Original Question:I got an array of structs and filling it in a separate thread while reading it in main thread:
To my understanding, Following code should generate 4 clones of the local ProcessingThread running, producing an output:
I have simple code: first thread pushes std::strings to the std::list, and second thread pops std::strings from this std::list. All std::lists operations are protected with std::mutex m. This code permanently prints error to console: "Error: lst.begin() == lst.end()".
I have a strange issue with this code:As I expect because boolean test is not volatile Thread1 uses local cache value of test and when Thread2 changes it to true Thread1 won't do anything. But when I put a breakpoint at the line System.out.println("Prints when put a breakpoint here!"); It...
Do threads blocked by a std::mutex::lock() or a condition variable sleep in a way that frees the core for other processes, or am I required to manually put these threads to sleep? And if true, would std::mutex::try_lock() allow for a way to spin the thread without sleeping?
I have a C# static class accessed from multiple threads. Two questions:Usage of static class from different threads:
If I have an object which is shared between threads, it seems to me that every field should be either final or volatile, with the following reasoning:
I had 2 questions regarding the std::shared_ptr control block:(1) Regarding size: How can I programatically find the exact size of the control block for a std::shared_ptr?
This question already has an answer here:Suppose we have multiple threads and we're dividing the possible keySet between the threads (i.e. key % thread_i) so there's no key collision.
Have a structure declared and defined in shared file.Both threads create by the Windows API CreateThread() have visibility to the instance of it:
