Problems solved by technology

However, in the current testing process of these test software, due to different machine configurations or external environmental influences, the execution time of individual test commands is inconsistent.
As a result, the start time of subsequent test commands on multiple test machines is misaligned, which affects test accuracy

Embodiment Construction

[0035] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] The present invention provides a method for synchronously testing the performance of a parallel file system in a cluster. The basic idea is that, by subtly maintaining information indicating the test execution status of each test machine in a shared file directory, each test machine After a test, detect the information in the shared directory to indicate the test execution status of other test machines, and only execute the next test when it is detected that all test machines have completed the test, so that it is simple and convenient to implement Synchronous work for large number of cluster performance tests.

[0037] see figure 2 , which shows a method for synchronously testing the performance of a cluster parallel file system according to an embodiment of the present invention, including the following steps:

[0038] Step S201: using shel...

Abstract

The invention provides a method and a device thereof for synchronically testing the performance of a cluster parallel file system. The synchronic test cluster parallel file system comprises a plurality of testers. The method comprises the following steps that: each tester in the cluster parallel file system maintains a message which is used for indicating the test execution situation in a shared directory of the cluster parallel file system; and after the tester executes one item of test, the message in the shared directory for indicating the test execution situation of other testers is firstly detected, and the next item of test is executed after detecting that all testers complete the item of the test. The method can simply and conveniently realize the synchronic work of the performance test of clusters with substantial quantity.

Description

technical field [0001] The invention relates to a development and testing method and device for a cluster parallel file system. Background technique [0002] At present, the development of the cluster has entered a new stage, and the application of the cluster parallel file system has made long-term progress, especially for the development of the current open source parallel file system. Luster is an open source, cluster parallel file system based on object storage technology. It has high scalability, availability, performance, ease of use, etc., and is widely used in high-performance computing systems. Cluster parallel file system network structure such as figure 1 As shown, it mainly includes three parts: a metadata server (Metadata Server, referred to as MDS), an object storage server (Object Storage Server, referred to as OSS), and a client (Client). [0003] The main purpose of cluster technology development is to improve the performance of computer systems. For R&D ...
