 <BODY>
 <FORM name=config>
 <H1>SLURM Version @SLURM_MAJOR@.@SLURM_MINOR@ Configuration Tool</H1>
 <P>This form can be used to create a SLURM configuration file with
 you controlling many of the important configuration parameters.</P>

 <p>This is a simplified version of the SLURM configuration tool. This version
 has fewer  options for creating a SLURM configuration file. The full version
 of the SLURM configuration tool is available at
 <a href="configurator.html">configurator.html</a>.</p>

 <P><B>This tool supports SLURM version @SLURM_MAJOR@.@SLURM_MINOR@ only.</B>
 Configuration files for other versions of SLURM should be built
 using the tool distributed with it in <i>doc/html/configurator.html</i>.
 Some parameters will be set to default values, but you can
 manually edit the resulting <I>slurm.conf</I> as desired
 for greater flexibility. See <I>man slurm.conf</I> for more
 details about the configuration parameters.</P>

 <P>Note the while SLURM daemons create log files and other files as needed,
 it treats the lack of parent directories as a fatal error.
 This prevents the daemons from running if critical file systems are
 not mounted and will minimize the risk of cold-starting (starting
 without preserving jobs).</P>

 <P>Note that this configuration file must be installed on all nodes
 in your cluster.</P>

 <P>After you have filled in the fields of interest, use the
 "Submit" button on the bottom of the page to build the <I>slurm.conf</I>
 file. It will appear on your web browser. Save the file in text format
 as <I>slurm.conf</I> for use by SLURM.

 <P>For more information about SLURM, see
 <A HREF="http://www.schedmd.com/slurmdocs/slurm.html">http://www.schedmd.com/slurmdocs/slurm.html</A>

 <H2>Control Machines</H2>
 Define the hostname of the computer on which the SLURM controller and
 optional backup controller will execute. You can also specify addresses
 of these computers if desired (defaults to their hostnames).
 The IP addresses can be either numeric IP addresses or names.
 Hostname values should should not be the fully qualified domain
 name (e.g. use <I>tux</I> rather than <I>tux.abc.com</I>).
 <P>
 <input type="text" name="control_machine" value="linux0"> <B>ControlMachine</B>:
 Master Controller Hostname
 <P>
 <input type="text" name="control_addr"> <B>ControlAddr</B>: Master Controller
 Address (optional)
 <P>

 <H2>Compute Machines</H2>
 Define the machines on which user applications can run.
 You can also specify addresses of these computers if desired
 (defaults to their hostnames).
 Only a few of the possible parameters associated with the nodes will
 be set by this tool, but many others are available.
 Executing the command <i>slurmd -C</i> on each compute node will print its
 physical configuration (sockets, cores, real memory size, etc.), which
 can be used in constructing the <i>slurm.conf</i> file.
 All of the nodes will be placed into a single partition (or queue)
 with global access. Many options are available to group nodes into
 partitions with a wide variety of configuration parameters.
 Manually edit the <i>slurm.conf</i> produced to exercise these options.
 Node names and addresses may be specified using a numeric range specification.

 <P>
 <input type="text" name="node_name" value="linux[1-32]"> <B>NodeName</B>:
 Compute nodes
 <P>
 <input type="text" name="node_addr"> <B>NodeAddr</B>: Compute node addresses
 (optional)
 <P>
 <input type="text" name="partition_name" value="debug"> <B>PartitionName</B>:
 Name of the one partition to be created
 <P>
 <input type="text" name="max_time" value="INFINITE"> <B>MaxTime</B>:
 Maximum time limit of jobs in minutes or INFINITE
 <P>
 The following parameters describe a node's configuration.
 Set a value for <B>CPUs</B>.
 The other parameters are optional, but provide more control over scheduled resources:
 <P>
 <input type="text" name="procs" value="1"> <B>CPUs</B>: Count of processors
 on each compute node.
 If CPUs is omitted, it will be inferred from:
 Sockets, CoresPerSocket, and ThreadsPerCore.
 <P>
 <input type="text" name="sockets" value="">
 <B>Sockets</B>:
 Number of physical processor sockets/chips on the node.
 If Sockets is omitted, it will be inferred from:
 CPUs, CoresPerSocket, and ThreadsPerCore.
 <P>
 <input type="text" name="cores_per_socket" value="">
 <B>CoresPerSocket</B>:
 Number of cores in a single physical processor socket.
 The CoresPerSocket value describes physical cores, not
 the logical number of processors per socket.
 <P>
 <input type="text" name="threads_per_core" value="">
 <B>ThreadsPerCore</B>:
 Number of logical threads in a single physical core.
 <P>
 <input type="text" name="memory" value=""> <B>RealMemory</B>: Amount
 of real memory. This parameter is required when specifying Memory as a
 consumable resource with the select/cons_res plug-in. See below
 under Resource Selection.
 <P>

 <H2>SLURM User</H2>
 The SLURM controller (slurmctld) can run without elevated privileges,
 so it is recommended that a user "slurm" be created for it. For testing
 purposes any user name can be used.
 <P>
 <input type="text" name="slurm_user" value="slurm"> <B>SlurmUser</B>
 <P>

 <H2>State Preservation</H2>
 Define the location of a directory where the slurmctld daemon saves its state.
 This should be a fully qualified pathname which can be read and written to
 by the SLURM user on both the control machine and backup controller (if configured).
 The location of a directory where slurmd saves state should also be defined.
 This must be a unique directory on each compute server (local disk).
 The use of a highly reliable file system (e.g. RAID) is recommended.
 <P>
 <input type="text" name="state_save_location" value="/var/spool"> <B>StateSaveLocation</B>:
 Slurmctld state save directory </B>
 <P>
 <input type="text" name="slurmd_spool_dir" value="/var/spool/slurmd"> <B>SlurmdSpoolDir</B>:

 Using values defined in the configuration file will provide faster scheduling.<BR>
 Select one value for <B>FastSchedule</B>:<BR>
 <input type="radio" name="fast_schedule" value="1" checked>
 <B>1</B>: Use node configuration values defined in configuration file<BR>
 <input type="radio" name="fast_schedule" value="0">
 <B>0</B>: Use node configuration values actually found on each node
 (if configured with with gang scheduling or allocation of individual
 processors to jobs rather than only whole node allocations, the processor
 count on the node should match the configured value to avoid having extra
 processors left idle)
 <P>

 <H2>Interconnect</H2>
 Define the node interconnect used.<BR>
 Select one value for <B>SwitchType</B>:<BR>
 <input type="radio" name="switch_type" value="elan"> <B>Elan</B>: Quadrics Elan3 or Elan4<BR>

 variables accordingly. Users can over-ride this specification with an srun option.<BR>
