The queues are independent of each other.
If you want to limit the number of jobs per node, you can use another
Resource Quota:
{
name maxslots
description Limit number of slots to number of CPUs
enabled TRUE
limit hosts {@allhosts} to slots=8
}
limits each node to 8 slots. By default, Grid Engine uses one slot per
core, and one job fits in each slot.
