Abstract

A method and an apparatus for identifying a processing configuration, identifying a piece of application software, and using processor affinity information from an affinity database to determine which processor(s) or duplicated component(s) of a processor to use in executing the piece of application software.

Claims

1. A method comprising:

identifying a processing configuration of a computer system;

starting the execution of a piece of application software;

identifying the piece of application software;

searching for an entry corresponding to the piece of application software in an affinity database; and

using information from the entry corresponding to the piece of application software to select at least one processor of the computer system for executing the piece of application software.

2. The method of claim 1, wherein starting the execution of a piece of application software further comprises using a user interface provided by software that does the searching for an entry in the affinity database.

3. The method of claim 1, wherein the identifying the piece of application software occurs after starting the execution of the piece of application software, and further comprises awaiting the provision of identifying information by the piece of application software as the application software is executed.

4. The method of claim 1, wherein using the information from the entry corresponding to the piece of application software to select at least one processor further comprises using the information from the entry corresponding to the piece of application software to select at least one of a plurality of duplicated components within the at least one processor for executing the application software.

5. A method comprising providing a component of a computer system together with a piece of machine-accessible medium comprised of instructions that, if executed by a processor of a computer system comprised of the component, will cause the processor of the computer system to:

identify a processing configuration of the computer system;

identify a piece of application software;

search for an entry corresponding to the piece of application software in an affinity database; and

use information from the entry corresponding to the piece of application software to select at least one processor of the computer system for executing the application software.

6. The method of claim 5, wherein the machine-accessible medium is further comprised of the affinity database.

7. The method of claim 5, further comprising providing at least one update to the instructions comprising the machine-accessible medium.

8. The method of claim 5, further comprising providing at least one update to the affinity database.

9. A machine-accessible medium comprised of instructions that, if executed by a machine, will cause the machine to:

identify a processing configuration of the machine;

identify a piece of application software;

search for an entry corresponding to the piece of application software in an affinity database; and

use information from the entry corresponding to the piece of application software to select at least one processor of the machine for executing the application software.

10. The machine-accessible medium of claim 9, wherein the machine is further caused to provide a user interface to allow a user of the machine to start the execution of the piece of application software.

11. The machine-accessible medium of claim 9, wherein the machine is further caused to identify the piece of application software by awaiting the provision of identifying information by the application software after execution of the application software has begun.

12. The machine-accessible medium of claim 9, wherein the machine is further caused to use information from the entry corresponding to the piece of application software to select at least one of a plurality of duplicated components within the at least one processor of the machine for executing the application software.
