چکیده

The performance of a multicomputer system depends on the processor management strategy. Processor management deals with processor allocation and job scheduling. Most of the processor allocation and job scheduling schemes proposed in the literature incur high implementation complexity and are therefore impractical to be integrated. In this paper, we propose an integrated processor management scheme that includes a bypass-queue scheduling policy and a xed-orientation allocation algorithm. Both policies have very low complexities and are hence suitable to be integrated. Both policies improve the system performance considerably when applied in isolation. The integrated scheme provides even better performance.

Improving Performance of Mesh-connected Multicomputers by Reducing Fragmentation

Fragmentation is the main performance bottleneck of multicomputer systems. In this paper, we classify the fragmentation problems in multicomputer systems according to their causes. It is noted that among all kinds of fragmentation, physical fragmentation is seldom addressed by contemporary allocation schemes. Two novel processor allocation schemes that reduce physical fragmentation for the mesh...

An Economic Model for Resource Adaptation in 2D Mesh Multicomputer Networks

In the current partitionable Mesh-connected processors parallel machine, the system administrator (SA) can provide a means for offering the required quality of service (QoS) for a multiple classes of users. We consider the approach where the SA rents free processors in a 2D mesh-connected multicomputer with QoS guarantees for the users. Free processors are managed by the SA resource management ...

A Minimal Fragmentation Algorithm for Task Allocation in Mesh - Connected Multicomputers

—Efficient allocation of processors to incoming tasks in tightly coupled systems is crucial for achieving high performance. A good allocation algorithm should identify available processors with minimum overhead. In addition, it should be submesh recognition complete and should minimize fragmentation as far as possible. In this paper, we propose an efficient task allocation mechanism called the ...

A Quad-Tree Based Dynamic Processor Allocation Scheme for Mesh-Connected Parallel Machines

In this paper, two quad-tree (QT) baseddynamic processor allocation/deallocation heuristic algorithms are proposed for a partitionable Mesh-connected parallel multicomputer: the QTTL (Quad Tree Top Left) and the QTR (Quad Tree Root) partition first heuristics. For each QT-based algorithm, a theoretical analysis of its computational time complexity is presented in terms of the numbers of allocat...
