Embodiment approach

[0052] Figure 7 An example of the configuration and functionality of the distributed computing system 100 is illustrated. In this embodiment, a distributed computing system 100 is provided with a request node computer 3 and a plurality of execution node computers 1 (1A and 1B). It should be noted that the distributed computing system 100 may not include the requesting node computer 3 . In other words, the request node computer 3 may be provided outside the distributed computing system 100 . In addition, the number of execution node computers 1 is not particularly limited.

[0053] The request node computer 3 includes a processing manager 31 , a request unit 32 , an authentication unit 33 and a communication unit 34 . Here, the requesting node computer 3 may be included in Figure 7 Other functions not shown in the example.

[0054] The process manager 31 manages applications to be executed by the execution node computer 1 using the process list. Note that an application...

Abstract

The invention provides a communication device and a communication method used in distributed computing environment. A communication device among a plurality of communication devices is used in a distributed computing system. The distributed computing system executes a target process including a plurality of partial processes by using the plurality of communication devices. The communication deviceincludes a memory, a selector, an execution unit and a trail manager. The memory stores a trail that represents a state of the plurality of partial processes. The selector selects, from among the plurality of partial processes, an uncompleted partial process with a number of equivalent execution results being less than a target number according to the trail. The execution unit executes the uncompleted partial process selected by the selector. The trail manager records an execution result obtained by the execution unit in the trail.

Description

technical field [0001] Embodiments discussed herein relate to communication devices and communication methods for use in a distributed computing environment. Background technique [0002] Distributed computing has been proposed as one of technologies for performing large-volume computing without using a mainframe computer. In distributed computing, a program is divided into multiple program components, and the multiple program components are executed by multiple computers. At this time, the plurality of computers perform calculations as a whole while communicating with each other through a network. [0003] As an example of distributed computing, voluntary computing has been put into practical use. Voluntary computing uses distributed spare computing resources to perform a given process. For example, volunteer computing could be used to search for intelligent life outside Earth. [0004] figure 1 An example of a conventional distributed computing system is illustrated. ...
