Now Pi sets flag[i]=true. It will go past the while loop because turn<>jand the statement in the while loop is false.Pjmay not have finished yet handling the critical section. Impact: with instruction re-ordering both processes can be in the critical section at the same time!
In conclusion, process synchronization is a vital aspect of concurrent computing and operating systems. By employing appropriate synchronization mechanisms, such as mutual exclusion, semaphores, monitors, and condition variables, the order, coordination, and correctness of concurrent processes can be ensured...
The following examples create a publication item named P_SAMPLE11-M. Note:Always drop the publication item in case an item with the same name already exists. The following code creates a publication item P_SAMPLE11-M based on the ORD_MASTER database table and adds it to the publication...
When using locks and memory barriers, you should always give careful thought to their placement in your code. Even locks that seem well placed can actually lull you into a false sense of security. The following series of examples attempt to illustrate this problem by pointing out the flaws in...
These are just a few examples of how automatic synchronization can make managing your data easier, be more timely, and occur at the moment you need it to be uploaded. Synchronization is closely tied to how you define the snapshot for your application. See Section 1.3, "Creating the Publish...

In Part 5, we’ll see more examples of using immutability to simplify multithreading — including PLINQ.It’s also possible to safely assign a new ProgressStatus object based on its preceding value (e.g., it’s possible to “increment” the PercentComplete value) — without locking over more...
