Mike Ash's Friday Q&A's on GCD should be of great use. You may have noticed that up to this point I have only talked about concurrency. You can also pass another value for 'concurrency' if you'd like to test more devices at a time. In this post, I'd like to demonstrate how the Visual Studio Concurrency Visualizer can be used to efficiently identify MPI communication overheads on the Windows HPC Server platform. The ramifications of this is that special attention needs to be paid to the reporting function with regard to concurrency. The Java API provides two ways to enable this communication. So we want a thread object to be able to tell us something, but how do we go about structuring that communication? Communication between threads occurs implicitly, through modification of shared memory locations. More specifically the communication between processes in concurrent languages. I received a recent comment asking how to . The two may be able to communicate with each other (via postMessage ), but message passing has no concurrency problems, since you're just sending copies of data around. This is the fourth part of the tutorial, and this link goes to the previous post java concurrency part 3. Scripting SA Communication Tests in 7.86. No threading issues in JavaScript. And condition variables for concurrency control. Neither can run until the other gives up its lock, so they will wait forever or blocked Threads can communicate to other threads about their status of an event. Answer: Three ways by which you can handle concurrency in WCF is Single, multiple and reentrant. Deadlock happen when two threads are blocked waiting for an object's lock that each thread posses. Many people are incredulous when I tell them this, because it immediately conjures in their mind the myriad complexities of concurrency: locks, monitors, deadlock, dining philosophers, …. Examples include C's pthreads API, and Java and .NET's built-in threading support. For most applications, the speed of light is embarassingly adequate, but roundtrip communication around the globe faces real communication issues, such as propagation delay, and therefore communication protocol design becomes the dominating factor in performance. I've chosen Objective-C for the second part of Joe's challenge, hopefully leveraging Grand Central Dispatch for concurrency.
