help="""\
-binding [ binding_instance ] binding_strategy
A job can request a specific processor core binding (processor affinity)
with this parameter. This request is neither a hard nor a soft request,
it is a hint for the execution host to do this if possible. Please note that
the requested binding strategy is not used for resource selection within
Grid Engine. As a result an execution host might be selected where Grid Engine
does not even know the hardware topology and therefore is not able
to apply the requested binding.
To enforce Grid Engine to select hardware on which the binding can be applied
please use the -l switch in combination with the complex attribute m_topology.
binding_instance is an optional parameter.
It might either be env, pe or set depending on which instance should
accomplish the job to core binding. If the value for binding_instance
is not specified then set will be used.
env means that the environment variable SGE_BINDING will be exported
to the job environment of the job. This variable contains the selected
operating system internal processor numbers. They might be more than selected
cores in presence of SMT or CMT because each core could be represented
by multiple processor identifiers. The processor numbers are space separated.
pe means that the information about the selected cores appears in
the fourth column of the pe_hostfile. Here the logical core and
socket numbers are printed (they start at 0 and have no holes)
in colon separated pairs (i.e. 0,0:1,0 which means core 0 on socket 0 and
core 0 on socket 1). For more information about the $pe_hostfile
check ge_pe(5)
set (default if nothing else is specified). The binding strategy is applied
by Grid Engine. How this is achieved depends on the underlying hardware
architecture of the execution host where the submitted job will be started.
On Solaris 10 hosts a processor set will be created where the job can
exclusively run in. Because of operating system limitations at least
one core must remain unbound. This resource could of course used by an unbound job.
On Linux hosts a processor affinity mask will be set to restrict the job
to run exclusively on the selected cores.
The operating system allows other unbound processes to use these cores.
Please note that on Linux the binding requires a Linux kernel
version of 2.6.16 or greater. It might be even possible to use a kernel with
lower version number but in that case additional kernel patches have to be
applied. The loadcheck tool in the utilbin directory can be used to check
if the hosts capabilities. You can also use the -sep in combination with
-cb of qconf(5) command to identify if Grid Engine is able to recognize the
hardware topology.
Possible values for binding_strategy are as follows:
linear:<amount>[:<socket>,<core>]
striding:<amount>:<n>[:<socket>,<core>]
explicit:[<socket>,<core>;...]<socket>,<core>
For the binding strategy linear and striding there is an optional
socket and core pair attached.
These denotes the mandatory starting point for the first core to bind on.
linear means that Grid Engine tries to bind the job on amount successive cores.
If socket and core is omitted then Grid Engine first allocates successive cores
on the first empty socket found. Empty means that there are
no jobs bound to the socket by Grid Engine. If this is not possible or is
not sufficient Grid Engine tries to
find (further) cores on the socket with the most unbound cores and so on.
If the amount of allocated cores is
lower than requested cores, no binding is done for the job.
If socket and core is specified then Grid Engine
tries to find amount of empty cores beginning with this starting point.
If this is not possible then binding is not done.
striding means that Grid Engine tries to find cores with a certain offset.
It will select amount of empty cores with a offset of n -1 cores in between.
Start point for the search algorithm is socket 0 core 0. As soon as
amount cores are found they will be used to do the job binding.
If there are not enough empty cores or if correct offset cannot be
achieved then there will be no binding done.
explicit binds the specified sockets and cores that are mentioned
in the provided socket/core list. Each socket/core pair has to
be specified only once.If a socket/core pair is already in use by a different job the
whole binding request will be ignored.
Qalter allows changing this option even while the job executes.
The modified parameter will only be in effect
after a restart or migration of the job, however.
If this option or a corresponding value in qmon is specified then these values
will be passe to defined JSV instances as parameters with the names binding_strategy,
binding_type, binding_amount, binding_step, binding_socket,
binding_core, binding_exp_n, binding_exp_socket<id>, binding_exp_core<id>.
Please note that the length of the socket/core value list of the explicit binding is
reported as binding_exp_n.
<id> will be replaced by the position of the socket/core pair within the explicit
list (0 <= id < binding_exp_n). The first socket/core pair of the explicit
binding will be reported with the parameter names bind-
ing_exp_socket0 and binding_exp_core0.
Values that do not apply for the specified binding will not be reported to JSV.
E.g. binding_step will only be
reported for the striding binding and all binding_exp_* values will passed to
JSV if explicit binding was speci‐
fied. (see -jsv option below or find more information concerning
JSV in jsv(1))""")

