| 25 | * NAME |
| 26 | * move_pages01.c |
| 27 | * |
| 28 | * DESCRIPTION |
| 29 | * Test retrieval of NUMA node |
| 30 | * |
| 31 | * ALGORITHM |
| 32 | * 1. Allocate pages in NUMA nodes A and B. |
| 33 | * 2. Use move_pages() to retrieve the NUMA node of the pages. |
| 34 | * 3. Check if the NUMA nodes reported are correct. |
| 35 | * |
| 36 | * USAGE: <for command-line> |
| 37 | * move_pages01 [-c n] [-i n] [-I x] [-P x] [-t] |
| 38 | * where, -c n : Run n copies concurrently. |
| 39 | * -i n : Execute test n times. |
| 40 | * -I x : Execute test for x seconds. |
| 41 | * -P x : Pause for x seconds between iterations. |
| 42 | * -t : Turn on syscall timing. |
| 43 | * |
| 44 | * History |
| 45 | * 05/2008 Vijay Kumar |
| 46 | * Initial Version. |
