Disclosed is a method of controlling a server for managing movement schedules of a plurality of robots. The control method includes receiving an occupancy request for at least one node matching a scheduled moving route from at least one of the plurality of robots; setting actually occupied nodes and provisionally occupied nodes of each of the plurality of robots based on the occupancy request; and transmitting occupancy permission information including the set actually occupied node and provisionally occupied node to each of the plurality of robots. In the setting of the actually occupied node and the provisionally occupied node, the actually occupied nodes and the provisionally occupied nodes of each of the plurality of robots are selected so that an actually occupied node of one robot does not overlap an actually occupied node or a provisionally occupied node of another robot.

Provided are a method and a system for decrypting a password in multi-node parallel-processing environment including a master node and a plurality of work nodes. The master node receives information on encrypted file selection from a user. The master node generates password candidate information generation information and transmits the password candidate to the plurality of work nodes together with a password decryption command. The password candidate generation information allows the plurality of work nodes to have different password candidate ranges using password decryption information comprising a maximum password length, a minimum password length, and a string set constituting the password. The work node decrypts the password using the password candidate generation information. The work node transmits the password decryption result to the master node.
