NAME

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       -h     Help; print a brief summary of command options.
45
46       -L <file>
47              Write log messages to the specified file.
48
49       -M     Lock slurmd pages into system memory using mlockall (2) to  dis‐
50              able  paging of the slurmd process. This may help in cases where
51              nodes are marked DOWN during periods of heavy swap activity.  If
52              the  mlockall (2) system call is not available, an error will be
53              printed to the log and slurmd will continue as normal.
54
55
56       -n <value>
57              Set the daemon's nice value to the specified value, typically  a
58              negative  number.  Also note the PropagatePrioProcess configura‐
59              tion parameter.
60
61
62       -N <hostname>
63              Run the daemon with the given hostname. Used to emulate a larger
64              system  with more than one slurmd daemon per node. Requires that
65              Slurm be  built  using  the  --enable-multiple-slurmd  configure
66              option.
67
68
69       -v     Verbose operation. Multiple -v's increase verbosity.
70
71       -V     Print version information and exit.
72
73

ENVIRONMENT VARIABLES

75       The  following  environment  variables can be used to override settings
76       compiled into slurmd.
77
78       SLURM_CONF          The location of the Slurm configuration file.  This
79                           is  overridden by explicitly naming a configuration
80                           file on the command line.
81
82

CORE FILE LOCATION

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

NOTES

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