* NAME
|
|
* move_pages02.c
|
|
*
|
|
* DESCRIPTION
|
|
* Test movement of pages mapped by a process.
|
|
*
|
|
* ALGORITHM
|
|
* 1. Allocate pages in NUMA node A.
|
|
* 2. Use move_pages() to move the pages to NUMA node B.
|
|
* 3. Retrieve the NUMA nodes of the moved pages.
|
|
* 4. Check if all pages are in node B.
|
|
*
|
|
* USAGE: <for command-line>
|
|
* move_pages02 [-c n] [-i n] [-I x] [-P x] [-t]
|
|
* where, -c n : Run n copies concurrently.
|
|
* -i n : Execute test n times.
|
|
* -I x : Execute test for x seconds.
|
|
* -P x : Pause for x seconds between iterations.
|
|
* -t : Turn on syscall timing.
|
|
*
|
|
* History
|
|
* 05/2008 Vijay Kumar
|
|
* Initial Version.
