<BODY>
<FORM name=config>
<H1>Slurm Version 20.02 Configuration Tool - Easy Version</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="file:///usr/share/doc/slurmctld/slurm-wlm-configurator.html">slurm-wlm-configurator.html</a>.</p>
<P><B>This tool supports Slurm version 20.02 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="https://slurm.schedmd.com/slurm.html">https://slurm.schedmd.com/slurm.html</A>
<H2>Control Machines</H2>
Define the hostname of the computer on which the Slurm controller and
optional backup controller will execute.
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>SlurmctldHost</B>:
Primary Controller Hostname
<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><font color="green">NodeName</font></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><font color="green">PartitionName</font></B>:
Name of the one partition to be created
<P>
<input type="text" name="max_time" value="INFINITE"> <B><font color="green">MaxTime</font></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><font color="red">SlurmUser</font></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/lib/slurm/slurmctld"> <B><font color="red">StateSaveLocation</font></B>:
Slurmctld state save directory </B>
<P>
<input type="text" name="slurmd_spool_dir" value="/var/lib/slurm/slurmd"> <B><font color="red">SlurmdSpoolDir</font></B>:
Slurmd state save directory

Select one value for <B>SwitchType</B>:<BR>
<input type="radio" name="switch_type" value="cray_aries"> <B>Cray XC</B>: Cray XC proprietary interconnect<BR>
<input type="radio" name="switch_type" value="none" checked> <B>None</B>: No special
handling required (InfiniBand, Myrinet, Ethernet, etc.)<BR>
<P>
<H2>Default MPI Type</H2>
Specify the type of MPI to be used by default. Slurm will configure environment
variables accordingly. Users can over-ride this specification with an srun option.<BR>
Select one value for <B>MpiDefault</B>:<BR>
<input type="radio" name="mpi_default" value="pmi2"> <B>MPI-PMI2</B>
(For PMI2-supporting MPI implementations)<BR>

<H2>Event Logging</H2>
Slurmctld and slurmd daemons can each be configured with different
levels of logging verbosity from 0 (quiet) to 7 (extremely verbose).
Each may also be configured to use debug files. Use fully qualified
pathnames for the files.