Available for qsub, qrsh only. Qalter does not allow changing this option.
This option cannot be embedded in the script file itself.
Gives the user the possibility to indicate explicitly whether command should be
treated as binary or script. If the value of -b is 'y', then command may be a
binary or script. The command might not be accessible from the
submission host. Nothing except the path of the command will be
transferred from the submission host to the
execution host. Path aliasing will be applied to the path of command
before command will be executed.
If the value of -b is 'n' then command needs to be a script and it will
be handled as script. The script file
has to be accessible by the submission host.
It will be transferred to the execution host. qsub/qrsh will search
directive prefixes within script.
qsub will implicitly use -b n whereas qrsh will apply the -b y option
if nothing else is specified.
The value specified with this option or the corresponding value
specified in qmon will only be passed to defined
JSV instances if the value is yes. The name of the parameter will be b.
The value will be y also when then long
form yes was specified during submission.
(see -jsv option below or find more information concerning JSV in
jsv(1))
Please note that submission of command as script (-b n) can have a
significant performance impact,especially for short running jobs and big job scripts.
Script submission adds a number of operations to the submission
process: The job script needs to be
- parsed at client side (for special comments)
- transferred from submit client to qmaster
- spooled in qmaster
- transferred to execd at job execution
- spooled in execd
- removed from spooling both in execd and qmaster once the job is done
If job scripts are available on the execution nodes, e.g. via NFS, binary
submission can be the better choice.""")

-e [[hostname]:]path,...
Available for qsub, qsh, qrsh, qlogin and qalter only.
Defines or redefines the path used for the standard error stream of the job.
For qsh, qrsh and qlogin only the
standard error stream of prolog and epilog is redirected. If the path
constitutes an absolute path name, the
error-path attribute of the job is set to path, including the hostname.
If the path name is relative, Grid
Engine expands path either with the current working directory path
(if the -cwd switch (see above) is also spec‐
ified) or with the home directory path. If hostname is present,
the standard error stream will be placed in the
corresponding location only if the job runs on the specified host.
If the path contains a ":" without a host‐
name, a leading ":" has to be specified.
By default the file name for interactive jobs is /dev/null.
For batch jobs the default file name has the form
job_name.ejob_id and job_name.ejob_id.task_id for array job tasks (see -t option
below).
If path is a directory, the standard error stream of the job will be put
in this directory under the default
file name. If the pathname contains certain pseudo environment variables,
their value will be expanded at run‐
time of the job and will be used to constitute the standard error stream path name.
The following pseudo envi‐
ronment variables are supported currently:
$HOME home directory on execution machine
$USER user ID of job owner
$JOB_ID current job ID
$JOB_NAME current job name (see -N option)
$HOSTNAME name of the execution host
$TASK_ID array job task index number
Alternatively to $HOME the tilde sign "~" can be used as common in csh(1)
or ksh(1). Note, that the "~" sign
also works in combination with user names, so that "~<user>" expands to the
home directory of <user>. Using
another user ID than that of the job owner requires corresponding permissions,
of course.

As Grid Engine scans the command line and script file for Grid Engine options

List of holds to place on a job, a task or some tasks of a job.
`u' denotes a user hold.
`s' denotes a system hold.
`o' denotes a operator hold.
`n' denotes no hold (requires manager privileges).
As long as any hold other than `n' is assigned to the job the job is

fiers for the -h switch:
`U' removes a user hold.
`S' removes a system hold.
`O' removes a operator hold.
Grid Engine managers can assign and remove all hold types,
Grid Engine operators can assign and remove user and
operator holds, and users can only assign or remove user holds.
In the case of qsub only user holds can be placed on a job and thus

Available only for qrsh and qmake(1).
qrsh allows the user to start a task in an already scheduled parallel job.
The option -inherit tells qrsh to
read a job id from the environment variable JOB_ID and start the
specified command as a task in this job. Please
note that in this case, the hostname of the host where the command
will be executed must precede the command to
execute; the syntax changes to
qrsh -inherit [ other options ] hostname command [ command_args ]
Note also, that in combination with -inherit, most other command line
options will be ignored. Only the options
-verbose, -v and -V will be interpreted. As a replacement to option
-cwd please use -v PWD.
Usually a task should have the same environment (including the
current working directory) as the corresponding
job, so specifying the option -V should be suitable for most applications.
Note: If in your system the qmaster tcp port is not configured as a service,
but rather via the environment
variable GE_QMASTER_PORT, make sure that this variable is set in the
environment when calling qrsh or qmake with
the -inherit option. If you call qrsh or qmake with the
-inherit option from within a job script, export
GE_QMASTER_PORT with the option "-v GE_QMASTER_PORT" either as
a command argument or an embedded directive.

