The total swap on the server is divided amongst the cnodes in a shared
cluster; no c-node has a limit short of the total; thus all the space
is available for any given cnode.  

[Unless you have local swap; then each node can swap to its local
disk, and to a remote disk as well, i think, which makes things much 
more complex for your purposes...]

as already suggested, monitor is your friend when trying to do this.

This munges the information held on the server about what swap is
being used by each cnode.  

Hope this is useful
