Hi!
numa01.sh does something like:
* numastat > /tmp/before
* starts a binary with the specified memory policy using numactl (or a
like):
numactl --interleave=all get_some_memory_with_malloc_and_write_it
* `sleep` for few seconds
* numastat > /tmp/after
* compares /tmp/before and /tmp/after to check that the numa policy
was applied the right way
But the problem is that on a host with many NUMA nodes (8) the process
of updating that numastats statistics takes some time. Even 10 seconds
may be not enough. Therefore the test fails.
Does anybody know if there is a direct or indirect way to force the
kernel to update the NUMA statistics?
Thank you.
