The invention discloses a computing
system, a control method, a control device, equipment, a medium and a switch, and relates to the technical field of computers, in a multi-
machine multi-card cluster comprising a plurality of computing equipment, a first switch is adopted to realize
interconnection between southbound interfaces of different acceleration cards, and the first switch comprises a first controller and a
bus bridge, the
bus bridge is connected with a southbound interface of the acceleration card, the first controller is used for distributing a southbound address for the acceleration card and configuring routing information of the
bus bridge, so that the acceleration card carries out data forwarding based on the southbound address, and the bus bridge carries out data forwarding among southbound interfaces of different acceleration cards according to the routing information. According to the method and the device, any cross-host accelerator card does not need to be forwarded through a
northbound interface during communication, and does not need to be appointed by upper
software, so that the problems of relatively long communication path and communication blockage in related technologies are solved, and the communication efficiency of
interconnection of the accelerator cards in a multi-host multi-card cluster is improved.
