qmon(1)
NAME
qmon - X-Windows OSF/Motif graphical user interface for Grid Engine
SYNTAX
qmon [options]
DESCRIPTION
Qmon allows administrators and users to manipulate the Grid Engine
system from an X-Window environment. Qmon provides various dialogues
linked together in multiple ways. For each task the user wishes to
accomplish via qmon a corresponding dialogue is provided. There are
multiple ways to address the proper dialogue for a certain task:
* The qmon main window that comes up first on start-up contains icon
buttons for all major administrative and user tasks. A functionality
tooltip is displayed when pointing at the different icons.
* A Task pulldown menu button appears in the qmon main window menu
bar. Clicking on it opens a list of available tasks. Selecting one
of them opens the corresponding dialogue.
* The Task pulldown menu also contains the key accelerators which can
be used to invoke the task dialogues directly from the main window
by pressing a certain sequence on the keyboard.
* While navigating through a certain dialogue and its dialogue sub-
hierarchy, links to other dialogues occur whenever a connection
between both dialogues is obvious. Pushing the buttons that identify
the links opens up the other dialogues.
OPTIONS
The supported options are the standard X Toolkit options as described
in X(1) section Options. Furthermore, qmon supports:
-cmap Installs a private color map for qmon. This is sometimes useful
if other applications have already allocated lots of colors and
if qmon, therefore prints corresponding error messages. Note,
however, that using a private color map will result in color map
switches whenever you enter or leave qmon windows.
-fontFamily {big|medium|small}
Notifies qmon to use different size font families for different
resolution sizes.
-help Displays usage information.
-nologo
Startup without logo.
DIALOGUES
Job Control
The Job Control dialogue provides a folder of tabulated lists of the
still pending jobs, already running jobs and recently finished jobs.
The dialogue allows for detailed information on the jobs as well as for
the deletion and suspension of jobs being selected. In addition the
job control dialogue offers links to the Submit dialogue in order to
submit new jobs or to change attributes of pending jobs (Qalter
button). The fields displayed in the tabular display and the jobs
displayed can be customized by pressing the Customize button. This
customization can be saved to the ~/.qmon_preferences file and is used
on following startup for the initial configuration of the Job Control
dialogue.
Queue Control
The Queue Control dialogue with its sub-dialogue hierarchy enables the
user to control the status of the Grid Engine queues actually
configured in the system and allows the administrator to add new queues
or to modify or delete existing ones. The Queue Control dialogue shows
a tabbed view of Cluster Queues or their corresponding Queue Instances
in a tabular way.
By pushing the Add, Clone or Modify button, a sub-dialogue for
configuring Grid Engine queues is opened. A queue needs to be selected
to use the clone and modify operation. The configuration sub-dialogue
allows for definition of the queue and its attributes. The
configuration sub-dialogue contains in the upper section the queue name
and a list of hosts or hostgroups for which this queue contains the
configuration. The lower section contains a list of hosts or
hostgroups at the left, where the default attributes are shown when the
"@/" entry is highlighted. These default attributes can be overruled
on a hostgroup or host basis by enabling attributes and changing their
values after this hostgroup or host entry has been added in the
"Attributes for Host/Hostgroup" listbox. The queue configuration
parameters (see queue_conf(5)) are subdivided into different categories
(General Configuration, Execution Methods, Checkpointing, Load/Suspend
Thresholds, Limits, Complexes, User Access, Project Access, Subordinate
Queues, Owners) which are selectable by the tab widget area presented
in the lower region of the queue configuration sub-dialogue. The
administrator may select previously-configured settings from already
existing queues (Clone button). By pushing the Ok button, the
definitions are registered with sge_qmaster(8). The Queue Control
dialogue can be customized in a similar way as the Job Control
dialogue. The settings applied here are also saved in
~/.qmon_preferences.
Submit
The Job Submission dialogue serves for submitting batch and interactive
jobs and is also invoked when changing attributes of pending jobs from
the Job Control dialogue explained above (Qalter button). To toggle
between batch and interactive jobs please use the Batch/Interactive
button at the top of the button column on the right side of the Job
Submission screen.
The dialogue consists of a folder containing two job preparation
dialogue pages. The most frequently used parameters in the course of a
job submission are offered on the General page. A job script has to be
defined; all other fields are optional. If the job demands
specification of advanced requirements, the Advanced tab can be used to
switch to an enhanced parameter display.
