.IP resources_default 8
The list of default resource values which are set as limits for a job 
residing in this queue and for which the job did not specify a limit.  
If not explicitly set, the default limit for a job is determined by
the first of the following attributes which is set: server's 
.I resources_default,
queue's 
.I resources_max, 
server's 
.I resources_max.  
If none of these is set, the job gets unlimited resource usage.

Format for removing from a limit specification:
.RS 11

o:PBS_ALL         Overall limit
.br
u:PBS_GENERIC     Generic users
.br
u:<username>      A specific user
.br
g:PBS_GENERIC     Generic groups

p:PBS_GENERIC     Generic projects
.br

.RE
.IP
The 
.I limit specification 
can contain spaces anywhere except after the colon
(":").
.br
If there are comma-separated 
.I limit specifications, 
the entire string must be enclosed in double quotes.
.br
A username, groupname, or project name containing spaces must be
enclosed in quotes.
.br
If a username, groupname, or project name is quoted using double
quotes, and the entire string requires quotes, the outer enclosing
quotes must be single quotes.  Similarly, if the inner quotes are
single quotes, the outer quotes must be double quotes.
.br
.I PBS_ALL 
is a keyword which indicates that this limit applies to the usage total.
.br
.I PBS_GENERIC 
is a keyword which indicates that this limit applies to
generic users, groups, or projects.
.br
When removing a limit, the 
.I limit value 
does not need to be specified.
.br

For example, to set the 
.I max_queued 
limit on QueueA to 5 for total usage, and to limit user bill to 3:
.RS 11
s q QueueA max_queued = "[o:PBS_ALL=5], [u:bill =3]"
.RE
.IP

Examples of setting, adding, and removing: 
.br
.RS 11
set server max_run="[u:PBS_GENERIC=2], [g:group1=10], [o:PBS_ALL = 100]"
.br
set server max_run+="[u:user1=3], [g:PBS_GENERIC=8]"
.br
set server max_run-="[u:user2], [g:group3]"
.br
set server max_run_res.ncpus="[u:PBS_GENERIC=2], [g:group1=8], [o:PBS_ALL = 64]"

.SH Incompatible Limit Attributes
The old and new limit attributes are incompatible.  
If any of one kind is set, none of the other kind can be set.
All of one kind must be unset in order to set any of the other kind.
