H A Dsched-debug.rst24 memory node local to where the task is running. Every "scan delay" the task
25 scans the next "scan size" number of pages in its address space. When the
28 In combination, the "scan delay" and "scan size" determine the scan rate.
29 When "scan delay" decreases, the scan rate increases. The scan delay and
30 hence the scan rate of every task is adaptive and depends on historical
31 behaviour. If pages are properly placed then the scan delay increases,
32 otherwise the scan delay decreases. The "scan size" is not adaptive but
33 the higher the "scan size", the higher the scan rate.
35 Higher scan rates incur higher system overhead as page faults must be
36 trapped and potentially data must be migrated. However, the higher the scan
