Heavy-traffic limits for an infinite-server fork-join queueing system with dependent and disruptive services
We study an infinite-server fork-join queueing system with dependent services, which experiences alternating renewal service disruptions. Jobs are forked into a fixed number of parallel tasks upon arrival and processed at the corresponding parallel service stations with multiple servers. Synchronization of a job occurs when its parallel tasks are completed, i.e., non-exchangeable. Service times...
متن کاملComputing Performance Bounds for Fork-Join Queueing Models
We study a computer system which accepts parallel programs which can be modeled using the fork-join computational paradigm. The system under study has K homogeneous servers, each having an in nite capacity queue. Jobs arrive to the system according to a general interarrival process with mean arrival rate . Upon arrival, the job is split into K independent tasks ti; 1 i K and task ti is assigned...
متن کاملMonotonicity Properties and Simple Bounds on the Mean Cycle Time in Acyclic Fork-Join Queueing Networks
The (max,+ )-algebra approach is applied to establish some monotonicity properties and to get algebraic bounds on the service cycle completion times in acyclic fork-join queueing networks. The obtained results are extended to derive simple lower and upper bounds on the mean cycle time in stochastic networks.
متن کاملModelling Zoned RAID Systems Using Fork-Join Queueing Simulation
Abstract. RAID systems are ubiquitously deployed in storage environments, both as standalone storage solutions and as fundamental components of virtualised storage platforms. Accurate models of their performance are crucial to delivering storage infrastructures that meet given quality of service requirements. To this end, this paper presents a flexible fork-join queueing simulation model of RAI...
متن کاملAlgebraic modelling and performance evaluation of acyclic fork-join queueing networks
Simple lower and upper bounds on mean cycle time in stochastic acyclic fork-join queueing networks are derived using a (max,+)algebra based representation of network dynamics. The behaviour of the bounds under various assumptions concerning the service times in the networks is discussed, and related numerical examples are presented. Key-Words: (max,+)-algebra, dynamic state equation, acyclic fo...
