Hi,
For some strange reason global tags (such as “cores”) don’t support the
“nodeset” syntax. For “cores” the only supported attribute is “node”, and then
you’re only allowed to use #ANY or a single specific node name (with optional
“!" NOT operand), or a JSON array containing node names to indicate the IN
operand.
The Ref Guide indeed is not very clear on that…
