Abstract
A method and system for binding a preferred CPU to a virtual partition of a computer is disclosed. In one embodiment, a preferred CPU for a virtual partition of a computer is determined upon a receipt of a request to assign a CPU to the virtual partition. Then, the preferred CPU is assigned to the virtual partition when the preferred CPU is available for assignment. Further, the preferred CPU is retained in the virtual partition when the virtual partition is rebooted.
Claims11
A method comprising:
- determining a first preferred CPU for a virtual partition on a computer upon a receipt of a first request to assign a CPU to the virtual partition, wherein the first preferred CPU is automatically determined based on operational parameters of the computer;
- assigning the first preferred CPU to the virtual partition when the first preferred CPU is available for assignment;
- in response to a second request to assign a CPU to the virtual partition, assigning a non-preferred CPU of plural available non-preferred CPUs to the virtual partition;
- while the first preferred CPU and the non-preferred CPU are assigned to the virtual partition, storing information in a virtual partition database to indicate that said first preferred CPU is a preferred CPU for the virtual partition and that said non-preferred CPU is a non-preferred CPU for the virtual partition;
- and
- upon reboot of the virtual partition and based on the information in the virtual partition database, preferentially retaining the first preferred CPU in the virtual partition and randomly assigning a specified number of the available non-preferred CPUs to the virtual partition.
