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).
This command is only installed if LAM/MPI was configured with the
--with-trillium switch.
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.
