According to the method, the characteristics capable of accurately describing the job application attributes are mined, and a good prediction improvement effect is achieved; a machine learning algorithm is adopted to find an operation failure prediction method, the robustness of a prediction model is improved, and the method is especially suitable for nonlinear data; the clustering calculation overhead is remarkably reduced and the error is reduced by adopting a clustering method for the job application attributes; the prediction efficiency is high, and the method can be practically applied to large supercomputers.

Description

technical field [0001] The invention relates to the field of supercomputers, and more specifically, to a method for actively predicting job failures of supercomputers based on application similarity. Background technique [0002] A large number of jobs are submitted and waiting to be executed in the supercomputer, but during the execution of the job, the job may fail due to various reasons, such as system resources cannot meet the job requirements, memory errors, and software and hardware failures. At the same time, job failure will cause waste of system resources, prolong the waiting time of jobs in the queue and other adverse effects. The use of job failure prediction can be used to slow down the impact of these failures. Therefore, how to effectively predict job failure is crucial to improving system reliability and System resource utilization is critical. [0003] At present, there are many prediction methods for software and hardware failures of supercomputers (high-pe...
