qrsub - Submit an Advance Reservation (AR) to Sun Grid

Qrsub provides a means for operators, managers or users
referenced in the ACL (see access_list(5)) "arusers" to
create a Advance Reservation (AR) in the Sun Grid Engine
queuing system. ARs allow to reserve particular consumable
resources for future use. These reserved resources are only
available for jobs requesting the AR and the scheduler
ensures the availability of the resources when the start
time is reached. Job requesting the AR can only use the
reserved consumable resources.
During AR submit time the Sun Grid Engine queuing system
selects the best suited queues for the AR request and then
reserves the desired amount of resources. For a reserva-
tion, all queues that are not in orphaned state are con-
sidered as suited. Only if the AR request can be fulfilled,
the AR will be granted.
ARs will be deleted either automatically when the end time
is reached, or manually using qrdel . In both cases, first
all jobs requesting the AR will be removed and then AR
itself. Already granted ARs can be shown with qrstat(.)
Note: To make AR behavior predictable, it is necessary to
have reserved resources available at the time of AR start.
This is done by keeping jobs with a unlimited runtime limit
separated from ARs, and not considering resources used by
such jobs for reservation.
Note: Resource Quotas are not considered for AR queue selec-
tion and nor for jobs requesting a AR.
When an AR was successfully added to the Sun Grid Engine
queuing system qrsub returns a unique integer ID referring
the the newly created AR. The highest AR ID is 9999999. If
the highest ID is reached, a wraparound happens and the next
unused ID, starting with 1, will be used.
For qrsub, the administrator and the user may define default
request files (analogous to Sun Grid Engine_request for
qsub), which can contain any of the possible command line
A cluster wide default request file is optional. If such a
default request file is used, it must be placed under
$SGE_ROOT/$SGE_CELL/common/sge_ar_request (global defaults
A user private default request file is optional. If it is
used, it must be placed under
$HOME/.sge_ar_request (user private defaults file).
Defines the activation (start) date and time of an AR.
The option is not mandatory. If omitted, the current
date_time is assumed. Either a duration or end
date_time must also be specified. For details about
date_time please see sge_types(1)
Identifies the account to which the resource reserva-
tion of the AR should be charged. For "account_string"
value details please see the "name" definition in
sge_types(1). In the absence of this parameter Sun
Grid Engine will place the default account string "sge"
in the accounting record of the AR.
Selects the checkpointing environment (see check-
point(5)) the AR jobs may request. Using this option
guarantees queues that only providing this checkpoint
environment will be reserved.
Defines the duration of the AR. The use of "-d time" is
optional if "-e date_time" is requested. For details
about "time" definition please see sge_types(1).
Defines the end date and time of an AR. The use of "-e
date_time" is optional if "-d time" is requested. For
details about "date_time" definition please see
Specifies the behavior when the AR goes into an error
state. The AR goes into error state when a reserved
host goes into unknown state, a queue error happens, or
when a queue is disabled or suspended.
A hard error, "-he yes", means as long as the AR is in
error state no jobs using the AR will be scheduled. If
soft error, "-he no", is specified the AR stays usable
with the remaining resources.
By default soft error handling is used.
Prints a list of all options.
Creates an AR in a Sun Grid Engine queue, providing the
given resource request list. complex(5) describes how
a list of available resources and their associated
valid value specifiers can be obtained.
There may be multiple -l switches in a single command.
Defines or redefines under which circumstances mail is
to be sent to the AR owner or to the users defined with
the -M option described below. The option arguments
have the following meaning:
`b' Mail is sent at the beginning of the AR
`e' Mail is sent at the end of the AR
`a' Mail is sent when the AR goes into error state
`n' No mail is sent, default for qrsub
Defines or redefines the list of users to which the
qmaster sends mail.
Only meaningful for a parallel AR request together with
the -pe option.
This option is used to reserve the proper queues to
match this request if it would be requested by a qsub.
A more detailed description of wc_queue_list can be
found in sge_types(1).
This options impacts the queues selection for reserva-
With the "-now y" option, only queues with the qtype
"INTERACTIVE" assigned will be considered for reserva-
tion. "-now n" is the default for qrsub.
The name of the AR. The name, if requested, must con-
form to "name" as defined in sge_types(1). Invalid
names will be denied at submit time.
Specifies the validation level applied to the AR
The specifiers e and v define the following validation
`v' verify - does not submit the AR but prints
an extensive validation report
`e' error - rejects request if requirements cannot
be fulfilled, default for qrsub
-pe parallel_env n[-[m]]|[-]m,...
Parallel programming environment (PE) to select for the
AR queue reservation. Please see the details of a PE in
Defines or redefines a list of cluster queues, queue
domains or queue instances, that may be reserved by the
AR. Please find a description of wc_queue_list in
sge_types(1). This parameter has all the properties of
a resource request and will be merged with requirements
derived from the -l option described above.
Defines the users allowed to submit jobs requesting the
AR. The access is specified by a comma separated list
containing UNIX users or ACLs (see access_list(5)).
prefixing the ACL name with an '@' sign.
By default only the AR owner is allowed to submit jobs
requesting the AR.
Note: Only queues, where all users specified in the
list have access, are considered for reservation (see

If set, specifies that debug information
should be written to stderr. In addition the
level of detail in which debug information is
generated is defined.
If set, specifies the TCP port on which
sge_qmaster(8) is expected to listen for com-
munication requests. Most installations will
use a services map entry for the service
"sge_qmaster" instead of defining the port.
