Computing system and server
A storage device, connected to a computer including a processor and first memory, and executing a program, stores data processed under the program. The computer includes a protocol processing unit that accesses data in the storage device, an accelerator that includes an arithmetic unit executing a part of a process of the program, and a second memory storing data, and executes the part of the process. The first memory receives a processing request for processing data, and causes the accelerator to execute a command to process data, corresponding to the processing request for the processing request including a process to be executed by the arithmetic unit. The accelerator requests the protocol processing unit to provide target data indicated by a command received from the program, reads data from the storage device via the protocol processing unit, and stores the data in the second memory. The arithmetic unit executes the command.
