Depending on the grid provider being used, you can define queues in lsb.queues (LSF) or in the SAS Grid Manager web interface under configuration -> queues).
Both support pointing queues to a subset of all grid nodes as execution hosts, and specifying a CPU time limit if that's what you mean by CPU limit.
lsb.queues (see HOSTS and CPULIMIT sections)
