Abstract

PURPOSE:To improve system efficiency by holding the names of tasks which can be executed by respective remote computers and information on task execution loads on the remote computers for the respective remote computers and determining the computer whose execution is smallest among the remote computers which can execute a remote task by referring to the information. CONSTITUTION:An input remote task name is inputted to a data communication procedure means 1 and a remote task execution control means 3 is used to determine the name of the best remote computer which executes the remote task according to the task name. Then the remote task name and remote computer name are used to calculate the network address for data communication of the remote computer and also generate a data communication procedure required for remote task execution. Further, a data communication means 2 makes a data communication with the remote computer which executes the remote task according to the data communication procedure and outputs the remote task execution result. (Step 36). Consequently, the remote task is assigned to the best remote computer dynamically and efficiently and the remote computer executes the remote task.

FIG. 5 is a block diagram showing the configuration of this conventional remote task execution control device. 1 calculates a network address for data communication and creates a data communication procedure from the input remote task name and remote computer name. 2 is a data communication means that executes data communication with a remote computer that executes a remote task according to an input data communication procedure. In the conventional remote task execution control device configured as described above, The operation will be explained with reference to the flowchart of FIG. 6. First, the name of the remote task and the remote computer that executes the remote task are input to the data communication procedure means 1 (step 61).
).

The data communication procedure means 1 collects the name of the remote task and the network address for data communication on the remote computer (step 62), and creates the data communication procedure necessary for executing the remote task (step 63). .

The data communication means 2 executes data communication with the remote computer that executes the remote task according to this data communication procedure (step 64), and outputs the remote task execution result (step 65).

Problems to be Solved by the Invention However, with the above configuration, it is necessary to specify the remote computer on which the remote task is to be executed, and it is difficult to dynamically and efficiently execute the remote task on the optimal remote computer. In view of this problem, the present invention provides a remote task execution control device that dynamically and efficiently allocates a remote task to an optimal remote computer and causes the remote computer to execute the remote task. Means for Solving the Problems In order to achieve the above objects, the remote task execution control device ζ of the present invention includes: For each remote computer, the task name of the remote task that can be executed by that remote computer, and the name of the remote task that can be executed by that remote computer. a remote task execution control means that retains information regarding task execution load and determines a remote computer on which a remote task should be executed based on the remote task name; From the task name, a remote task execution procedure means calculates a data communication network address and creates a data communication procedure, and a remote computer executes the remote task according to the data communication procedure created by the remote task execution procedure means. According to the above-described configuration, the present invention includes a task name of a remote task that can be executed by each remote computer, and a task execution load on the remote computer. When executing a remote task, this information is used to determine the remote computer with the lightest task execution load for the remote task from among the remote computers that can execute the remote task, and the remote computer executes the remote task on that remote computer. Embodiment FIG. 2 is a system configuration diagram showing the configuration of a computer having a remote task execution control device in an embodiment of the present invention. Figure 1 is a block diagram showing the configuration of the remote task execution control device in this embodiment. The remote task execution control hand holds information regarding the task execution load on the remote computer and determines the remote computer on which the remote task should be executed based on the input remote task name. Remote task execution procedure step 2 that calculates a network address and creates a data communication procedure is a data communication means that executes data communication with a remote computer that executes a remote task according to the input data communication procedure. The entire operation of the remote task execution control device of this embodiment configured as shown in FIG. 3 will now be explained with reference to the flowchart of FIG. .

The remote task execution control means 3 is used to determine the most suitable remote computer on which to execute this remote task based on the remote task name (step 32). Calculating the network address for data communication of the remote computer (Step 3)
3) Create data communication procedures necessary for remote task execution (step 34).

The data communication means 2 executes data communication with the remote computer that executes the remote task according to this data communication procedure (step 35), and outputs the remote task execution result (step 36).

Next, the detailed operation of the remote task execution control means 3 in the remote task execution control apparatus of this embodiment will be explained with reference to the flow chart of FIG. Maintains information about the task name of a remote task and the task execution load on that remote computer.a When a remote task name is input, this information is referenced to determine the task execution load among the remote computers that can execute this remote task. The lightest remote computer is selected and each remote computer is output (step 41). Further, the following two operations are performed to update the information. Step 42) Calculates the task execution load of a remote task that can be executed by the local computer at a certain period of time using queuing theory, and sends a task execution load update request using broadcast communication as data to the local computer. and to all remote computers connected by the network (step 43).

Further, when a task execution load update request is received, the task execution load of the remote task executable by the remote computer that sent this update request in the information is updated (step 44).
).

As described above, according to this embodiment, by providing the remote task execution control means 3, there is no need to specify the remote computer that executes the remote task, and it is possible to dynamically select the remote computer that is most suitable for executing the remote task. According to the present invention, as described in the detailed explanation of the invention, it is possible to execute a remote task on that remote computer. It maintains information about the task execution load on a computer, and when executing a remote task, refers to this information and selects the remote computer with the lightest task execution load for that remote task from among the remote computers that can execute the remote task. It is possible to execute remote tasks on a computer, and the practical effect is as follows:
