Wherein, new process has five states in linux operating system: TASK_RUNNING, TASK_INTERRUPTIBEL, TASK_UNINTERRUPTIBLE, TASK_STOPPED and TASK_ZOMBILE; TASK_INTERRUPTIBLE, TASK_UNINTERRUPTIBLE, TASK_STOPPED and TASK_ZOMBIE are non-TASK_RUNNING state.
The prioritization scheme of the process scheduling of a set of linux operating system of the method design and implimentation, realizing operating system can according to actual needs, more, obtain bottom physical resource faster.Mainly according to the actual needs of current system, write a set of automatized script, in the parameter that os starting run duration imports into according to automatized script, the different scheduling strategies of calling process.By automatized script, user can regulating parameter, is regulated the scheduling strategy of the process of linux kernel by parameter.And, user can according to the needs of oneself, strategy and the runlevel of the scheduling of started the machine watch-dog are set, make it according to operation need occupy concurrent physical processor, such as the task of real-time, the scheduling strategy of real-time process can be set to, select SCHED_FIFO scheduling strategy or SCHED_RR scheduling strategy, for non real-time common task, select the SCHED_FIFO scheduling strategy of acquiescence, intensive for operation, response time requirement is low, the batch processing task that interactivity is not strong, can select SCHED_BATCH scheduling strategy.
Detailed, in an operating system, it is realized by different system call functions that user's space and kernel spacing create a new process.Create a new process by the system call of fork family of functions at user's space, as fork (), clone (), vfork () function, at kernel spacing by calling kernel_thread () function to create a kernel process.In the process creating new process, determined the attribute of process resource requirement by different option parameter, as CLONE_FILES, CLONE_SIGHAND parameter represents that subprocess and parent process are shared identical filec descriptor and closed signal transacting table respectively.Because calling process is in TASK_RUNNING state, then subprocess acquiescence is also in TASK_STOPPED state.With CLONE_STOPPED option, then the original state of subprocess will be TASK_STOPPED state.
Wherein, in (SuSE) Linux OS, process has five states in systems in which: TASK_RUNNING, TASK_INTERRUPTIBEL, TASK_UNINTERRUPTIBLE, TASK_STOPPED and TASK_ZOMBILE.TASK_RUNNING represents process just in running status, process can carry out actual operation, TASK_INTERRUPTIBLE represents it is the process be in waiting list, can be waken up by signal interruption, TASK_UNINTERRUPTIBLE represents can not interrupt latency state, also be the process be in waiting list, but cannot be slept by signal interruption by other processes, TASK_STOPPED represents halted state, process is suspended, TASK_ZOMBILE represents ossified state, procedure termination, be the transition state that process terminates to run.
Wherein, the process of (SuSE) Linux OS from establishment, run to final cycle and terminate to exit, a series of change can be there is in state of a process.But from occupying angle to cpu resource, only have TASK_RUNNING state and non-TASK_RUNNING state two states, namely TASK_INTERRUPTIBLE, TASK_UNINTERRUPTIBLE, TASK_STOPPED, TASK_ZOMBIE can be summarized as non-TASK_RUNNING state.Conversion between process status just can regard the conversion between TASK_RUNNING state and non-TASK_RUNNING state as.
Wherein, when the operating system process being in TASK_INTERRUPTIBLE state receives SIGKILL signal, operating system process status can first change TASK_RUNNING state into, then SIGKILL signal is responded, change TASK_DEAD state into, and can not directly exit from TASK_INTERRUPTIBLE state; When the I/O simulated operation that operating system process is waited for realizes, needs are TASK_RUNNING state from non-TASK_RUNNING state transfer, at this moment operating system state of a process is made to be converted to TASK_RUNNING state, and the queue of operating system process is joined CPU can operation queue, make operating system process have an opportunity to be dispatched when next scheduling occasion arrives.
