Hello,
How can I move already allocated and accessed memory to a different
node? I know how to do it, if the memory pages are not faulted, but in
my code I want to transfer enough megabytes of data to an other node
for processing them locally.
Thanks
Christos

This is actually for migrating all the allocations of a node. If I
want to migrate only some pages and not all?
This is actually my problem.

That's move_pages() in tree, or some out of tree alternatives.
