Abstract

Methods, systems and apparatuses for processor selection in multi-processor systems are disclosed. An example method includes, for each of a plurality of processors, retrieving a list of interrupt instances for a plurality of interrupt types; calculating an interrupt instance count value for each of the plurality of interrupt types; multiplying a corresponding weighting factor by the interrupt instance count value for each one of the plurality of interrupt types to generate a plurality of weighted interrupt values; calculating an overall weighted vector value based on the sum of the plurality of weighted interrupt values; and designating one of the plurality of processors as a selected processor based on the lowest overall weighted vector value.

First claim

What is claimed is:

1. A method to select a processor for a thread, comprising:
for each of a plurality of processors:
calculating interrupt instance count values for respective ones of a plurality of interrupt types;
calculating weighting factors for respective ones of the plurality of interrupt types, the weighting factors respectively based on a relative difference between resource consumption for respective ones of the plurality of interrupt types;
multiplying a correspon…
