Abstract: A method of predicting GPU malfunctions includes installing a daemon program at a GPU node, the daemon program periodically collecting GPU status parameters corresponding to the GPU node at a pre-determined time period. The method also includes obtaining the GPU status parameters from the GPU node and comparing the obtained GPU status parameters with mean status fault parameters to determine whether the GPU is to malfunction, where the mean status fault parameters are obtained by use of a pre-configured statistical model. Prior to a GPU enters a malfunction state, the GPU can be replaced, or the programs executing on the GPU can be migrated to other GPUs for execution, without affecting the normal business operations.
