NAME

doom - Deliver a signal to a LAM process.

SYNOPSIS

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:

iindex_list
by the index printed by state(1)
ppid_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.
