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 qconf(1) or
with the calendar configuration dialog of the graphical user interface
qmon(1).
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 sched_conf(5).
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
sge_types(5) 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
o NONE means no definition is made on the year basis;
o 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;
o All day long is assumed if daytime_range_list is omitted;
o Switching the queue to "off" (i.e. disabling it) is assumed if state
is omitted;
o 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
o NONE means, no definition is made on the week basis;
o 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;
o Every day in the week is assumed if week_day_range_list is omitted;
o Syntax and semantics of daytime_range_list and state are identical
to the definition given for the year field above;
o 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:
o 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.
o 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.
o 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.)
o 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
o 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
o 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
o 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
o 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
