DOOM(1) LAM COMMANDS DOOM(1) NAME doom - Deliver a signal(2,7) to a LAM process. SYNTAX doom [-h] [-<signo>] <nodes> [<processes>] OPTIONS -h Print the command help menu. -<signo> Deliver the signal(2,7) <signo>. DESCRIPTION Most MPI users(1,5) will probably not need to use the doom command; see lam- clean(1). This command is only installed if(3,n) LAM/MPI was configured with the --with-trillium switch. The doom command delivers a signal(2,7) to one or more processes on one or more nodes. The signal(2,7) is specified with the -<signo> option. Possi- ble signals are: 4 terminate 5 suspend execution 6 continue execution 7 user defined 8 user defined If a signal(2,7) 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(1,8) 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.
