15 Top Java multithreaded questions and answers http://ifeve.com/15-java-faq/1, about the state of the thread and mutual conversion(1) Join () method: Enables the thread to execute sequentially. You can divide a task into subtasks, call the Join () method, wait for those subtasks to complete the operation, and then summarize the results. It is important to note that this does not guarantee the end order of

Tag: Pos directly executes www htm operation desc via scheduleHttp://www.cs.umd.edu/projects/shop/description.htmlIn HTN planning, planning the system from the initial state of the world and creating a plan to perform a series of tasks (things that need to be done, abstract). By reducing the HTN planning problem: Planning recursive decomposition into subtasks tasks, when stopped, can be directly carried out by the operator of the original task plannin

finally converge the small tasks to get results. It is very similar to the MapReduce framework provided by Hadoop, but the task of MapReduce can take full advantage of the ability of the cluster to complete computing tasks for all compute nodes within the cluster. Forkjoin is more akin to a standalone version of MapReduce.Even if it is not through MapReduce, only the application itself can be decomposed and synthesized tasks, but from the implementation of the difficulty to consider, their own

The core idea of the Master-worker model is that the system works in collaboration with two types of processes: Master and worker processes. The master process is responsible for receiving and assigning tasks, and the worker process is responsible for processing subtasks. When the worker process finishes processing the individual subtasks, the results are returned to the master process, which is summarized

Processes and Threads:* Process: A process is a basic unit of program execution and resource allocation in a system, each with its own data segments (stored data), code snippets (stored code), stack segments (objects and variables). # resources such as global variables cannot be shared across multiple processes, and modifying global variables in a child process has no effect on global variables in the parent process.* Threads: In a process to do multiple tasks at the same time, you have to run m

if all the tasks are executing at the same time.True parallel multitasking can only be done on multicore CPUs, but because the number of tasks is much larger than the number of cores in the CPU, the operating system automatically shifts many tasks to each core.For the operating system, a task is a process, such as open a browser is to start a browser process, open a notepad started a Notepad process, open two Notepad started the two Notepad process, open a word started a word process.Some proce

Threads ProcessesFor the operating system, a task is a process, such as open a browser is to start a browser process, open a notepad started a Notepad process, open two Notepad started the two Notepad process, open a wordA word process is started. A process is a collection of many resources.Some processes do more than one thing at the same time, such as word, which can be typed, spell-checked, and printed at the same time. Within a process, to do multiple tasks at the same time, you need to run

Since the initial Java 2 platform, Version 1.2 has been released, the Java collections Framework has been evolving. In Java SE 5, the introduction of generics enhances the framework, and the introduction of java.util.concurrent adds direct support for concurrency (see Resources). In Java SE 6, a better bidirectional collection access feature is added to the framework. This article will introduce you to all of these aspects of the collection library and help you take advantage of the popular feat

, development may come to you for discussion, may be too lazy to spend time to communicate directly in accordance with their own understanding to achieve. Finally, the acceptance test is not working well, and you can't rely on development. So try to write the interactive document in a comprehensive way, and do not consume the value of your trust from the development colleague. So what do you need to write in an interactive document? 1, page flow (between the interface) The page flowchart can

on the logic of the program to determine which subtasks are asynchronous, those subtasks are synchronous.2. Classification of threads2.1 User-level threads: The initial operating system is not thread-support, but for the user's needs, but not in a short period of time to modify the operating system kernel implementation thread in the kernel, so only first in the userThreads are implemented through line lib

greatly improved. Although the development of the process solves the concurrency problem of the operating system, people are still not satisfied, people gradually have a demand for real-time. Because a process can only do one thing in a period of time, if a process has more than one subtask, you can only perform these subtasks on a per-task basis. For example, for a monitoring system, it not only to display the image data on the screen, but also to c

multitasking can only be done on multicore CPUs, but because the number of tasks is much larger than the number of cores in the CPU, the operating system automatically shifts many tasks to each core.For the operating system, a task is a process, such as open a browser is to start a browser process, open a notepad started a Notepad process, open two Notepad started the two Notepad process, open a word started a word process.Some processes do more than one thing at the same time, such as word, wh

myrunnable (); Thread thread = new Thread (runnable); Thread.Start (); } Class Myrunnable implements runnable{public myrunnable () { } @Override public void Run () { SYSTEM.OUT.PRINTLN ("Child thread ID:" +thread.currentthread (). GetId ()); } Runnable's Chinese meaning is "task", as the name suggests, by implementing the Runnable interface, we define a subtask and then leave the subtasks to thread to execute. Note that this m

Rake, I'm not going to introduce Ruby's make, in many ways, much better than made. Unlike Makefile, the Rakefile itself is a piece of ruby code, and there's a lot of benefits in it where you can do whatever Ruby can do directly in Rake, and because Ruby is good for DSL, Rakefile usually It doesn't look that "code" either. However, the code is always code, Makefile can write a very messy, rakefile to write chaos is easier, fortunately, Rake provides some features so that we can come to the Rakef

In small program development, the use of promise can significantly reduce the code, improve the simplicity of the code. The following article from the blog Park Lu Tai Leopard vernacular explain promise, the article written very well, concise and understandable, it is worth reading. The transcript is reproduced here, with a slight partial deletion. This library is in the browser and is common in small programs. There are four main uses: use then to implement chained calls: sequentially complete

The core architecture of Informix dynamic servers is designed to provide built-in multiple threads and parallel processing capabilities. Multiple clues In the database server, the Informix dynamic server uses an adjustable database server process pool called a ' virtual processor ', which is used to plan and manage the user's request. User requests are expressed through a lightweight mechanism called ' clues ', a single, coherent flow of control that expresses an independent task in the databa