If resource requirements are mandatory for the job, the Request
Resources icon button has to be used to pop up the Requested Resources
sub-dialogue. This sub-dialogue allows for selection of the required
resources of the job and for definition of the quantities in which this
resources are to be provided. The Available Resources are constituted
from those complex attributes declared requestable (see complex(5) for
details). Resource requirements can be made Hard, i.e. they must be met
before a job can be started in a queue, or Soft, i.e. they are granted
on an as-available basis.
Closing the Requested Resources sub-dialogue with the done button books
the specified requirement for the job. Pushing the Submit button on the
top level Submit dialogue submits the job.
Complex Config
The Complex Config allows the administrator to add new complex
attributes or to modify or delete existing ones (see complex(5)). The
complex configuration dialogue provides a tabulated list of the complex
attribute entries and an input region for the declaration of new or
modified entries. The Add button updates the tabulated list with a new
attribute. The Modify button changes a highlighted existing entry.
The Delete button removes the highlighted attributes. The Load and
Save buttons allow saving or reloading the whole attribute list to or
from file. The Ok button registers the additional or modified complex
attributes with sge_qmaster(8).
Host Config
Four types of host related lists can be maintained via the Host Config
dialogue:
Administration Hosts
Submit Hosts
Host Groups
Execution Hosts
The host list to be manipulated is selected via clicking at one of the
tabs named correspondingly. The first two host lists only provide for
adding or deleting entries, thereby allowing administrative or submit
permission for the hosts on the lists, or denying it otherwise
respectively. The host group list allows the manipulation of host
groups. Host groups can reference either other host groups or hosts.
The execution host list entries in addition provide the ability to
define scaling factors for the load sensors, consumable complex
attributes and access attributes (access, xaccess and projects,
xprojects) as described in complex(5). CPU, memory and I/O usage
reported for running jobs can be scaled in addition and the relative
performance of a host can be defined with the Resource Capability
Factor (see host_conf(5)).
Cluster Config
This dialogue maintains the cluster global configuration as well as
host specific derivatives (see sge_conf(5)). When opened, the dialogue
displays a selection list for all hosts which have a configuration
assigned. The special name "global" refers to the cluster global
configuration. By pushing the Add/Modify button a sub-dialogue is
opened, which allows for modification of the cluster configuration. For
host specific configurations the 'global' host specific configuration
fields are set insensitive and only the allowed parameters can be
manipulated.
Scheduler Config
The Scheduler Configuration dialogue provides the means to change the
behavior of the Grid Engine scheduler thread part of sge_qmaster(8)
process. The dialogue contains a representation for all scheduler
configuration parameters as described in sched_conf(5). It is
subdivided in the two sections General Parameters and Load Adjustments,
which can be selected via the corresponding tabs. The Ok button
registers any changes with sge_qmaster(8).
Calendar Config
The Calendar Config allows the administrator to add new calendars or to
modify or delete existing ones (see calendar_conf(5)). The dialogue
offers a selection list for the existing calendars and displays the
configuration of the one being selected. By pushing the Delete button,
the selected calendar is deleted from the configuration. Pushing the
Add/Modify button will open a calendar configuration dialogue, which
allows to create new calendars or which provides the means to change
the existing ones. The Ok button registers the additional or modified
calendar with sge_qmaster(8).
User Config
User permissions are controlled via the User Config dialogue. The tab
widget in the left section of the dialogue allows for selecting between
Configuration of Manager accounts.
Configuration of Operator accounts.
Definition of Usersets.
Definition of User accounts.
Those user accounts added to the list of manager or operator accounts
are given permission to act as managers or operators respectively when
accessing Grid Engine under their own account.
The userset lists are used together with the user_lists and xuser_lists
host, queue, project and cluster configuration parameters (see
queue_conf(5), project(5) and sge_conf(5)) to control access of users
to hosts, queues, projects and the entire cluster. A userset is just a
collection of user names and UNIX group names. Group names are
identified by prefixing them with a "@" sign. The already-defined
usersets are displayed in a selection list. These lists can be
modified, and new lists can be created, using the Userset definition
dialogue.
Usersets can be used as Access List and/or as Department required for
the so called Functional Policy and Override Policy (see Ticket Config
below).
User names can be added to the system as entries to the Grid Engine
user database (see user(5)); here a default project can be attached to
the user too. This can be done with the User sub-dialogue.
The Tickets button in the button list on the right side of the dialogue
opens the Ticket Config dialogue (see below).
