NAME

sge_types - Grid Engine type descriptions

DESCRIPTION

The Grid Engine user interface consists of several programs and files. Some command-line switches and several file attributes are types. The syntax for these types is explained in this page.

OBJECT TYPES

These types are used for defining Grid Engine configuration:

calendar_name

A calendar name is the name of a Grid Engine calendar described in

calendar_name := object_name

ckpt_name

A "ckpt_name" is the name of a Grid Engine checkpointing interface described in

ckpt_name := object_name

complex_name

A complex name is the name of a Grid Engine resource attribute described in

complex_name := object_name

host_identifier

A host identifier can be either a host name or a host group name.

host_identifier := host_name | hostgroup_name

hostgroup_name

A host group name is the name of a Grid Engine host group described in Note, to allow host group names easily be differed from host names a "@" prefix is used.

hostgroup_name := @object_name

host_name

A host name is the official name of a host node. Host names with a domain specification such as "gridmaster.sun.com" are called fully-qualified host names, whereas host names like "gridmaster" are called short host names. Note, there are the install time parameters default_domain and ignore_fqdn (see which affect how Grid Engine deals with host names in general.

jsv_url

The jsv_url has following format:

jsv_url := jsv_client_url | jsv_server_url

jsv_server_url := [ type ':' ] [ user '@' ] path

jsv_client_url := [ type ':' ] path

type := 'script'

In the moment only the type script is allowed. This means that path is either the path to a script or to a binary application which will be used to instantiate a JSV process. The type is optional till other types are supported by Grid Engine.

Specifying a user is only allowed for server JSV's. Client JSV's will automatically be started as submit user and server JSV's as admin user if not other specified.

The path has always to be the absolute path to a binary or application.

memory_specifier

Memory specifiers are positive decimal, hexadecimal or octal integer constants which may be followed by a multiplier letter. Valid multiplier letters are k, K, m, M, g and G, where k means multiply the value by 1000, K multiply by 1024, m multiply by 1000*1000, M multiply by 1024*1024, g multiply by 1000*1000*1000 and G multiply by 1024*1024*1024. If no multiplier is present, the value is just counted in bytes.

pe_name

A "pe_name" is the name of a Grid Engine parallel environment described in

pe_name := object_name

project_name

A project name is the name of a Grid Engine project described in

project_name := object_name

queue_name

A queue name is the name of a Grid Engine queue described in

queue_name := object_name

time_specifier

A time specifier either consists of a positive decimal, hexadecimal or octal integer constant, in which case the value is interpreted to be in seconds, or is built by 3 decimal integer numbers separated by colon signs where the first number counts the hours, the second the minutes and the third the seconds. If a number would be zero it can be left out but the separating colon must remain (e.g. 1:0:1 = 1::1 means 1 hours and 1 second).

user_name

A user name can be the name of a user or of the Grid Engine user object described in

user_name := object_name

userset_name

A user set name is the name of an Grid Engine access list or department described in

userset_name := object_name

object_name

An object name is a sequence of up to 512 ASCII string characters except "\n", "\t", "\r", " ", "/", ":", "'", "\", "[", "]", "{", "}", "|", "(", ")", "@", "%", "," or the " character itself.

MATCHING TYPES

These types are used for matching Grid Engine configuration:

expression

A wildcard expression is a regular boolean expression that consists of one or more patterns joined by boolean operators. When a wildcard expression is used, the following definition applies:

 
 expression= ["!"] ["("] valExp [")"] [ AND_OR expression ]*
 valExp  = pattern | expression
 AND_OR  = "&" | "|"
 

where:

 
 "!"       not operator -- negate the following pattern or expression 
 "&"       and operator -- logically and with the following expression
 "|"       or operator -- logically or with the following expression
 "("       open bracket -- begin an inner expression.
 ")"       close bracket -- end an inner expression. 
 "pattern" see the pattern definition that's follow
 

The expression itself should be put inside quotes ('"') to ensure that clients receive the complete expression.

e.g.

 
 "(lx*|sol*)&*64*" any string beginning with either "lx" or
                   "sol" and containing "64"
 "rh_3*&!rh_3.1"   any string beginning with "rh_3", except
                   "rh_3.1"
 

pattern

When patterns are used the following definitions apply:

 
 "*"     matches any character and any number of characters 
         (between 0 and inv).
 "?"     matches any character. It cannot be no character
 "."     is the character ".". It has no other meaning
 "\"     escape character. "\\" = "\", "\*" = "*", "\?" = "?"
 "[...]" specifies an array or a range of allowed 
         characters for one character at a specific position.
         Character ranges may be specified using the a-z notation.
         The caret symbol (^) is not interpreted as a logical
         not; it is interpreted literally.
 
 For more details please see 
 
 

The pattern itself should be put inside quotes ('"') to ensure that clients receive the complete pattern.

range

The task range specifier has the form

n[-m[:s]][,n[-m[:s]], ...] or n[-m[:s]][ n[-m[:s]] ...]

and thus consists of a comma or blank separated list of range specifiers n[-m[:s]]. The ranges are concatenated to the complete task id range. Each range may be a single number, a simple range of the form n-m or a range with a step size.

wc_ar

The wildcard advance reservation (AR) specification is a placeholder for AR ids, AR names including AR name patterns. An AR id always references one AR, while the name and pattern might reference multiple ARs.

wc_ar := ar_id | ar_name | pattern

wc_ar_list

The wildcard advance reservation (AR) list specification allows to reference multiple ARs with one command.

wc_ar_list := wc_ar [ , wc_ar , ...]

wc_host

A wildcard host specification (wc_host) is a wildcard expression which might match one or more hosts used in the cluster. The first character of that string never begins with an at-character ('@'), even if the expression begins with a wildcard character.

 
 e.g.
 

* all hosts a* all host beginning with an 'a'

wc_hostgroup

 
 A wildcard hostgroup specification (wc_hostgroup) is a 
 wildcard expression which might match one or more hostgroups.
 The first character of that string is always an at-character ('@').
 

 
 More information concerning hostgroups can be found in
 
 

 
 

 
 e.g.
 

@* all hostgroups in the cluster @solaris the @solaris hostgroup

wc_job

 
 The wildcard job specification is a placeholder for job ids, job names 
 including job name patterns. A job id always references one
 job, while the name and pattern might reference multiple jobs.
 

 wc_job := job-id | job-name | pattern
 

 
 

wc_job_range

 
 The wildcard job range specification allows to reference specific array
 tasks for one or multiple jobs. The job is referenced via wc_job and in
 addition gets a range specifier for the array tasks.
 

 wc_job_range := wc_job [ -t range]
 

 
 

wc_job_list

 
 The wildcard job list specification allows to reference multiple jobs 
 with one command.
 

 
 wc_job_list := wc_job [ , wc_job , ...]
 

 
 

wc_job_range_list

 
 The wildcard job range list (wc_job_range_list) is specified by 
 one of the following forms:
 

 
 
 
    wc_job[ -t range][{, }wc_job[ -t range]{, }...]
 
 
 

 If present, the task_range restricts the effect of the qmod
 operation to the array job task range specified as suffix to the job id
 (see the -t option to
 
 for further details on array jobs).
 

 
 

wc_qdomain

 
 wc_qdomain := wc_cqueue "@" wc_hostgroup
 

 
 A wildcard expression queue domain specification (wc_qdomain) starts with a wildcard
 expression cluster queue name (wc_cqueue) followed by an at-character '@' 
 and a wildcard expression hostgroup specification (wc_hostgroup).
 

 
 wc_qdomain are used to address a group of queue instances.
 All queue instances residing on a hosts which is part of matching hostgroups
 will be addressed. Please note, that wc_hostgroup always begins with
 an at-character.
 

 
 

 
 e.g.
 

*@@* all queue instances whose underlying host is part of at least one hostgroup a*@@e* all queue instances begins with a whose underlying host is part of at least one hostgroup begin with e *@@solaris all queue instances on hosts part of the @solaris hostgroup

wc_cqueue

 
 A wildcard expression cluster queue specification (wc_cqueue) is a 
 wildcard expression which might match one or more cluster queues used in the cluster.
 That string never contains an at-character ('@'), even if the expression begins with a 
 wildcard character.
 

 
 
 

 
 e.g.
 

