The present disclosure is directed to techniques for migrating data between heterogeneous memories in a computing system. More specifically, the techniques involve migrating data between a memory having better access characteristics (e.g., lower latency but greater capacity) and a memory having worse access characteristics (e.g., higher latency but lower capacity). Migrations occur with a variable migration granularity. A migration granularity specifies a number of memory pages, having virtual addresses that are contiguous in virtual address space, that are migrated in a single migration operation. A history-based technique that adjusts migration granularity based on the history of memory utilization by an application is provided. A profiling-based technique that adjusts migration granularity based on a profiling operation is also provided.
A method for migrating data between a first memory and a second memory, the method comprising:
A non-transitory computer-readable medium storing instructions that, when executed by a processor, cause the processor to migrate data between a first memory and a second memory by:
A computing system, comprising:
