DOOM (1)

Deliver a signal to a LAM process.

SYNTAX

    doom [-h] [-<signo>] <nodes> [<processes>]

OPTIONS

    -h

      Print the command help menu.

    -<signo>

      Deliver the signal <signo>.

DESCRIPTION

    Most MPI users will probably not need to use the doom command; see lamclean(1).

    The doom command delivers a signal to one or more processes on one or more nodes. The signal is specified with the -<signo> option. Possible signals are:

    4

      terminate

    5

      suspend execution

    6

      continue execution

    7

      user defined

    8

      user defined

    If a signal is not specified as an option, 4 (terminate) is delivered.

    If no processes are specified, all application processes on that node will receive the signal. Processes can be specified in several ways, a mixture of which may be used on the command line. They are:

    i<index_list>

      by the index printed by state(1)

    p<pid_list>

      by process identifier

EXAMPLES

    doom n0-7 i2

      Terminate all processes with LAM index 2 on nodes 0 through 7.

    doom h p9287-9290

      Terminate local processes with process IDs 9287 through 9290.

    doom -5 n0-7,11

      Suspend execution of all application processes on nodes 0 through 7 and 11.
