问题 I want to seperate thread on the page to prevent freezing of gui. For this, I am running the function which will freeze gui inside another thread with setTimeout but still freezing. The code and jsbin link are below: <!DOCTYPE html> <html> <head> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js" type="text/javascript"></script> <meta charset="utf-8" /> </head> <body> <div id="div1"></div> <div id="div2"></div> <input type="button" value="düðme" id="btn" /> <script

Java Thread - Memory consistency errors

由 点点圈 提交于 2020-11-30 10:32:52
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

Spring batch difference between Multithreading vs partitioning

由 对着背影说爱祢 提交于 2020-11-30 06:47:32
问题 I cannot understand the difference between multi-threading and partitioning in Spring batch. The implementation is of course different: In partitioning you need to prepare the partitions then process it. I want to know what is the difference and which one is more efficient way to process when the bottleneck is the item-processor. 回答1: TL;DR; Neither approach is intended to help when the bottleneck is in the processor. You will see some gains by having multiple items going through a processor

Why is a store-load barrier considered expensive?

由 不打扰是莪最后的温柔 提交于 2020-11-30 06:39:15
问题 Most CPU architectures will re-order stores-load operations, but my question is why? My interpretation of a store-load barrier would look like this: x = 50; store_load_barrier; y = z; Furthermore, I don't see how this barrier would be have much use in lock-free programming in comparison to release and acquire semantics. 回答1: Short Answer : The store-load barrier prevents the processor from speculatively executing LOAD that come after a store-load barrier until all previous stores have

How to use Callable with void return type?

问题 I am working on a project in which I have multiple interface and two Implementations classes which needs to implement these two interfaces. Suppose my first Interface is - public Interface interfaceA { public void abc() throws Exception; } And its implementation is - public class TestA implements interfaceA { // abc method } I am calling it like this - TestA testA = new TestA(); testA.abc(); Now my second interface is - public Interface interfaceB { public void xyz() throws Exception; } And
