NAME¶
calendar_conf - Sun Grid Engine calendar configuration file format
DESCRIPTION¶
calendar_conf reflects the format of the Sun Grid Engine calendar
configuration. The definition of calendars is used to specify "on
duty" and "off duty" time periods for Sun 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, Sun Grid Engine allows backslashes (\) be used to escape newline
(\newline) characters. The backslash and the newline are replaced with a space
(" ") character before any interpretation.
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
and 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 a 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 compliance 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 the entire
week from 12.00-18.00 with the exception of Tuesday between 13.00-17.00 where
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 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, no settings on the year basis
(keyword "NONE").
calendar_name weekend_s
year NONE
week sat-sun=suspended
