Abstract: A method includes: receiving a fast Fourier transformation FFT execution request sent by an application program; obtaining first input data on which an FFT calculation needs to be performed; decomposing the FFT calculation into a plurality of calculation stages based on a cardinality of the FFT calculation, where each calculation stage includes a DFT calculation; determining a DFT calculation matrix corresponding to the DFT calculation in each calculation stage; determining, based on input data of a corresponding calculation stage when a calculation of each calculation stage is performed, a first data matrix on which a matrix operation is performed with the DFT calculation matrix; and performing a matrix multiplication calculation on the DFT calculation matrix and the first data matrix to implement the DFT calculation, and returning a calculation result to the application program after the plurality of calculation stages are completed.

Abstract: A scheduler obtains a to-be-processed job; and controls at least one super node based on a resource requirement of the to-be-processed job to process the to-be-processed job based on a global memory pool of the super node, where the to-be-processed job is a processing request related to a distributed application. In this way, because the global memory pool is a resource that is constructed through unified addressing on storage media of nodes in the super node and that is shared by the nodes in the super node, the nodes in the super node that are coupled using a high-speed interconnection technology share and access the global memory pool to process the to-be-processed job.
