10

OPTIONS

12       -h        Print the command help menu.

DESCRIPTION

17       Most MPI users will probably not need to use the doom command; see lam‐
18       clean(1).  This command is only installed  if  LAM/MPI  was  configured
19       with the --with-trillium switch.
20
21       The  doom  command delivers a signal to one or more processes on one or
22       more nodes.  The signal is specified with the -<signo> option.   Possi‐
23       ble signals are:
24
25       4    terminate
26
27       5    suspend execution
28
29       6    continue execution
30
31       7    user defined
32
33       8    user defined
34
35       If a signal is not specified as an option, 4 (terminate) is delivered.
36
37       If  no  processes are specified, all application processes on that node
38       will receive the signal.  Processes can be specified in several ways, a
39       mixture of which may be used on the command line.  They are:
40
41       i<index_list>   by the index printed by state(1)
42
43       p<pid_list>     by process identifier
44

EXAMPLES

46       doom n0-7 i2
47           Terminate all processes with LAM index 2 on nodes 0 through 7.
48
49       doom h p9287-9290
50           Terminate local processes with process IDs 9287 through 9290.
51
52       doom -5 n0-7,11
53           Suspend execution of all application processes on nodes 0 through 7
54           and 11.
