Dynamic resource management system and method for multiprocessor systems

A system for dynamically managing a computer system having a plurality of processors, comprising:

• at least one processor;
• a computer memory device in communication with said at least one processor bearing computer computer-executable instructions capable of identifying a first set of computer-readable instructions;
• a computer memory device in communication with said at least one processor bearing computer computer-executable instructions capable of identifying a second set of computer-readable instructions wherein said first set of computer-readable instructions and said second set of computer-readable instructions comprise an application group;
• a computer memory device in communication with said at least one processor bearing computer-executable instructions capable of assigning the application group to at least one of said plurality of processors using an affinity mask;
• and
• a computer memory device in communication with said at least one processor bearing computer-executable instructions capable of automatically adjusting the number of processors assigned to said application group by adding to the affinity mask based on processor usage in the system, and removing the processor from the affinity mask based on processor usage in the system and in a reverse order that the processor is added to the affinity mask, the adjustments being made after at least the first set of computer readable instructions are elevated in priority class.

An article of manufacture comprising:

• a processor readable medium bearing computer-readable instructions of dynamically managing a computer system having a plurality of processors, comprising:
• instructions for identifying a first set of computer-readable instructions;
• instructions for identifying a second set of computer-readable instructions wherein said first set of computer-readable instructions and said second set of computer-readable instructions comprise an application group;
• instructions for assigning the application group to at least one of said plurality of processors using an affinity mask;
• and
• instructions for automatically adjusting the number of processors assigned to said application group by adding to the affinity mask based on processor usage in the system, and removing the processor from the affinity mask based on processor usage in the system and in a reverse order that the processor is added to the affinity mask, the adjustments being made after at least the first set of computer readable instructions are elevated in priority class.
