DOOM(1)

NAME
doom - 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.
