This is a wrapper I’ve made to make my life easier. Its effect is that the calling thread gets “stuck” to the core with id core_id: // core_id = 0, 1, … n-1, where n is the system’s number of cores int stick_this_thread_to_core(int core_id) { int num_cores = sysconf(_SC_NPROCESSORS_ONLN); if (core_id < 0 || core_id …
Are all (or most) of your requests going to the same host by any chance? There’s a built-in limit on a per-host basis. You can change this in app.config in the system.Net connectionManagement element. The other thing is that the thread pool only ramps up its number of threads gradually – it starts a new …
It’s easier to directly get the CoreWindow from the non-UI thread. The following code will work everywhere, even when GetForCurrentThread() or Window.Current returns null. CoreApplication.MainView.CoreWindow.Dispatcher.RunAsync(CoreDispatcherPriority.Normal, <lambda for your code which should run on the UI thread>); for example: CoreApplication.MainView.CoreWindow.Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () => { // Your UI update code goes here! }); You’ll need to reference Windows.ApplicationModel.Core …
This should do the trick: import requests.adapters session = requests.Session() adapter = requests.adapters.HTTPAdapter(pool_connections=100, pool_maxsize=100) session.mount(‘http://’, adapter) response = session.get(“/mypage”)
In addition to Shamit Verma’s answer: When dealing with debugging multi-threaded Java applications, it is better not to use standard breakpoints that suspend just the thread where the breakpoint is set. Defining a standard breakpoint in your application, will only break the related thread. The other threads will be still running. In eclipse debugger for …
The Apple Concurrency with Core Data documentation is the place to start. Read it really carefully… I was bitten many times by my misunderstandings! Basic rules are: Use one NSPersistentStoreCoordinator per program. You don’t need them per thread. Create one NSManagedObjectContext per thread. Never pass an NSManagedObject on a thread to the other thread. Instead, …
You can’t do this in pure java. But if you really need it — you can use JNI to call native code which do the job. This is the place to start with: http://ovatman.blogspot.com/2010/02/using-java-jni-to-set-thread-affinity.html http://blog.toadhead.net/index.php/2011/01/22/cputhread-affinity-in-java/ UPD: After some thinking, I’ve decided to create my own class for this: ThreadAffinity.java It’s JNA-based, and very simple — …
What is the state of Haskell multi-threading? Mature. The implementation is around 15 years old, with transactional memory for 5 years. GHC is a widely used compiler, with large open source support, and commercial backing. How easy is it to introduce into programs? This depends on the algorithm. Sometimes it can be a one line …
Recently tested if JavaScript running in a iFrame would block JavaScript from running in the parent window. iFrame on same domain as parent: Chrome 68.0.3440.84: Blocks Safari 11.0.2 (13604.4.7.1.3): Blocks Safari 15.1 on iOS: Blocks Firefox 96: Blocks iFrame on different domain as parent Chrome 68.0.3440.84: Doesn’t block Safari 11.0.2 (13604.4.7.1.3): Blocks (outdated, but I …
Java 5+ has all the tools you need for this kind of thing. You will want to: Put all your Producers in one ExecutorService; Put all your Consumers in another ExecutorService; If necessary, communicate between the two using a BlockingQueue. I say “if necessary” for (3) because from my experience it’s an unnecessary step. All …
