Deadlocks
Deadlock is a situation where processes are in a state of being unable to continue working, because each process has locked up a resource that a second process also requires. This creates an unending loop of waiting during which the processes cannot be executed (Mutual Exclusion). To avoid this problem, the operating system must have a method for detecting deadlocks. It must also be able resolve them when they happen.
A common method of avoiding deadlocks is to assign resources to a single category. A system could for instance, divide resources into categories such as memory, printers and CPUs. This allows all processes to access the same resources, without causing deadlocks.
This method can be employed together with a Banker's algorithm for detecting deadlocks. This method checks the status of each process, and in the event that they haven't completed their task, it's believed that the process is stuck in a deadlock. However this method isn't foolproof. A programmer could still create deadlocks that the operating system could not recognize.
Another way to prevent deadlocks is to make sure that all processes hold and let their own resources go before making requests for new ones. This allows operating systems to anticipate requests for processes and free up resources. This prevents starvation however it has its drawbacks such as a late start of the process and frequent preemptions.
Another method is to use a deadlock detection method which makes use of a queue in order to track the state of each process and its children. This kind of system is useful for finding deadlocks that cannot be identified by a simple test. It is only possible to use when operating systems are designed to accommodate this kind of fix.
Priority queues are another method to prevent deadlocks. Each process is assigned a numerical priority. The higher priority of a process is, the more likely it will be the victim of rolling back. This method is good for reducing the number deadlocks, but it can result in low-priority processes being postponed indefinitely. This is the reason why it's not recommended for tasks with high priority.
