    Abstract: A method of managing data during execution of an application for use in a system that includes a host memory, a near memory, and a near device associated with the near memory. The application uses a working set of data that is distributed between the far memory and the near memory. The method includes counting a number of times that the near device accesses a unit of the working set of data from the far memory, determining whether the number of times exceeds a dynamically changing access counter threshold, wherein the dynamically changing access counter threshold is calculated dynamically based on a static threshold that is set for the system, and responsive to determining that the number of times exceeds the dynamically changing access counter threshold, migrating the unit of data from the far memory to the near memory.
