摘要

Optimizing computer hardware usage in a computing system that includes a plurality of populated central processing unit (‘CPU’) sockets, including: determining, by a socket configuration module, a number of CPUs to be utilized during operation of the computing system; determining, by the socket configuration module, performance characteristics associated with each available CPU, the performance characteristics associated with each available CPU including information describing computing devices such as memory devices, input/output (‘I/O) devices, and other downstream devices that are coupled to one or more of the available CPUs; and selecting, by the socket configuration module in dependence upon the performance characteristics associated with each available CPU and a predetermined performance policy, a target CPU to utilize as a boot CPU.

1. An apparatus comprising a computer processor and a computer memory operatively coupled to the computer processor, the computer memory having disposed within it computer program instructions that, when executed by the computer processor, cause the apparatus to carry out the steps of:
determining, by a socket configuration module, a number of central processing units (“CPUs”) of a computing system to be utilized during operation of the computing system; determining, by the socket configuration module, performance characteristics associated with computing devices that are off-chip from the number of CPUs and that are coupled to one or more of the number of CPUs; and selecting, by the socket configuration module in dependence upon the performance characteristics associated with the computing devices that are off-chip from the number of CPUs and a predetermined performance policy, a target CPU of the number of CPUs to utilize as a boot CPU.
