摘要： One embodiment of the present invention sets forth a computer-implemented method for migrating a memory page from a first memory to a second memory. The method includes determining a first page size supported by the first memory. The method also includes determining a second page size supported by the second memory. The method further includes determining a use history of the memory page based on an entry in a page state directory associated with the memory page. The method also includes migrating the memory page between the first memory and the second memory based on the first page size, the second page size, and the use history.

摘要： One embodiment of the present invention includes a hash selector that facilitates performing effective hashing operations. In operation, the hash selector creates a transformation matrix that reflects specific optimization criteria. For each hash value, the hash selector generates a potential hash value and then computes the rank of a submatrix included in the transformation matrix. Based on this rank in conjunction with the optimization criteria, the hash selector either re-generates the potential hash value or accepts the potential hash value. Advantageously, the optimization criteria may be tailored to create desired correlations between input patterns and the results of performing hashing operations based on the transformation matrix. Notably, the hash selector may be configured to efficiently and reliably incrementally generate a transformation matrix that, when applied to certain strides of memory addresses, produces a more uniform distribution of accesses across caches lines than previous approaches to memory addressing.
