Descriptions

The process scheduler in the Linux kernel 2.4 performs scheduling based on CPU billing gathered from periodic process sampling ticks, which allows local users to cause a denial of service (CPU consumption) by performing voluntary nanosecond sleeps that result in the process not being active during a clock interrupt, as described in "Secretly Monopolizing the CPU Without Superuser Privileges."

El planificador de procesos en Linux kernel 2.4 realiza planificación basado en la facturación CPU, recolectada con ticks de muestreo periódico de proceso, lo cual permite a usuarios locales provocar una denegación de servicio (agotamiento de CPU) realizando pausas voluntarias de nanosegundos que resultan en que el proceso no se encuentre activo durante una interrupción de reloj, como se describe en "Monopolizando secretamente la CPU sin privilegios de super-usuario"
