Abstract

PURPOSE:To distribute the load of individual work stations by allowing a work station having an optimum environment to execute a program requested to be executed. CONSTITUTION:A client 2 is provided an environment informly control part 6 for informing the using state of a memory 7 to a server 4 through a data transfer control part 5. A client 3 is also provided with an environment informing control part 9 for informing the using state of a memory 10 to the server 4 through a data transfer control part 8. At the time of receiving the using states of the memories 7, 10 informed from respective clients 2, 3 and then receiving a program execution request from one of the clients 2, 3, the server 4 selects an optimum work station based on the using states of the memories 7, 10, 13 and includes an environment monitor and control part to 12 load the program to the selected work station.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a workstation network including a transmission line and a plurality of clients and servers which communicate with each other via the transmission line.

[0002]

2. Description of the Related Art In a conventional workstation network, when a server receives a program execution request from a client, a first method for executing the program in the server and receiving the result from the server, and a client downloading the program from the server. A second method is employed, which is performed in the client.

[0003]

However, the above-mentioned first method has a drawback that the load of the server increases as the number of clients connected to the network increases. Further, the second method has a drawback that the load on the client increases as the number of programs executed in the client increases.

An object of the present invention is to provide a workstation network in which a program requested to be executed is executed by a workstation having an optimum environment and the load of each workstation is distributed.

[0005]

In order to achieve the above object, in a workstation network of the present invention, each client has an environment notification control in which each client notifies the server of its own environment via a data transfer control unit and a transmission path. When the server receives the environment notified from each client via the data transfer control unit and receives a program execution request from a client via the data transfer control unit, the server notifies each client of the notified environment. It has an environment monitoring control unit which selects a workstation having an environment optimal for executing the program from the environment and the environment in the server and loads the program on the workstation.

[0006]

Since the program requested to be executed is executed by the workstation having the optimum environment, the load on each workstation can be distributed.

[0007]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is an overall configuration diagram of a workstation network according to an embodiment of the present invention, and FIG. 2 (1), (2),
(3) is a configuration diagram of the client 2, client 3, and server 4, respectively, FIG. 3 (1) is a diagram showing memory capacities of the clients 2, 3 and server 4, and FIG. 3 (2) is a diagram showing a sequence example. ..

The workstation network of this embodiment, as shown in FIG. 1, includes a transmission line 1, clients 2, 3 and a server 4 which communicate with each other via the transmission line 1.
It is composed of.

As shown in FIG. 2A, the client 2 transmits data on the transmission line 1 and receives data on the transmission line 1, a memory 7, a client 7, and a client 2. The environment notification control unit 6 notifies the server 7 of the usage status of the memory 7, which is the environment, via the data transfer control unit 5. The client 3 is shown in FIG.
As shown in (2), the data transfer control unit 8, the memory 10, and the environment notification control unit 9 are exactly the same as the client 2. As shown in FIG. 2C, the server 4 transmits data on the transmission line 1 and receives data on the transmission line 1, a data transfer control unit 11, a memory 13, and clients 2 and 3. Memory 7, 10 that is the notified environment
When the usage status of the client is received via the data transfer control unit 11 and a program execution request from a client is received via the data transfer control unit 11, the notified environment of each client 2 and 3 and the environment inside the server 4 are notified. It is composed of an environment monitoring control unit 12 which selects a workstation having an optimal environment for execution of the program from (the usage status of the memory 13) and loads the program on the workstation.

Next, the operation of this embodiment will be described with reference to FIG.

Here, it is assumed that the relationships among the capacities of the memories 7, 10 and 13 are as follows.

Memory 7 <Memory 13 <Memory 10 Referring to FIG. 3 (2), the server 4 receives the environment notification from the clients 2 and 3 in advance (S 1, S 2), and the transmission line 1
Is aware of the environment of the workstation connected to. When the server 4 receives the program execution request (S3) from the client 2, the server 4 compares the environment (memory usage status) notified in advance with the environment (memory usage status) in the server 4, and selects an environment suitable for program execution. A workstation that has a client, which has the largest unused memory capacity in this embodiment, is selected, and the program is executed by the client 3.
(S4). After the completion of the program loading, the server 4 gives an execution start request (S5). Client 3
Notifies the server 4 that the memory capacity has changed due to the execution of the program (S6).

[0014]

As described above, according to the present invention, the environment monitoring control unit for monitoring the environment of each workstation is installed in the server, the environment of each workstation is recognized, and the program requested to be executed is optimized in the optimal environment. Running on workstations with has the effect of balancing the load on individual workstations.
