Abstract: A computing system includes a host device and an acceleration device. The host device is in a communication connection with the acceleration device. The host device is configured to send invocation information to the acceleration device. The invocation information indicates a storage address of the first data. The acceleration device is configured to receive the invocation information from the host device, obtain the first data from a memory based on the storage address, and perform the to-be-processed task based on the first data to obtain a processing result. The host device notifies the acceleration device of the storage address, and the acceleration device directly obtains the data from the memory based on the storage address such that the host device is prevented from obtaining the data from the memory.

Abstract: A first cluster and a second cluster include at least one single-threaded main controller, the at least one single-threaded main controller processes one access request requesting for data at a time, and the data accessed by the access request is jointly managed by the first cluster and the second cluster. A database server determines hot data managed by the first cluster and determines whether a migration condition for migrating the hot data to the second cluster is met. The second cluster manages hot data that meets the migration condition. The database server migrates the hot data that meets the migration condition to the second cluster and triggers an update of an access path of the hot data.
