while hiding the complex architectural details of Distribu ted Shared Memory from the programmer. We present four techniques that exhibit solid p erformance improvements: Efficient memory management for lightweight multithreadin g, highly scalable hybrid synchronization primitives, a virtual memory management sche me for DSM systems and transparent operating system services for adapting parall el programs to multiprogrammed environments. |
