shared-memory

问题 I was reading a Sun's tutorial on Concurrency. But I couldn't understand exactly what memory consistency errors are? I googled about that but didn't find any helpful tutorial or article about that. I know that this question is a subjective one, so you can provide me links to articles on the above topic. It would be great if you explain it with a simple example. 回答1: You can read up about Read After Write (RAW), Write after Write(WAW) and Write After Read (WAR) hazards to learn more about this

问题 What i am trying to do is to make use of global variable by each process. But my process is not taking the global values import multiprocessing count = 0 def smile_detection(thread_name): global count for x in range(10): count +=1 print thread_name,count return count x = multiprocessing.Process(target=smile_detection, args=("Thread1",)) y = multiprocessing.Process(target=smile_detection, args=("Thread2",)) x.start() y.start() I am getting output like Thread1 1 Thread1 2 . . Thread1 9 Thread1

问题 I'm facing a new problem, that occured while coding my IPC for my app. Before UWP I was able to use the directive using System.IO.MemoryMappedFiles; sucessfully. Now I can't use using System.IO.MemoryMappedFiles; and I need it. Is everyone facing the same issue? If yes, how do you solved it? My app doesn't compile anymore. I already tried to reimport the System.Core.dll as a reference and with DllImport, neither worked. 回答1: Direct inter-process communication is not available in Universal

问题 I am using a multiprocessing.Pool which calls a function in 1 or more subprocesses to produce a large chunk of data. The worker process creates a multiprocessing.shared_memory.SharedMemory object and uses the default name assigned by shared_memory . The worker returns the string name of the SharedMemory object to the main process. In the main process the SharedMemory object is linked to, consumed, and then unlinked & closed . At shutdown I'm seeing warnings from resource_tracker : /usr/local
