The Prospects for Parallel Programs on Distributed Systems
نویسنده
چکیده
Programmers want shared memory. They can get it on special-purpose multiprocessor architectures, but the speed of technological improvements makes it difficult for these architectures to compete with systems built from commodity parts. Shared-memory parallel programming on distributed systems is therefore an appealing idea, but it isn’t practical yet. Practicality will hinge on a prudent mix of compiler technology, dynamic data placement with relaxed consistency, and simple hardware support.

متن کاملAN OPTIMAL FUZZY SLIDING MODE CONTROLLER DESIGN BASED ON PARTICLE SWARM OPTIMIZATION AND USING SCALAR SIGN FUNCTION
This paper addresses the problems caused by an inappropriate selection of sliding surface parameters in fuzzy sliding mode controllers via an optimization approach. In particular, the proposed method employs the parallel distributed compensator scheme to design the state feedback based control law. The controller gains are determined in offline mode via a linear quadratic regular. The particle ...
متن کاملThe Effects of Excitation Control Systems on Parallel Operation of DGs with the Main Grid
This paper presents actual cases of steady reactive power oscillation of Distributed Generations (DGs) during parallel operation with the main grid. The cause of the problem was found to be the adverse effects of excitation system voltage regulation. It is shown, through preliminary investigation and detailed simulation studies, that how the excitation control system can be modified to overcome...
متن کاملCold standby redundancy optimization for nonrepairable series-parallel systems: Erlang time to failure distribution
In modeling a cold standby redundancy allocation problem (RAP) with imperfect switching mechanism, deriving a closed form version of a system reliability is too difficult. A convenient lower bound on system reliability is proposed and this approximation is widely used as a part of objective function for a system reliability maximization problem in the literature. Considering this lower bound do...