Defines or redefines the job share of the job relative to other jobs.
Job share is an unsigned integer value.
The default job share value for jobs is 0.
The job share influences the Share Tree Policy and the Functional Policy.
It has no effect on the Urgency and
Override Policies (see share_tree(5), sched_conf(5) and the
Grid Engine Installation and Administration Guide
for further information on the resource management policies supported
by Grid Engine).
In case of the Share Tree Policy, users can distribute the tickets to
which they are currently entitled among
their jobs using different shares assigned via -js.
If all jobs have the same job share value, the tickets are
distributed evenly. Otherwise, jobs receive tickets relative
to the different job shares. Job shares are treated
like an additional level in the share tree in the latter case.
In connection with the Functional Policy, the job share can be
used to weight jobs within the functional job
category. Tickets are distributed relative to any uneven
job share distribution treated as a virtual share dis‐
tribution level underneath the functional job category.
If both the Share Tree and the Functional Policy are active,
the job shares will have an effect in both poli‐
cies, and the tickets independently derived in each of them are
added to the total number of tickets for each
job.

Following restrictions apply to the values n and m:
1 <= n <= MIN(2^31-1, max_aj_tasks)
1 <= m <= MIN(2^31-1, max_aj_tasks)
n <= m
max_aj_tasks is defined in the cluster configuration (see sge_conf(5))
The task id range specified in the option argument may be a single
number, a simple range of the form n-m or a
range with a step size. Hence, the task id range specified by
2-10:2 would result in the task id indexes 2, 4,
6, 8, and 10, for a total of 5 identical tasks, each with
the environment variable GE_TASK_ID containing one of
the 5 index numbers.
All array job tasks inherit the same resource requests and
attribute definitions as specified in the qsub or
qalter command line, except for the -t option.
The tasks are scheduled independently and, provided enough
resources exist, concurrently, very much like separate jobs.
However, an array job or a sub-array there of can
be accessed as a single unit by commands like qmod(1) or qdel(1).
See the corresponding manual pages for fur‐
ther detail.
Array jobs are commonly used to execute the same type of operation
on varying input data sets correlated with
the task index number. The number of tasks in a array job is unlimited.
STDOUT and STDERR of array job tasks will be written into different
files with the default location
<jobname>.['e'|'o']<job_id>'.'<task_id>
In order to change this default, the -e and -o options (see above)
can be used together with the pseudo environ‐
ment variables $HOME, $USER, $JOB_ID, $JOB_NAME, $HOSTNAME, and $GE_TASK_ID.
Note, that you can use the output redirection to divert the output
of all tasks into the same file, but the
result of this is undefined.
If this option or a corresponding value in qmon is specified
then this value will be passed to defined JSV
instances as parameters with the name t_min, t_max and t_step

concerning JSV in jsv(1))""")

Available for qsub, qsh, qrsh, qlogin and qalter.
Specifies a validation level applied to the job to be submitted
(qsub, qlogin, and qsh) or the specified queued
job (qalter). The information displayed indicates whether the
job can possibly be scheduled assuming an empty
system with no other jobs. Resource requests exceeding the
configured maximal thresholds or requesting unavail‐
able resource attributes are possible causes for jobs to fail this validation.
The specifiers e, w, n and v define the following validation modes:
`e' error - jobs with invalid requests will be
rejected.
`w' warning - only a warning will be displayed
for invalid requests.
`n' none - switches off validation; the default for
qsub, qalter, qrsh, qsh
and qlogin.
`p' poke - does not submit the job but prints a
validation report based on a cluster as is with
all resource utilizations in place.
`v' verify - does not submit the job but prints a
validation report based on an empty cluster.
Note, that the necessary checks are performance consuming
and hence the checking is switched off by default. It
should also be noted that load values are not taken
into account with the verification since they are assumed to
be too volatile. To cause -w e verification to be passed
at submission time, it is possible to specify non-
volatile values (non-consumables) or maximum values
(consumables) in complex_values.""")
