Embodiment 1

[0074] Next, the distributed processing system according to Embodiment 1 of the present invention will be described according to the above steps. Among them, clients such as figure 2 Indicates the desired connection task. In addition, the connection between PEs is not limited to the examples described below.

[0075] In the first described embodiment, the control unit CU transmits the information of the connection destination and the connection source of the processing element PE to each processing element PE, and constructs a path.

[0076] The conditions of the respective processing elements PE are as follows. It is assumed that TCP / IP is used in communication. However, the communication protocol is not limited to TCP / IP. Also, one processing element PE provides one task.

[0077] Table 1 shows the information of each processing element PE.

[0078] (Table 1)

[0079] Task PE address provided by PE

[0080] PE1 task 1 192.168.0.101

[0081] PE2 task 2 192.168.0.102...

Embodiment 2

[0222] Next, a distributed processing system according to Embodiment 2 of the present invention will be described. In this embodiment, the case where path information is transmitted from the client CL to each processing element PE, that is, the case where the path information is transmitted in order from the PE earlier in the execution order to the PE later in the execution order, will be described.

[0223] Wherein, the service used is the same as the aforementioned service.

[0224] In the above example in which the control unit CU sends path information to each processing unit PE, it is explained that the control unit CU first sends the path information to the previous processing unit PE, and then sequentially sends the path information to the subsequent processing unit PE. Figure 13 Indicates its program.

[0225] Figure 13 It is a diagram showing a path construction program in the case where transmission is performed in order from the processing element PE that is exe...

Embodiment 3

[0231] Next, a distributed processing system according to Embodiment 3 of the present invention will be described. In this embodiment, a case will be described in which path information is transmitted from the control unit CU to all the processing elements PE by broadcast.

[0232] The services used are the same as those described above.

[0233] A case where the control unit CU transmits path information to all the processing elements PE used in the service by broadcasting once and then constructs paths will be described.

[0234] Figure 14 Shows a program for constructing a route when transmitting route information by broadcast.

[0235] The control unit CU sends path information to all the processing elements PE constituting the path by broadcasting.

[0236] Each processing element PE that has received the route information is connected to the output destination, and also accepts the connection of the input processing element PE.

[0237] Each processing element PE se...

Abstract

A distributed processing system includes a plurality of processing elements each having one or more inputs and one or more outputs, and a control unit to which the plurality of processing elements are connected, wherein based on a service execution request from a client, the control unit creates execution transition information in which the processing elements that are necessary to execute a specific service and an order of execution are specified.

Description

technical field [0001] The present invention relates to distributed processing systems. Background technique [0002] Conventionally, in stream distributed processing, for a group of processing elements (hereinafter appropriately referred to as "PE") used in the processing, a control unit (hereinafter appropriately referred to as "CU") that determines the path is passed to the processing Communication of components in a broadcast or one-to-one manner to establish processing paths. Such processing is proposed, for example, in Japanese Patent Application Laid-Open No. 6-162228. [0003] However, conventionally, each processing unit has one input and one output. Therefore, it cannot cope with the use of processing elements having multiple inputs and multiple outputs. Contents of the invention [0004] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a distributed processing system capable of constr...
