NAME

6       slurmd - The compute node daemon for Slurm.

SYNOPSIS

10       slurmd [OPTIONS...]
11
12

DESCRIPTION

14       slurmd  is the compute node daemon of Slurm. It monitors all tasks run‐
15       ning on the compute node , accepts work (tasks),  launches  tasks,  and
16       kills running tasks upon request.
17
18       OPTIONS
19
20       -b     Report  node  rebooted  when  daemon restarted. Used for testing
21              purposes.
22
23
24       -c     Clear system locks as needed. This may  be  required  if  slurmd
25              terminated abnormally.
26
27
28       -C     Print actual hardware configuration and exit. The format of out‐
29              put is the same as used in slurm.conf to describe a node's  con‐
30              figuration plus it's uptime.
31
32
33       -d <file>
34              Specify  the  fully qualified pathname to the slurmstepd program
35              to be used for shepherding user job steps. This  can  be  useful
36              for testing purposes.
37
38       -D     Run  slurmd  in the foreground. Error and debug messages will be
39              copied to stderr.
40
41       -f <file>
42              Read configuration from the specified file. See NOTES below.
43
44       -G     Print  Generic  RESource  (GRES)   configuration   (based   upon
45              slurm.conf  GRES  merged  with gres.conf contents for this node)
46              and exit.
47
48       -h     Help; print a brief summary of command options.
49
50       -L <file>
51              Write log messages to the specified file.
52
53       -M     Lock slurmd pages into system memory using mlockall (2) to  dis‐
54              able  paging of the slurmd process. This may help in cases where
55              nodes are marked DOWN during periods of heavy swap activity.  If
56              the  mlockall (2) system call is not available, an error will be
57              printed to the log and slurmd will continue as normal.
58
59
60       -n <value>
61              Set the daemon's nice value to the specified value, typically  a
62              negative  number.  Also note the PropagatePrioProcess configura‐
63              tion parameter.
64
65
66       -N <nodename>
67              Run the daemon with the given nodename. Used to emulate a larger
68              system  with more than one slurmd daemon per node. Requires that
69              Slurm be  built  using  the  --enable-multiple-slurmd  configure
70              option.
71
72
73       -v     Verbose operation. Multiple -v's increase verbosity.
74
75       -V, --version
76              Print version information and exit.

ENVIRONMENT VARIABLES

80       The  following  environment  variables can be used to override settings
81       compiled into slurmd.
82
83       SLURM_CONF          The location of the Slurm configuration file.  This
84                           is  overridden by explicitly naming a configuration
85                           file on the command line.
86
87

CORE FILE LOCATION

89       If slurmd is started with the -D option then  the  core  file  will  be
90       written  to  the current working directory.  Otherwise if SlurmdLogFile
91       is a fully qualified path name (starting with a slash), the  core  file
92       will  be  written to the same directory as the log file.  Otherwise the
93       core  file  will  be  written  to  the  SlurmSpoolDir   directory,   or
94       "/var/tmp/"  as  a last resort. If none of the above directories can be
95       written, no core file will be produced.
96
97

NOTES

99       It may be useful to experiment with different slurmd specific  configu‐
100       ration  parameters using a distinct configuration file (e.g. timeouts).
101       However, this special configuration file will not be used by the slurm‐
102       ctld daemon or the Slurm programs, unless you specifically tell each of
103       them to use it. If you desire changing communication ports,  the  loca‐
104       tion  of  the  temporary file system, or other parameters used by other
105       Slurm components, change the common configuration file, slurm.conf.
