As we saw in the previous sections, the implementation of multiprocessing requires more than one processing unit. The processing units (hardware) and the operating system (software) are the main enablers of multiprocessing and multithreading. Technical Details of Multiprocessing and Multithreading So, these multiple threads must share the time of the processing units and usually don’t execute all the time at the same time. The editor’s graphical interface is a thread there is another thread to catch the letters typed by the users another to save the document and probably others that we don’t realize just using the editor. Let’s take the text editor as an example. Observing our programs (processes), we can note that they generally execute multiple tasks concurrently. In this case, the processes share the processing time of these units. However, in fact, we execute much more processes than the available processing units. So, for example, we can run, at the same time, a web browser and text editor. Currently, modern personal computers typically have two or more processing units, which allows multiprocessing. We can analyze multiprocessing and multithreading with concrete examples. However, the processing time of a processing unit must be assigned to the running threads according to a specific strategy. So, multithreading does not require multiple physical processing units, as multiprocessing does. In practice, multithreading occurs when at least one process with multiple threads executes in a computer system. Multithreading refers to the possibility of executing heterogeneous tasks of a particular process concurrently.In this way, different processes can execute at the same time. It is relevant to note that multiprocessing systems demand multiple physical processing units in the computer system. ![]() Multiprocessing refers to the possibility of simultaneous execution of more than one process in a computer system.Since processes are isolated programs, data exchanging between them relies on inter-process communication mechanisms. Cooperating processes, in turn, exchange data with other processes during their execution. Independent processes don’t communicate with other processes and aren’t affected by them. Regarding communication, processes are categorized as independent or cooperating. However, all the threads of the same process share the process’ code and data sections. These resources are particular to each thread. In technical terms, threads demand similar resources to a process, such as a memory stack, program counter, and set of registers. Specifically, a thread executes a task in the context of a process. Threads are lightweight semi-processes that depend on a process. In other words, a particular computer process does not directly interfere neither in the code execution nor in the data resources of another process. Hence, computer processes have their own isolated sections of code and data. My mac mini is slow as you know.In general, we can see processes as instances of programs that execute in a computer system. So even if I throw $2500 on a basic level trashcan I have the whole Encoder and DnX issue. there are issues there i don't need to get into now. YES I have looked into the few "non-official" ProREs makers. But trust me I've talked to them and they confirm it is an issue. BUT has a issue with more then 4ch out ProResHQ. Yes I can put it into Premiere and then throw a "levels" EFX and tweak that then export. So I can't just throw it into encoder on a MAC and set it up. Adobe/Premiere/Media encoder/Fusion don't read DnX levels right. Taking that file and making a Legitimate ProResHQ file. Now the tricky part, you know where I'm going with this. As far as I know this is the only way from Avid to export multi audio tracks. This let's me do a Same As Source (175x) and also let's me set audio to DirectOut. So workflow has been in Avid to do a Mixdown to 175x and have the audio tracks needed at it's own Seq. Many of my deliverables need 6 or even 10 tracks audio. Like a lot you guys I have moved to PC few years ago. Doing it on Resolve, Avid Symphony, Premiere. ![]()
