Abstract: A distributed data processing system configured to perform distributed processing of multiple data processing processes at multiple processors includes: a data storage configured to store data to be processed through the data processing processes; a data processing section configured to cause the data processing processes to be executed; and a scheduler configured to produce a data processing schedule as a data processing procedure of the data processing processes to be executed by the data processing section based on a data processing model obtained by modeling the data processing procedure to be executed by the data processing section. The data processing section causes the processors to execute the data processing processes in accordance with the data processing procedure set in the data processing schedule.

Abstract: Provided is an information processing system that is capable of quickly starting an application program even in a case where a computer resource pool is depleted, and of completing without reducing the quality of service even in the case of an application that is ended in a short amount of time. A management server manages computer resources and a usage state of the computer resource, and in a case where no computer resources is available, and an expected execution time of the application is less than or equal to a reference value, at the time of receiving a degree of parallel and the expected execution time of the application from a user, selects computer resource executing an application having a relatively small degree of deviation from an initial expected execution time, even in a case where a plurality of applications are temporarily simultaneously executed, and arranges and executes the application.

Abstract: This server for distributing messages quickly detects a performance decline in a downstream server by using a method for keeping, for each distribution-destination server, a threshold such as a connection number and a time interval separate from a response timeout, and determining that performance has declined when the threshold is exceeded. In addition, the present invention improves system availability by identifying a server group in which performance has declined on the basis of a correlation pertaining to inter-server cooperative processing, when a distribution server exhibits a decline in performance, and by the distribution server distributing a message to a server not exhibiting a decline in performance.
