critical section

Next to the opening of a short story, the ending is the most critical section.

As a result, two processes can enter the critical section at the same time.

The length of any critical section that needs to be interrupted.

The sampling system is a critical section during flow measurement.

If they are the same, the thread is permitted to enter the critical section.

If own request is at the head of the queue and all replies have been received, enter critical section.

It uses N different levels - each represents another 'waiting room', before the critical section.

This permits the next waiting thread to enter the critical section.

Upon exiting the critical section, send a release message to every process.

In other words we need a way to execute a critical section with mutual exclusion.

After this archaeological digression, we must return to the critical section.

Processes with priority will break from the while loop and enter their critical section.

Note that as in the original paper, the thread checks itself before entering the critical section.

They are designed to avoid requiring a critical section.

This is easy to implement, but sometimes critical sections get uncomfortably long.

The simplest method is to prevent any change of processor control inside the critical section.

Longer critical sections should be divided into small pieces.

Every process maintains a queue of pending requests for entering critical section order.

Operations upon shared states are critical sections that must be mutually exclusive.

A section manipulating shared resources is called a critical section.

One common technique just blocks all interrupts for the duration of the critical section.

In 1913, much of the canal system was abandoned after critical sections were destroyed by flooding.

When a thread wants to enter the critical section, it has to check whether it is its turn to do so.

Entry to a critical section restricts concurrent data structure access.

Processors may have hardware support for some critical sections.
