CALENDAR_CONF(5) Grid Engine File Formats CALENDAR_CONF(5)

NAME

calendar_conf - Grid Engine calendar configuration file format

DESCRIPTION

calendar_conf defines the format of the Grid Engine calendar configuration. The definition of calendars is used to specify "on duty" and "off duty" time periods for Grid Engine queues on a time of day, day of week, or day of year basis. Various calendars can be implemented, and the appropriate calendar definition for a certain class of jobs can be attached to a queue.
calendar_conf entries can be added, modified and displayed with the -Acal, -acal, -Mcal, -mcal, -scal and -scall options to or with the calendar configuration dialog of the graphical user interface
Note that jobs may be dispatched incorrectly into calendar windows which are too short unless resource reservation is turned on by setting max_reservation in
Note, Grid Engine allows backslashes (\) to escape newline characters. The backslash and the newline are replaced with a space (" ") character before any interpretation.

FORMAT

A configuration comprises three lines of this form, whose contents are described in the following sections:
 
	 calendar_name  calendar_name
	 yesr  year
	 day  day

calendar_name

The name of the calendar to be used when attaching it to queues, or when administering the calendar definition. See calendar_name in for a precise definition of valid calendar names.

year

The queue status definition on a day of the year basis. This field generally will specify on which days of a year (and optionally at which times on those days) a queue, to which the calendar is attached, will change to a certain state. The syntax of the year field is defined as follows:
 
year :=
	 NONE
	|  year_day_range_list=daytime_range_list[=state]
	|  year_day_range_list=[daytime_range_list=]state
	|  state
 
Where
NONE means no definition is made on the year basis;
If a definition is made on the year basis, at least one of year_day_range_list, daytime_range_list and state always have to be present;
All day long is assumed if daytime_range_list is omitted;
Switching the queue to "off" (i.e. disabling it) is assumed if state is omitted;
The queue is assumed to be enabled for days neither referenced implicitly (by omitting the year_day_range_list) nor explicitly.
The syntactical components are defined as follows:
 
	 year_day_range_list := 	{yearday-yearday | yearday},...
	 daytime_range_list := 	hour[:minute][:second]-hour[:minute][:second],...
	 state := 	on | off | suspended
	 year_day :=	month_day.month.year
	month_day :=	1 | 2 | ... | 31
	month :=	jan | feb | ... | dec | 1 | 2 | ... | 12
	year :=	1970 | 1971 | ... | 2037

week

The queue status definition on a day of the week basis. This field generally will specify on which days of the week (and optionally at which times on those days) a queue to which the calendar is attached will change to a certain state. The syntax of the week field is defined as follows:
 
week:=
	 NONE 
	|  week_day_range_list[=daytime_range_list][=state]
	| [ week_day_range_list=]daytime_range_list[=state]
	| [ week_day_range_list=][daytime_range_list=]state ...
 
where
NONE means, no definition is made on the week basis;
If a definition is made on the week basis, at least one of week_day_range_list, daytime_range_list and state always have to be present;
Every day in the week is assumed if week_day_range_list is omitted;
Syntax and semantics of daytime_range_list and state are identical to the definition given for the year field above;
The queue is assumed to be enabled for days neither referenced implicitly (by omitting the week_day_range_list) nor explicitly.
and where week_day_range_list is defined as
 
	 week_day_range_list := 	{weekday-weekday | weekday},...
	 week_day := 	mon | tue | wed | thu | fri | sat | sun
 
With week_day ranges the week_day identifiers must be different.

SEMANTICS

Successive entries to the year and week fields (separated by blanks) are combined in accordance with the following rule:
off areas are overridden by overlapping on and suspended areas and suspended areas are overridden by on areas.
Hence an entry of the form
 
	week 	12-18 tue=13-17=on
 
means that queues referencing the corresponding calendar are disabled for the entire week from 12.00-18.00, with the exception of Tuesday between 13.00-17.00, when the queues are available.
 
Area overriding occurs only within a year/week basis. If a year entry exists for a day, then only the year calendar is taken into account, and no area overriding is done with a possibly conflicting week area.
 
The second time specification in a daytime_range_list may be before the first one and treated as expected. Thus an entry of the form
 
	year 	12.03.2004=12-11=off 
    
 
causes the queue(s) be disabled on 12.03.2004 from 00:00:00 - 10:59:59 and 12:00:00 - 23:59:59.

EXAMPLES

(The following examples are contained in the directory $SGE_ROOT/util/resources/calendars.)
Night, weekend and public holiday calendar:
 
On public holidays "night" queues are explicitly enabled. On working days queues are disabled between 6.00 and 20.00. Saturday and Sunday are implicitly handled as enabled times:
 
	calendar_name 	night
	year 	1.1.1999,6.1.1999,28.3.1999,30.3.1999-
	31.3.1999,18.5.1999-19.5.1999,3.10.1999,25.12.1999,26
	.12.1999=on
	week 	mon-fri=6-20
    
 
Day calendar:
 
On public holidays "day"-queues are disabled. On working days such queues are closed during the night between 20.00 and 6.00, i.e. the queues are also closed on Monday from 0.00 to 6.00 and on Friday from 20.00 to 24.00. On Saturday and Sunday the queues are disabled.
 
	calendar_name 	day
	year 	1.1.1999,6.1.1999,28.3.1999,30.3.1999-
	31.3.1999,18.5.1999-19.5.1999,3.10.1999,25.12.1999,26
	.12.1999
	week 	mon-fri=20-6 sat-sun
    
 
Night, weekend and public holiday calendar with suspension:
 
Essentially the same scenario as the first example but queues are suspended instead of switching them "off".
 
	calendar_name 	night_s
	year 	1.1.1999,6.1.1999,28.3.1999,30.3.1999-
	31.3.1999,18.5.1999-19.5.1999,3.10.1999,25.12.1999,26
	.12.1999=on
	week 	mon-fri=6-20=suspended
    
 
Day calendar with suspension:
 
Essentially the same scenario as the second example, but queues are suspended instead of switching them "off".
 
	calendar_name 	day_s
	year 	1.1.1999,6.1.1999,28.3.1999,30.3.1999-
	31.3.1999,18.5.1999-19.5.1999,3.10.1999,25.12.1999,26
	.12.1999=suspended
	week 	mon-fri=20-6=suspended sat-sun=suspended
    
 
Weekend calendar with suspension, ignoring public holidays:
 
Settings are only done on the week basis, with no settings on the year basis (keyword "NONE").
 
	calendar_name 	weekend_s
	year 	NONE
	week 	sat-sun=suspended
