Abstract: A method is applied to a compute node including a first storage medium and a second storage medium, a data access rate of the first storage medium is greater than a data access rate of the second storage medium which stores metadata of a first dataset, the first dataset is stored in a storage system connected to the compute node via a network. The method includes: obtaining a first input/output request; searching the first storage medium for metadata of first data based on the first input/output request; obtaining the metadata of the first data from the second storage medium when the metadata of the first data is not found in the first storage medium; and obtaining the first data from the storage system based on the metadata of the first data.

Abstract: A computing cluster includes a plurality of computing nodes. A method includes: obtaining an execution characteristic parameter of an application; obtaining, based on the execution characteristic parameter of the application and a load model, running time periods of the application when the application runs on different computing nodes, where the different computing nodes have different configurations; and determining, according to a preset policy, a configuration of a computing node that executes the application.
