  * `TORQUE_TMPDIR` : normally defined to refer to the working area created by Torque for each job, on a local filesystem. Define as `null` if you don't want job current directory to be redefined to this directory.
 
- * `WN_ATTRS` : this variable is a nlist with one entry per worker node (key is the escaped node fullname). Each value is a set of PBS/Torque attribute to set on the node. Value value are any `key=value` supported by `qmgr set server` command. One useful value is `status=offline` to cause a specific node to drain or `status=online` to reenable the node. Just suppressing `status=offline` is not enough to reenable the node. One specific entry in `WN_ATTRS` is `DEFAULT` : this entry is applied to any node that doesn't have a specific entry.

Values are any `key=value` supported by `qmgr set server` command. One useful value is `state=offline` to cause a specific node to drain or `state=online` to reenable the node. Just suppressing `state=offline` is not enough to reenable the node. One specific entry in `WN_ATTRS` is `DEFAULT` : this entry is applied to any node that doesn't have a specific entry. If you want to avoïd re-enabling a node explicitely, you can have the `DEFAULT` entry be defined with the `state=free` arguments. For instance, you could define :
+{{{
+variable WN_ATTRS ?= nlist(
+    "DEFAULT", nlist("state","free"),
+    "mynode.mydomain.com", nlist("state","offline")
+);

  * `WN_CPUS_DEF` : default number of CPU per worker node.
