Lines Matching full:access
17 monitor and visualize access patterns on the physical address space of a system
23 Let's start by capturing the access pattern snapshot on the physical address
27 the capturing of the snapshot, to show a meaningful time-wise access patterns.
35 Then, list the DAMON-found regions of different access patterns, sorted by the
36 "access temperature". "Access temperature" is a metric representing the
37 access-hotness of a region. It is calculated as a weighted sum of the access
38 frequency and the age of the region. If the access frequency is 0 %, the
