Overview
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. |
