SYSTÈME INFORMATIQUE RÉPARTI, PROCÉDÉ ET DISPOSITIF DE TRANSMISSION DE DONNÉES DANS UN SYSTÈME INFORMATIQUE RÉPARTI

摘要

This application discloses a distributed computing system. Both a first computing node and a second computing node in the distributed computing system store information about a name, a size, and a communication peer identifier of a first data flow graph parameter in a data flow graph, the first computing node stores the first data flow graph parameter, the first computing node and the second computing node generate respective triplets by using respective same interface parameter generation algorithms and information about the first data flow graph parameter that are stored in the nodes. The triplet is used as an interface parameter of a message passing interface MPI primitive that is used to transmit the first data flow graph parameter between the first computing node and the second computing node. In this way, the first computing node and the second computing node may transmit a data flow graph parameter by using an MPI primitive without negotiation. This can improve efficiency of data communication between computing nodes, to improve efficiency of computing a data flow graph by the distributed computing system.
