Fork-Join Program Response Time on Multiprocessors with Exchangeable Join
A Fork-Join program is one that consist of k ≥ 1 parallel tasks, which is a reasonable model for a large number of computing applications. When the parallel processor have multi-channels, later arrived tasks may finish executions earlier than the early arrived tasks and may join with the finished tasks from different programs. This phenomenon introduce correlation to tasks service times and is ...
متن کاملFormalization of Workflows Using Fork-Join Automata
We survey the current practice of using workflows for business process modeling and we present a simple formalism for reasoning about the structural correctness of fork–join workflow diagrams containing and and or nodes. Introduction. Currently Business Process Management (BPM) is an important issue in the organization of enterprises. Various formalism and tools suport computer aided BPM, and t...
متن کاملHigher Moment Approximation of Fork / Join
In this paper we present an approximate analysis of fork/join prim-itives with two parallel servers, limited buuers and non-zero join times where either jobs arrive according to a Poisson process (open system) or the number of jobs is limited according to the CONWIP rule (closed system). The approximation method is based on the concept of ow-equivalent servers and enables the approximate analys...
متن کاملResponse Time Approximations in Fork-Join Queues
Fork-join queueing networks model a network of parallel servers in which an arriving job splits into a number of subtasks that are serviced in parallel. Fork-join queues can be used to model disk arrays. A response time approximation of the fork-join queue is presented that attempts to comply with the additional constraints of modelling a disk array. This approximation is compared with existing...
متن کاملPerfect Sampling for Fork-Join networks
In this paper, we show how to design a perfect simulation for Markovian fork-join networks, or equivalently, free-choice Petri nets. For pure fork-join networks and for event graphs, the simulation time can be greatly reduced by using extremal initial states, namely blocking states, although such nets do not exhibit any natural monotonicity property. Another approach for perfect simulation of p...
