# Check for Prime Time Enforcement.  Sites with a mixed user base can use 
# this option to enforce separate scheduling policies at different times
# during the day.  Refer to the INTERACTIVE_QUEUES description for the current
# prime-time scheduling policy.  If ENFORCE_PRIME_TIME is set to "0", the 
# non-prime-time scheduling policy (as described in BATCH_QUEUES) will be used 
# for the entire 24 hour period.
#
# If enforcement is needed at some future time, it may be specified on the
# configuration line instead of "True".  The syntax of the date string is
# MM/DD/YYYY@HH:MM:SS (due to limitations of the parsing engine).  For 
# instance, to start enforcing primetime on January 1, 2000 at 8:00AM, use
# the following configuration line:
#
#	ENFORCE_PRIME_TIME	01/01/2000@08:00:00
#
ENFORCE_PRIME_TIME		False

# Prime-time is defined as a time period each working day (Mon-Fri)
# from PRIME_TIME_START through PRIME_TIME_END.  Times are in 24
# hour format (i.e. 9:00AM is 9:00:00, 5:00PM is 17:00:00) with hours, 
# minutes, and seconds.  Sites can use the prime-time scheduling policy for 
# the entire 24 hour period by setting PRIME_TIME_START and PRIME_TIME_END 
# back-to-back.  The portion of a job that fits within primetime must be
# no longer than PRIME_TIME_WALLT_LIMIT (represented in HH:MM:SS).
#
PRIME_TIME_START		???
PRIME_TIME_END			???
PRIME_TIME_WALLT_LIMIT		???

# Some systems may want a split time limit for small and large jobs.  If this
# is required, the split will be made at PRIME_TIME_SMALL_NODE_LIMIT nodes,
# with jobs less than that value being allowed PRIME_TIME_SMALL_WALLT_LIMIT
# time values, and larger jobs getting PRIME_TIME_WALLT_LIMIT.
# For instance, for 8 nodes or more, give them PRIME_TIME_WALLT_LIMIT, but
# if smaller, give them 5 minutes:
#PRIME_TIME_SMALL_NODE_LIMIT	8
#PRIME_TIME_SMALL_WALLT_LIMIT	0:05:00

# Additionally, some sites may want a non-primetime walltime limit that is
# different for different sized jobs.  If so, set the SMALL_JOB_MAX option
# to that size, and choose time limits.  For instance, for more than 8 nodes,
# give them 4 hours outside of primetime.  Otherwise, give 2 hours.
#
# SMALL_JOB_MAX			8
# WALLT_LIMIT_LARGE_JOB		4:00:00
# WALLT_LIMIT_SMALL_JOB		2:00:00

# Interactive jobs that have been queued for (INTERACTIVE_LONG_WAIT + the
# requested walltime) will be considered "long outstanding".  This is based
# on the theory that there is a human on the other end of the 'qsub -I', but
# batch jobs have a looser idea of "long outstanding".
#
INTERACTIVE_LONG_WAIT		0:30:00

# Jobs that have been waiting on the submit queue for a long period of time
# should be given higher priority, in order to prevent starvation.  If the
# scheduler should go out of its way to run a long-waiting job (even to the
# extreme of draining the system for it), set the MAX_QUEUED_TIME to the
# amount of time that is "too long".  24 to 48 hours is usually good.
#
MAX_QUEUED_TIME			24:00:00

# Check for Dedicated/Preventative Maintenance Time Enforcement.  This option
# requires the NAS 'pbsdedtime' command which in turn depends on the NAS 
# 'schedule' program.
#
# If enforcement is needed at some future time, it may be specified on the
# configuration line instead of "True".  The syntax of the date string is
# MM/DD/YYYY@HH:MM:SS (due to limitations of the parsing engine).  For 
# instance, to start enforcing dedicated time on January 1, 2000 at 8:00AM, 
# use the following configuration line:
#
#	ENFORCE_DEDICATED_TIME	01/01/2000@08:00:00
#
ENFORCE_DEDICATED_TIME		False

# Command used to check for upcoming dedicated/preventative maintenance time. 
# Supply the absolute path to NAS 'pbsdedtime' or a similar command.  This
# command will be executed with the short name of an execution host as its
# only argument.  For instance, "/usr/local/pbs/sbin/pbsdedtime hopper".
#
DEDICATED_TIME_COMMAND		???

