Problems solved by technology

[0007] The purpose of the present invention is to solve the problem that the existing data acquisition program and the program monitored by TAU compete with each other for system resources, resulting in too long running time of the program after insertion, the measured data is affected by resource competition, and the actual program running process cannot be completely restored question

Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] see figure 1 As shown, the cluster system based on the Infiniband network and the Luster system, wherein the Luster system includes an I / O information statistics node 4, a first I / O information passive collection node 1, and a second I / O information passive Collection node 2 and passive collection node 3 of the Nth I / O information. The cluster system includes a first program execution node 5 , a second program execution node 6 and an Nth program execution node 7 . The program execution node is used to obtain the program running Trace file (trace file) by running the program inserted by the TAU.

[0021] In the system based on Infiniband network and Luster, the storage information collection service step S1, the Infiniband network congestion detection service step S2 and the file dump service step S3 are adopted to realize the Trace fi...

Abstract

The invention discloses a Trace file dump method for reducing resource competition. In an Infiniband network and a Luster system, the dump method executes three service steps, namely storage information collection service S1, Infiniband network congestion detection service S2 and file Dump service S3. This method combines the passive detection of the IO usage of the Luster system with the active detection of the Infiniband network usage, calculates the congestion of the network and IO resources, and dumps the trace files when there is no congestion, so as to reduce the number of trace file transfers. The resource competition between the storage and the monitored program occurs, and the technical effect of faster running speed and more accurate trace data is obtained after the program is inserted.

Description

technical field [0001] The invention relates to a method for dumping trace files (ie Trace files) in a cluster, more particularly, a method for dumping trace files that reduces resource competition. In particular, it involves the dumping process of TAU (Tuning and Analysis Utilities, translation, debugging and analysis tool) software in the cluster environment using Infiniband (translation, unlimited bandwidth) network and Luster (translation, glossy file system) system. Background technique [0002] A cluster is a collection of multiple independent computers connected to each other. These computers can be stand-alone or multi-processor systems, such as PCs or workstations. Each node has its own memory, IO (Input / Output, translation, input and output) device and operating system. The cluster is a single system for users and applications, which can provide low-cost, high-efficiency, high-performance environments and fast and reliable services. [0003] Infiniband network is...
