DOOM(1) LAM COMMANDS DOOM(1)
doom - Deliver a signal to a LAM process.
doom [-h] [-<signo>] <nodes> [<processes>]
-h Print the command help menu.
-<signo> Deliver the signal <signo>.
Most MPI users will probably not need to use the doom command; see lam-
clean(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. Possi-
ble signals are:
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
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
