The manpage for "sge_conf" will tell you about the $max_jobs and  
$max_u_jobs settings you can apply.

These are sort of legacy "big stick" approaches to job/user throttling  
and limits.

The more accepted/modern way these days is via Resource Quotas - more  
powerful tools and a far more flexible set of things you can select  
and apply limits to.

None of the methods though can distinguish among jobs in a particular  
state ("qw") though from what I can recall.
