Memory management system in a computer system with shared memory mappings |
摘要 |
A memory management sub-system includes code executable by a processor fir performing selecting a plurality of contexts, and selecting a sample of the separately allocable portions of an address space for each of the contexts. For each of the selected allocable portions, a corresponding portion of the host memory to which the selected allocable portion is mapped is determined, and a count corresponding to a number of separately allocable portions of any context that are commonly mapped to the corresponding portion of the host memory. For each context, a metric is computed that is a function of the counts for that context. Host memory is allocated among the contexts at least in part based on their respective metrics. |
