Embodiment Construction

[0017] Considering the problems existing in the related technologies, the present invention provides a real-time job scheduling system and method. Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. It should be understood that the embodiments described below by referring to the figures are exemplary only for explaining the present invention, and should not be construed as limiting the present invention.

[0018] figure 1 It is a flow chart of the real-time job scheduling method according to the present invention, such as figure 1 As shown, the method includes the following steps:

[0019] Step S110, creating multiple queues.

[0020] Step S120, setting multiple queues to different priority levels, and setting the preemptiveness of the queues according to the priority levels.

[0021] Specifically, in the embodiment of the present invention, an adaptive algorithm is used to set the priority level and p...

Abstract

The invention provides a real-time operation dispatching system and a method thereof. The method includes following steps of creating a pluralities of queues, setting the queues into different priority levels, setting preemption of the queues according to the priority, judging whether a real-time operation is existed or not, if not, then executing the existing operation continuously, if so, then hanging up the existing operation, releasing applied resources of the existing operation, and then executing the real-time operation on a server. After finishing the real-time operation, the existing operation which is hung up is operated continuously on the server. The real-time operation dispatching system and the method thereof utilize a priority dispatching mechanism and a preemption mechanism, thereby realizing real-time of application software.

Description

technical field [0001] The invention relates to the high-performance field of computer technology, in particular to a job scheduling system and method. Background technique [0002] At present, high-performance servers have been widely used in scientific research, government and defense departments, and application software on high-performance servers is becoming more and more popular. The simultaneous operation of multiple application software will cause resource conflicts and affect the performance of some software. For example, real-time software has very strong requirements for corresponding time. In some cases, the results of real-time tasks exceeding the deadline will be invalid. As a result, such as weather software, weather data exceeding the specified time will be regarded as invalid data. [0003] The existing job scheduling system adopts a fair scheduling strategy without introducing the concept of priority, and cannot guarantee the fast operation of real-time so...
