topology.conf(5)					     Slurm configuration file						  topology.conf(5)

NAME

       topology.conf - Slurm configuration file for defining the network topology

DESCRIPTION

       topology.conf is an ASCII file which describes the cluster's network topology for optimized job resource allocation.  The file location can
       be modified at system build time using the DEFAULT_SLURM_CONF parameter or at execution time by setting the  SLURM_CONF	environment  vari-
       able. The file will always be located in the same directory as the slurm.conf file.

       Parameter  names  are case insensitive.	Any text following a "#" in the configuration file is treated as a comment through the end of that
       line.  The size of each line in the file is limited to 1024 characters.	Changes to the configuration file  take  effect  upon  restart	of
       SLURM daemons, daemon receipt of the SIGHUP signal, or execution of the command "scontrol reconfigure" unless otherwise noted.

       The  network  topology  configuration  one  one	line  defining a switch name and its children, either node names or switch names.  SLURM's
       hostlist expression parser  is  used,  so  the  node  and  switch  names  need  not  be	consecutive  (e.g.  "Nodes=tux[0-3,12,18-20]"  and
       "Switches=s[0-2,4-8,12]" will parse fine).  An optional link speed may also be specified.

       The overall configuration parameters available include:

       SwitchName
	      The  name  of  a	switch.  This name is internal to SLURM and arbitrary.	Each switch should have a unique name.	This field must be
	      specified.

       Switches
	      Child switches of the named switch.  Either this option or the Nodes option must be specified.

       Nodes  Child Nodes of the named leaf switch.  Either this option or the Switches option must be specified.

       LinkSpeed
	      An optional value specifying the performance of this communication link.	The units used are arbitrary and this information is  cur-
	      rently not used.	It may be used in the future to optimize resource allocations.

NAME

       slurm_complete_job - Slurm job completion call

SYNTAX

       #include <slurm/slurm.h>

       int slurm_complete_job (
	    uint32_t job_id,
	    uint32_t job_return_code
       );

ARGUMENTS

       job_id Slurm job id number.

       job_return_code
	      Exit code of the program executed.

DESCRIPTION

       slurm_complete_job Note the termination of a job. This function may only be successfully executed by the job's owner or user root.

RETURN VALUE

       On success, zero is returned. On error, -1 is returned, and Slurm error code is set appropriately.

ERRORS

       SLURM_PROTOCOL_VERSION_ERROR Protocol version has changed, re-link your code.

       ESLURM_INVALID_JOB_ID the requested job id does not exist.

       ESLURM_ALREADY_DONE the specified job has already completed and can not be modified.

       ESLURM_ACCESS_DENIED the requesting user lacks authorization for the requested action (e.g. trying to delete or modify another user's job).

       ESLURM_INTERCONNECT_FAILURE failed to configure the node interconnect.

       SLURM_PROTOCOL_SOCKET_IMPL_TIMEOUT Timeout in communicating with SLURM controller.

NOTE

       These functions are included in the libslurm library, which must be linked to your process for use (e.g. "cc -lslurm myprog.c").