PE Config
Parallel environment (PE) interfaces can be configured with this
dialogue. PE interfaces are necessary to describe how parallel
programming environments like PVM (Parallel Virtual Machine), MPI
(Message Passing Interface), or shared memory parallel systems, are to
be instantiated and to impose access restrictions onto the PEs. When
the dialogue is opened a list of the configured PEs is displayed,
together with the current configuration (see sge_pe(5)) of the selected
PE interface. To add new PE interfaces, or to modify existing ones, an
Add and a Modify button are available which open a PE interface
configuration sub-dialogue. After applying the changes and quitting
this sub-dialogue with the OK button, the new or modified PE interface
is registered with sge_qmaster(8).
Checkpoint Config
Checkpointing environment interfaces can be configured with this
dialogue. Checkpointing environments are necessary to describe the
attributes which the different checkpointing methods and their
derivatives on various operating system platforms supported by Grid
Engine have. When the dialogue is opened a list of the already
configured checkpointing environments is displayed together with the
current configuration (see checkpoint(5)) of the selected checkpointing
environment. To add new checkpointing environments, or to modify
existing ones, an Add and a Modify button is available which opens a
checkpointing environment configuration sub-dialogue. After applying
the changes and quitting this sub-dialogue with the OK button, the new
or modified checkpointing environment is registered with
sge_qmaster(8).
Ticket Conf
This dialogue offers an overview and editing screen for allocating
tickets to the share-based, functional and override scheduling
policies.
The Deadline Job button opens the User Conf dialogue box. Please
change to the Userset sub-dialogue and select the userset named
"deadlineusers". Only users of this userset may submit deadline jobs.
The Share Tree Policy button opens the dialogue for creating and
editing the Grid Engine share tree (see share_tree(5) and sched_conf(5)
for a description of the configuration parameters).
The Functional Policy button opens the dialogue for creating and
editing the allocation of the functional shares (see sched_conf(5),
access_list(5), project(5), queue_conf(5) and user(5) for a description
of the different types of functional shares and the configurable
weighting parameters).
The Override Policy button opens the dialogue for creating and editing
the allocation of override tickets (see access_list(5), project(5),
queue_conf(5) and user(5) for a description of the different types of
override tickets).
Project Conf
This button opens a dialog for creating projects.
The dialogue offers a selection list for the existing projects and
displays the configuration of the one being selected. By pushing the
Delete button, the selected project is deleted from the configuration.
Pushing the Add/Modify button will open a project configuration
dialogue, which allows creating new projects changing existing ones.
Project configuration in essence means giving or denying access to a
project for usersets (see User Conf above as well as project(5)). The
Ok button registers the additional or modified project with
sge_qmaster(8).
Browser
The Object Browser dialogue's purpose is manifold: First of all, Grid
Engine and qmon Messages, such as notification of error or success
concerning a previously taken action, can be displayed in the
dialogue's output window. Also the standard output and the standard
error output of qmon can be diverted to the Object Browser output
window.
Additionally the Object Browser can be used to display continuous
information about Grid Engine objects as the mouse pointer moves over
their representation as icons or table entries in other qmon dialogues.
Currently, only the display of the configuration of two Grid Engine
objects in two separate dialogues is supported:
* Queue configurations are displayed as soon as the mouse pointer
enters a queue icon in the top level Queue Control dialogue (see
above). This facility is activated by pushing the Queue button in
the Object Browser dialogue.
* Detailed job information is printed as soon as the user moves the
mouse pointer over a line in the Job Control dialogue (see above)
assigned to a running or pending job.
* Additionally job scheduling information is displayed in the browser
if the Why? button in the Job Control dialogue is pressed. In this
case the Browser dialogue is opened implicitly and any scheduling
related information is displayed.
Exit
The Exit icon button is not linked with a dialogue. Its sole purpose is
to close all active qmon dialogues and to exit the application.
RESOURCES
The available resources, their meaning and the syntax to be followed in order to modify them are described in the default qmon resource file (see the section Files below for the location of the resource file).
ENVIRONMENT VARIABLES
SGE_ROOT Specifies the location of the Grid Engine standard
configuration files.
SGE_CELL If set, specifies the default Grid Engine cell. To
address a Grid Engine cell qmon uses (in the order of
precedence):
The name of the cell specified in the environment
variable SGE_CELL, if it is set.
The name of the default cell, i.e. default.
SGE_DEBUG_LEVEL
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.
SGE_QMASTER_PORT
If set, specifies the tcp port on which sge_qmaster(8)
is expected to listen for communication requests. Most
installations will use a services map entry instead to
define that port.
SGE_LOAD_AVG Specify a load parameter (see load_parameters(5)) to use
instead of load_avg when displaying/selecting load
values.
RESTRICTIONS
If the line to be entered in an editing window is longer than the width of the window, then the text just runs off the end of the window.
