Abstract

In an apparatus for resource management, a resource bidding unit calculates a bid price indicating a virtual price of a resource for each of application programs to consume or supply within a predetermined unit-time, and makes a bidding by inputting the calculated bid price. A bidding management unit allocates a resource per unit-time to each of the application programs based on the bid price input by the resource bidding unit. Moreover, the resource bidding unit determines a state of an application program whether active or inactive, and calculates the bid price to allocate the resource preferentially to an active application program rather than an inactive application program.

Claims

1. An apparatus for allocating a resource, the apparatus comprising:

a discriminating unit that discriminates each of a plurality of application programs into one of an active application program or an inactive application program;

a bid-price calculating unit that calculates a bid price indicating a virtual price of a resource in a bidding to be a value at which the resource is to be preferentially allocated to the active application program rather than the inactive application program; and

a bidding management unit that allocates the resource to each of the application programs based on the bid price calculated by the bid-price calculating unit.

2. The apparatus according to claim 1, wherein

the bid-price calculating unit calculates the bid price of the inactive application program to be larger than the bid price of the active application program, and

the bidding management unit allocates the resource preferentially to an application program that has a bid price smaller than that of another application program.

3. The apparatus according to claim 1, wherein the bid-price calculating unit is provided as a plurality of units, each of which is provided correspondingly to each of the application programs, and calculates the bid price of the corresponding application program among the application programs.

4. The apparatus according to claim 1, further comprising an activating unit for activating an application program, wherein the activating unit is provided correspondingly to each of the application programs among the application programs and activates the corresponding application program, when the corresponding application program is not active and the resource is allocated to the corresponding application program.

5. The apparatus according to claim 4, wherein the activating unit further receives a processing request for the activated corresponding application program, and transfers the received processing request to the activated corresponding application program.

6. The apparatus according to claim 1, wherein the bid-price calculating unit is provided as a single unit for the application programs, and calculates respective bid prices of the corresponding application programs.

7. The apparatus according to claim 6, wherein the bid-price calculating unit takes a predetermined initial value as the bid price of an inactive application program among the corresponding application programs.

8. The apparatus according to claim 6, further comprising an activating unit for activating an application program, wherein the activating unit receives a processing request for an application program to which the resource is allocated among the application programs, and activates the application program for which a process is requested by the processing request, when the application program for which a process is requested by the processing request is not activated.

9. The apparatus according to claim 6, further comprising an activating unit for activating an application program, wherein the activating unit is provided correspondingly to the bid-price calculating unit and activates an application program to which the resource is allocated, when the application program is not activated.

10. The apparatus according to claim 8, further comprising an individual bid-price calculating unit that is provided correspondingly to each of the application programs, activated when the corresponding application program is activated, and calculates the bid price of the corresponding application program.

11. The apparatus according to claim 9, further comprising an individual bid-price calculating unit that is provided correspondingly to each of the application programs, activated when the corresponding application program is activated, and calculates the bid price of the corresponding application program.

12. A computer program product having a computer readable medium including programmed instructions for determining allocation of a resource for each of a plurality of application programs to consume or supply within a predetermined unit-time based on a bidding, wherein the instructions, when executed by a computer, cause the computer to perform:

discriminating between an active application program and an inactive application program among the application programs;

calculating a bid price indicating a virtual price of the resource in the bidding to be a value at which the resource is to be preferentially allocated to the active application program rather than the inactive application program; and

allocating the resource to each of the application programs based on the bid price calculated in the calculating.
