Embodiment Construction

[0034] The technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Apparently, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0035] As mentioned in the background technology, in the existing disk management strategy, disk selection is only performed according to the remaining space of the disk. Therefore, when there are heterogeneous disks with large performance differences, or disks with large differences in size, Reasonable management of the disk cannot be realized, specifically, based on such as figure 2 As shown in the processing flow, the defects of the existing disk management strategy are mainly manifest...

Abstract

The embodiment of the invention discloses a multiple disc management method and multiple disc management equipment. By adopting the technical scheme provided by the embodiment of the invention, the selection of discs for each task requires the free space of all discs to be taken into consideration and also requires the performance information of the discs to be taken into consideration in order to determine the priority parameters of the discs, wherein the discs are selected for the task according to the priority parameter; therefore, the disc management is more effective and the performance of the disc is played.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a disk management method and device in a multi-disk scenario. Background technique [0002] Parallel computing (Parallel Computing) refers to the process of using multiple computing resources to solve computing problems at the same time. Parallel computing or parallel computing is relative to serial computing. The so-called parallel computing can be divided into parallel in time and parallel in space. Parallelism in time refers to pipeline technology, while parallelism in space refers to the concurrent execution of calculations with multiple processors. [0003] Parallel computing systems, such as MapReduce, Pregel, MPI, OpenMP, etc., provide a parallel and distributed processing method for high-performance computing and massive data processing. This type of system is generally composed of a large number of processing nodes and central control nodes. The central...
