Abstract

The invention discloses a cluster task dispatching manager used for multi-grid access. Tasks on a cluster system are divided into local tasks and grid tasks, and a grid corresponding to the grid task is determined.Priority classification is carried out on the tasks, so as to ensure that cluster resource is allocated to the tasks according to task priority while the tasks are submitted. Meanwhile local task reservation resource occupying strategy is adopted, so as to ensure that the task from the grid can not contend cluster resource with the local task within valid reservation holding time when the local task has a great demand on resource. On the basis, a task dispatching and resource allocation strategy algorithm is provided, so as to ensure that required resource is timely and effectively allocated to the task. The invention can cause cluster task dispatching and management to be adaptive to that a cluster is simultaneously accessed by multiple grid systems, availability factor of cluster resource is fully improved, and task dispatching and management of cluster system are more flexible and convenient.

Description

technical field [0001] The invention relates to a cluster task scheduling manager serving multi-grid access, belonging to the technical field of grid-connected computer cluster scheduling management. Background technique [0002] The development trend of high-performance computers is changing from traditional dedicated supercomputer platforms to low-cost, general-purpose, loosely coupled cluster systems consisting of single or multiple processor computers or workstations. This kind of cluster system has many advantages, including the ability to build platforms according to a given task to accommodate larger applications and workloads. Many units have purchased or developed high-performance computing cluster systems due to the needs of scientific research and work, and purchased related system software and application software used on the cluster. However, these units all face a problem in the management and maintenance of the cluster, which is the resource utilization of th...
