Abstract

A computer application program executing on a computer, such as a portable computer, is selected for termination by first identifying computer application programs executing on the computer. A priority value is assigned to each of the identified computer applications. The priority value is based on multiple characteristics of the identified computer application programs. The computer application program with the smallest priority value is automatically terminated. If the computer application program with the smallest priority value is in a modal state in which it waits for a response from a user, then a default response is provided to the application prior to terminating the computer application program. The characteristics associated with the computer application programs may include average launch times, average memory usages, a class or type of application, frequencies of usage, and an amount of data stored on the computer by the computer application program.

Claims

1. A system, comprising:

one or more processors;

a memory that includes a plurality of computer-executable logics, the plurality of computer-executable logics comprising;

a first logic for determining a candidate application of currently executing applications for termination based on comparing priority values of the currently executing applications, the priority value of each currently executing application being calculated based on application parameter values that are stored in corresponding named parameters defined by an operating system, the application parameter values include;

a class parameter value that indicates a corresponding currently executing application is one of a plurality of application types, wherein the class parameter value is highest for a core application type of the plurality of application types, and

an average memory usage parameter value that represents typical memory usage of the corresponding currently executing application; and

a second logic for terminating the candidate application.

2. The system as recited in claim 1, wherein when the class parameter value is a first pre-defined value, then the corresponding currently executing application comprises a personal information manager, when the class parameter value is a second pre-defined value, then the corresponding currently executing application comprises a game, and when the class parameter value is a third predetermine value, then the corresponding currently executing application comprises a personal utility.

3. The system as recited in claim 1, wherein the core application is an application required to execute other applications or an application most frequently executed of the currently executing applications.

4. A system, comprising:

one or more processors;

a memory that includes a plurality of computer-executable logics, the plurality of computer-executable logics comprising;

a first logic for determining a candidate application of currently executing applications for termination based on comparing priority values of the currently executing applications, the priority value of each currently executing application being calculated based on application parameter values that are stored in corresponding named parameters defined by an operating system, the application parameter values include;

a class parameter value that indicates a corresponding currently executing application is one of a plurality of application types, the class parameter value being highest for a core application type of the plurality of application types, and wherein a core application is an application required for the execution of another application; and

an average memory usage parameter value that represents typical memory usage of the corresponding currently executing application; and

a second logic for terminating the candidate application.

5. The system as recited in claim 4, wherein when the class parameter value is a first pre-defined value, then the corresponding currently executing application comprises a personal information manager, when the class parameter value is a second pre-defined value, then the corresponding currently executing application comprises a game, and when the class parameter value is a third pre-defined value, then the corresponding currently executing application comprises a personal utility.

6. A system, comprising:

one or more processors;

a memory that includes a plurality of computer-executable logics, the plurality of computer-executable logics comprising;

a first logic for determining a candidate application of currently executing applications for termination based on comparing priority values of the currently executing applications, the priority value of each currently executing application being calculated based on application parameter values that are stored in corresponding named parameters defined by an operating system, the application parameter values include;

a class parameter value that indicates a corresponding currently executing application is one of a plurality of application types, wherein when the class parameter value is a first pre-defined value, then the corresponding currently executing application comprises a personal information manager, when the class parameter value is a second pre-defined value, then the corresponding currently executing application comprises a game, and when the class parameter value is a third pre-defined value, then the corresponding currently executing application comprises a personal utility, and

an average memory usage parameter value that represents typical memory usage of the corresponding currently executing application; and

a second logic for terminating the candidate application, wherein the application parameter values are stored in corresponding named parameters that are defined by an operating system.

7. The system as recited in claim 6, wherein the class parameter value is highest for a core application type of the plurality of application types.

8. The system as recited in claim 7, wherein the core application is an application required to execute other applications or an application most frequently executed of the currently executing applications.