# To minimize the impact on the schedule server, as well as reduce average
# run time, the scheduler caches the responses for upcominig outages.
# The last response from the DEDICATED_TIME_COMMAND will be cached for this 
# many seconds (300 is recommended).  
# The outages cache is invalidated upon catching a SIGHUP.
#
DEDICATED_TIME_CACHE_SECS	300

# If your machines are running in a cluster configuration, you can specify a
# "logical system name" for the cluster as a whole.  DEDICATED_TIME_COMMAND
# must be able to return valid information for this "hostname".  Any dedicated
# times returned for SYSTEM_NAME will override the dedicated time (or the lack
# thereof) for any host in the cluster.  Overlaps will be resolved correctly,
# with the system dedicated times getting priority.
# This option may be useful if your schedule dedicated time for individual
# hosts.  Point SYSTEM_NAME to the front-end to prevent scheduling jobs when
# the front-end is in dedicated time (otherwise, dedicated time is checked for
# the back-ends only).
#SYSTEM_NAME			???

# If SORT_BY_PAST_USAGE is non-zero, the list of jobs will be permuted to
# bring the least active users' jobs to the front of the list.  This may
# provide some sense of fairness, but be warned that it may cause the choice
# of jobs to be fairly inexplicable from the outside.  The "past usage" is
# decayed daily by one of two values, DECAY_FACTOR or OA_DECAY_FACTOR.  The
# OA_DECAY_FACTOR is used if the ENFORCE_ALLOCATION is on, and the user is
# over their allocations.  Decays must be <= 1.0, with lower numbers 
# indicating quicker decay.
#
SORT_BY_PAST_USAGE		True
#DECAY_FACTOR			0.75
#OA_DECAY_FACTOR		0.95

# Check for Allocation Enforcement.  This option depends on the NAS ACCT++ 
# program and a Data Loading Client.  
#
# If enforcement is needed at some future time, it may be specified on the
# configuration line instead of "True".  The syntax of the date string is
# MM/DD/YYYY@HH:MM:SS (due to limitations of the parsing engine).  For 
# instance, to start enforcing allocations on January 1, 2000 at 8:00AM, 
# use the following configuration line:
#
#	ENFORCE_ALLOCATION	01/01/2000@08:00:00
#
ENFORCE_ALLOCATION		False

# Absolute path to the $(PBS_SERVER_HOME)/pbs_acctdir directory which contains
# the accounting year-to-date (YTD) and allocation files.
#
SCHED_ACCT_DIR			???

# Choose an action to take upon scheduler startup.  The default is to do no
# special processing (NONE).  In some instances, for instance with check-
# pointing, a job can end up queued in one of the batch queues, since it was 
# running before but was stopped by PBS.  If the argument is RESUBMIT, these 
# jobs will be moved back to the first submit queue, and scheduled as if
# they had just arrived.  If the argument is RERUN, the scheduler will have
# PBS run any jobs found enqueued on the execution queues.  This may cause
# the machine to get somewhat confused, as no limits checking is done (the
# assumption being that they were checked when they were enqueued).
#
SCHED_RESTART_ACTION		RESUBMIT

# Use heuristics to attempt to reduce the problem of queue fragmentation.
# If AVOID_FRAGMENTATION is set, jobs that will cause or prolong queue
# fragmentation will not be run.  Once the queue becomes fragmented, this
# will clear the small jobs out of the queue by favoring larger jobs.
# This is probably not very useful in most situations, but might help if
# your site has lots of very small jobs and several queues.
#
AVOID_FRAGMENTATION		False

# In order to guarantee that large jobs will be able to run at night, set
# the NONPRIME_DRAIN_SYS option to True.  This will cause a hard barrier to
# be set at the time between prime-time and non-prime-time, so the system
# will drain down to idle just before non-prime-time begins.
#
NONPRIME_DRAIN_SYS		False

# For debugging and evaluation purposes, it might be useful to have a file
# listing the "pre-scheduling" sorted list of jobs (including any special
# attributes) updated at each run.  If SORTED_JOB_DUMPFILE is specified,
# the sorted list of jobs will be dumped into it.  If special permissions,
# etc, are needed, create it with those permissions before starting the
# scheduler.  If the file does not exist, it will be created with the default
# permissions and owner/group.
#
# A good place for this file might be $(PBS_HOME)/sched_priv/sortedjobs

#SORTED_JOB_DUMPFILE		???