* all cluster queues a* all cluster queues beginning with an 'a' a*&!adam all cluster queues beginning with an 'a',but not adam

wc_qinstance

 
 wc_qinstance := wc_cqueue "@" wc_host
 

 
 A wildcard expression queue instance specification (wc_qinstance) starts 
 with a wildcard expression cluster queue name (wc_cqueue) followed by an 
 at-character '@' and a wildcard expression hostname (wc_host).
 

 
 wc_qinstance expressions are used to address a group
 of queue instances whose underlying hostname matches the given expression.
 Please note that the first character of wc_host does never match 
 the at-character '@'. 
 

 
 

 
 e.g.
 

*@* all queue instances in the cluster *@b* all queue instances whose hostname begins with a 'b' *@b*|c* all queue instances whose hostname begins with a 'b' or 'c'

wc_queue

 
 wc_queue := wc_cqueue | wc_qdomain | wc_qinstance 
 

 
 A wildcard queue expression (wc_queue) might either be a wildcard expression 
 cluster queue specification (wc_cqueue) or a wildcard expression queue domain
 specification (wc_qdomain) or a wildcard expression queue instance specification
 (wc_qinstance).
 

 
 

 
 e.g.
 

big_*1 cluster queues which begin with "big_" and end with "1" big_*&!*1 cluster queues which begin with "big_" ,but does not end with "1" *@fangorn all qinstances residing on host fangorn

wc_queue_list

 
 wc_queue_list := wc_queue ["," wc_queue "," ...]
 

 
 Comma separated list of wc_queue elements.
 

 
 e.g. 
 

big, medium_*@@sol*, *@fangorn.sun.com

wc_user

 
 A wildcard user name pattern is either a wildcard user name specification
 or a full user name.
 

 
 wc_user := user_name | pattern
 

 
 

wc_user_list

 
 A list of user names.
 

 
 wc_user_list := wc_user [ , wc_user , ...]
 

 
 

wc_project

 
 A wildcard project name pattern is either a wildcard project name specification
 or a full project name.
 

 
 wc_project := project | pattern
 

 
 

wc_pe_name

 
 A wildcard parallel environment name pattern is either a wildcard pe name specification
 or a full pe name.
 

 
 wc_pe_name := pe_name | pattern
 

 
 

parallel_env n[-[m]]|[-]m,...

 
 Parallel programming environment (PE) to select for an AR. The
 range descriptor behind the PE name specifies the number of
 parallel processes to be run. Grid Engine will allocate the
 appropriate resources as available. The
 
 manual page contains information about the definition of PEs
 and about how to obtain a list of currently valid PEs.
 

 
 You can specify a PE name which uses the wildcard character, "*".  Thus
 the request "pvm*" will match any parallel environment with a name
 starting with the string "pvm". In the case of multiple parallel environments
 whose names match the name string, the parallel environment with the most
 available slots is chosen.
 

 
 The range specification is a list of range expressions of the
 form "n-m", where n and m are positive, non-zero integers.  The form "n" is
 equivalent to "n-n".  The form "-m" is equivalent to "1-m".  The form "n-" is
 equivalent to "n-infinity".  The
 range specification is processed as follows: The largest
 number of queues requested is checked first. If enough queues
 meeting the specified attribute list are available, all are
 reserved. If not, the next smaller number of queues is checked,
 and so forth.
 

 
 

date_time

 
 The date_time value must conform to [[CC]]YY]MMDDhhmm[.SS], where:
 

 
 

 
 e.g.
 

CC denotes the century in 2 digits. YY denotes the year in 2 digits. MM denotes the month in 2 digits. DD denotes the day in 2 digits. hh denotes the hour in 2 digits. mm denotes the minute in 2 digits. ss denotes the seconds in 2 digits (default 00).

time

 
 The time value must conform to hh:mm:ss, or seconds where:
 

 
 

 
 e.g.
 

hh denotes the hour in 2 digits. mm denotes the minute in 2 digits. ss denotes the seconds in 2 digits (default 00). seconds is a number of seconds (is used for duration values)
If any of the optional date fields are omitted, the corresponding value of the current date is assumed. If CC is not specified, a YY of < 70 means 20YY.
Use of this option may cause unexpected results if the clocks of the hosts in the Grid Engine pool are out of sync. Also, the proper behavior of this option very much depends on the correct setting of the appropriate timezone, e.g. in the TZ environment variable (see for details), when the Grid Engine daemons and are invoked.

name

 
 The name
 may be any arbitrary alphanumeric ASCII string,
 but may not contain  "\n", "\t", "\r", "/", ":", "@", "\", "*",  or "?".
