Low Latency Messages on Distributed Memory Multiprocessors
This paper describes many of the issues in developing an efficient interface for comnaunication on distributed memory machines and proposes a portable interface. Although the hardware component of message latency is less than one microsecond on many distributed memory machines, the software latency associated with sending and receiving typed messages is on the order of 50 microseconds. The reas...
متن کاملMemory Latency in Distributed Shared-Memory Multiprocessors
Analytical models were developed and simulations of memory latency were performed for Uniform Memory Access (UMA), Non-Uniform Memory Access (NUMA), Local-Remote-Global (LRG), and Replicated Concurrent-Read ( R C R ) architectures for hit rates from 0.1 to 0.9 in steps of 0.1, memory access times of 10 nsec to 100 nsec, proportions of read/write access from 0.01 to 0.1, and block sizes of 8 to ...
متن کاملSystem Software Support for Reducing Memory Latency on Distributed Shared Memory Multiprocessors
This paper overviews results from our recent work on building customized system software support for Distributed Shared Memory Multiprocessors. The mechanisms and policies outlined in this paper are connected with a single conceptual thread: they all attempt to reduce the memory latency of parallel programs by optimizing critical system services, while hiding the complex architectural details o...
متن کاملDynamic Scheduling on Distributed-Memory Multiprocessors
The problem of scheduling a set of applications on a multiprocessor system has been investigated in a number of diierent points of view. This paper describes our work on the scheduling problem at the user level, where we have to distribute evenly the parallel tasks that compose a program among a set of processors. We investigated dynamic scheduling heuristics applied to loops on distributed-mem...
متن کاملThread Migration on Distributed-memory Multiprocessors
Executing multi-threaded programs on multiproces-sors can exploit the inherent parallelism among threads. However, the load imbalance and frequent remote data access factors may degrade the performance in distributed-memory parallel systems. To cope with these problems, one of the solutions is to enhance threads with dynamic migration capability. This paper describes our experiences with the de...
