Job Scheduler OAR

Access control scripts (admission_rules)

OAR Administration

These scripts must be entered in the sql table called "admission_rules" or can be added using oaradmin:

oaradmin -a [rule_id] [-f file]

To edit a rule:

oaradmin -e [rule_id] [-f file]


1. Maximum walltime: passive 336 hours, interactive 2 hours.

NOTE: The following script works in oar version 2.5 
my $max_interactive_walltime = OAR::IO::sql_to_duration("2:00:00");
# 7 days = 168 hours
my $max_batch_walltime = OAR::IO::sql_to_duration("336:00:00");
foreach my $mold (@{$ref_resource_list}){
    if (defined($mold->[1])){
        if (($jobType eq "INTERACTIVE") and ($reservationField eq "None") and ($max_interactive_walltime < $mold->[1])){ 
            print("[ADMISSION RULE] Walltime too big for an INTERACTIVE job so it is set to $max_interactive_walltime.\n");
            $mold->[1] = $max_interactive_walltime;
        }elsif ($max_batch_walltime < $mold->[1]){
            print("[ADMISSION RULE] Walltime too big for a BATCH job so it is set to $max_batch_walltime.\n");
            $mold->[1] = $max_batch_walltime;
        }
    }
}
NOTE: The following script works in oar version 2.4 
update admission_rules set rule=
'my $max_interactive_walltime = iolib::sql_to_duration("2:00:00")\;
# 14 days = 336 hours
my $max_batch_walltime = iolib::sql_to_duration("336:00:00")\;
foreach my $mold (@{$ref_resource_list}){
    if (defined($mold->[1])){
        if (($jobType eq "INTERACTIVE") and ($reservationField eq "None") and ($max_interactive_walltime < $mold->[1])){
            print("[ADMISSION RULE] Walltime too big for an INTERACTIVE job so it is set to $max_interactive_walltime.\n")\;
            $mold->[1] = $max_interactive_walltime\;
        }elsif ($max_batch_walltime < $mold->[1]){
            print("[ADMISSION RULE] Walltime too big for a BATCH job so it is set to $max_batch_walltime.\n")\;
            $mold->[1] = $max_batch_walltime\;
        }
    }
}' where id=11;
NOTE: The previous script replaces the original rule 11 (in the current guane setup) That original rule is presented below:
# Set the maximum walltime
my $max_walltime = iolib::sql_to_duration("12:00:00");
if (($jobType eq "INTERACTIVE") and ($reservationField eq "None")){ 
    foreach my $mold (@{$ref_resource_list}){
        if ((defined($mold->[1])) and ($max_walltime < $mold->[1])){
            print("[ADMISSION RULE] Walltime to big for an INTERACTIVE job so it is set to $max_walltime.\n");
            $mold->[1] = $max_walltime;
        }
    }
}

2. Limit maximum jobs per user at a given time. 

my $max_total_jobs = 2;
my $nb_jobs = $dbh->do("	SELECT job_id
								FROM jobs
								WHERE
									job_user = '$user' AND
									reservation = 'None' AND
									(state = 'Waiting'
										OR state = 'Hold'
										OR state = 'toLaunch'
										OR state = 'toAckReservation'
										OR state = 'Launching'
										OR state = 'Running'
										OR state = 'Suspended'
										OR state = 'Resuming'
										OR state = 'Finishing')
								");
if ($nb_jobs >= $max_total_jobs){
	die("You cannot have more than $max_interactive_jobs interactive jobs at a time.\n");
}

3. Limit jobs to allow at least one interactive job.

To be continued.
