Hi, could someone please explain the behaviour of a nodestring "+0-1" or similar for numa_parse_nodestring? According to the manual, "a leading + can be used to indicate that the node numbers in the list are relative to the task's cpuset". What I expected and want to achieve is, that if a process was started on node 3, I will get a node mask of 3,4. What I get (on a kernel 2.6.32) is always 0,1 independently of the node the process was started (either by chance or by assigning a specific node with numactl). Background: I want to limit a multithreaded process to a subset of the available nodes, but want to include the node it currently runs on, because I assume that the memory (stack/heap) already in use by the process is mainly on this node, so it makes sense to include this node. I know I could simply start the process with numactl, but I want to implement a useful default behavior and for the kind or process this is neither achieved by limiting to one node nor to all nodes. Thanks in advance for any help.
