To provide a network corresponding distributed processing system for realizing an operation rate equal to a multiprocessor computer.

The network corresponding distributed processing system is provided with a program supply server 2 having a storage device 2c storing a task program group 22 which is referred to when distributed processing is performed, a plurality of workstations 3, 4, 5 performing the distributed processing by referring to the task program group 22, and a network 7 connecting the program supply server 2 and the plurality of the workstations 3, 4, 5. Each of workstations 3, 4, 5 has first semiconductor storage device 32 storing a starting program for controlling self-starting processing and a second semiconductor storage device 33 storing a task program 22', 22-1 to 22-n. The workstations 3, 4, 5 download the prescribed task programs 22-1 to 22-n from the task program group 22 of the program supply server 2 through the network 7 and refer them.
