Do NOT run this unless you are prepared to reboot. :-(

When I ran the code below....

test.sh 5
Max runtime exceeded, killing PID 2749
/home/andy/bin/test.sh: line 30: 2749 Killed $command > /dev/null 2> /dev/null
Killed.

Code:

command="/usr/bin/stress --cpu 8 --io 4 --vm 2 --vm-bytes 128M"

maxruntime=$1

$command >/dev/null 2>/dev/null &
watchpid=$!

/bin/sleep "$maxruntime"

if [ -d "/proc/$watchpid" ]
then
        echo "Max runtime exceeded, killing PID $watchpid"

        if /bin/kill -9 "$watchpid" >/dev/null 2>/dev/null
        then
                echo "Killed."
                exit 0
        else
                echo "Could not kill, please investigate manually."
                exit 1
        fi
fi

If you are gonna slice haberno peppers, either use gloves or wash hands 3 times. I forgot and rubbed my eyes.

NAME

     cpuset_create, cpuset_destroy, cpuset_zero, cpuset_set, cpuset_clr, cpuset_isset, cpuset_size -- dynamic CPU sets

SYNOPSIS

     #include <sched.h>

     cpuset_t *
     cpuset_create(void);

     void
     cpuset_destroy(cpuset_t *set);

     void
     cpuset_zero(cpuset_t *set);

     int
     cpuset_set(cpuid_t cpu, cpuset_t *set);

     int
     cpuset_clr(cpuid_t cpu, cpuset_t *set);

     int
     cpuset_isset(cpuid_t cpu, const cpuset_t *set);

     size_t
     cpuset_size(const cpuset_t *set);

DESCRIPTION

     This section describes the functions used to create, set, use and destroy the dynamic CPU sets.

     This API can be used with the POSIX threads, see pthread(3) and affinity(3).

     The ID of the primary CPU in the system is 0.

FUNCTIONS

     cpuset_create()
	      Allocates and initializes a clean CPU-set.  Returns the pointer to the CPU-set, or NULL on failure.

     cpuset_destroy(set)
	      Destroy the CPU-set specified by set.

     cpuset_zero(set)
	      Makes the CPU-set specified by set clean, that is, memory is initialized to zero bytes, and none of the CPUs set.

     cpuset_set(cpu, set)
	      Sets the CPU specified by cpu in set.  Returns zero on success, and -1 if cpu is invalid.

     cpuset_clr(cpu, set)
	      Clears the CPU specified by cpu in the CPU-set set.  Returns zero on success, and -1 if cpu is invalid.

     cpuset_isset(cpu, set)
	      Checks if CPU specified by cpu is set in the CPU-set set.  Returns the positive number if set, zero if not set, and -1 if cpu is
	      invalid.

     cpuset_size(set)
	      Returns the size in bytes of CPU-set specified by set.

SEE ALSO

     affinity(3), pset(3), sched(3), schedctl(8), kcpuset(9)

HISTORY

     The dynamic CPU sets appeared in NetBSD 5.0.
