Computer program product for fetching from a first physical memory between an execution of a plurality of threads associated with a second physical memory

摘要

A computer program product, apparatus and associated method/processing unit are provided for utilizing a physical memory system including a first physical memory of a first physical memory class, and a second physical memory of a second physical memory class communicatively coupled to the first physical memory. In operation, one or more pages are fetched from the first physical memory using a time between an execution of a plurality of threads associated with the second physical memory.

主权项

1. A computer program product embodied on a non-transitory computer readable medium, comprising:
code for working in conjunction with a processing unit to cooperate with a memory system including:
a first physical memory of a first physical memory class; anda second physical memory of a second physical memory class, the second physical memory communicatively coupled to the first physical memory; code for causing transmission, over a standard bus, of a special command including special data, for causing particular data in the first physical memory of the first physical memory class to be written to the second physical memory of the second physical memory class, code for allowing a check of a status to determine if the particular data is ready, and code for causing transmission of a read command in connection with a same at least one read operation associated with the special command, wherein the computer program product is operable in conjunction with the processing unit for causing at least a portion of the particular data to be written to the second physical memory of the second physical memory class between an execution of a plurality of threads.
