library hpcsperf
stuck/looping program protection
- start_dead_process_timer
call start_dead_process_timer(value_in_seconds)
sets the maximum value of the allowable interval between calls to i_am_alive - i_am_alive
call i_am_alive
resets the dead process timer
C language example
void main()
{
int timeout=15; /* set timeout to 15 seconds */
useconds_t j=5000000;
start_dead_process_timer(&timeout);
while(1){
fprintf(stderr,"sleeping %d seconds \n",j/1000000);
i_am_alive();
usleep(j);
j=j+3000000;
}
}
FORTRAN language example
program stuck integer timeout integer i timeout=10 call start_dead_process_timer(timeout) do while(1.eq.1) i=i+1 enddo stop end
