Java Multi-thread ~ ~ ~ Non-blocking containers for thread-safe containers

In concurrent programming, the use of containers is often encountered. But if a container is not thread-safe, then the process of inserting or deleting multiple threadsThere will be a variety of problems, is the problem of non-synchronization. So the JDK provides a thread-safe container that allows the container to be securely plugged in multi-threaded situations

Sequential storage containers of QT containers (Introduction)

"""Container containers, which is also called collection, refers to the ability to store other features in memory.Object of a specific type, which is generally a common template class.That is, the QT container class does not have different implementations because of different compilers. The so-called "implicit data sharing" can also be called "copy on write during write ", this technique allows passing value parameters in the container class without a

Java multithreading ~~~ Non-blocking containers of thread-Safe Containers

Java multithreading ~~~ Non-blocking containers of thread-Safe Containers Containers are often used in concurrent programming. However, if a container is not thread-safe, it is inserted or deleted in multiple threads. There will be various problems, that is, the problem of n

Docker combat-storage structure for mirrors and containers

-only, so multiple containers can share the same mirror When you delete a container, Docker daemon deletes the container layer, preserving the mirroring layer 2. Image storage Mode To differentiate the mirroring layer, Docker calculates the UUID for each mirror layer, and before Docker 1.10 generates a random code based on the data in the mirroring layer as the Uuid;docker 1.10 version uses the cryptographi

Java Concurrency (i)--thread-safe containers (top)

The Java thread-safe container consists of two main categories: Vector, Hashtable as well as the wrapper class Collections.synchronizedList and Collections.synchronizedMap ; Java 5.0 introduces a java.util.concurrent package that contains concurrent queues, concurrent HashMap, and copy-on-write containers. According to the author, the early use of the synchronization container has two main

Valid STL thread security features of STL containers

The world of Standard C ++ is quite conservative and streamlined. In this pure world, All executable files are statically linked. No memory ing file or shared memory exists. There is no window system, no network, no database, no process. In this case, you shouldn't be surprised when you find that the standard does not mention anything about the thread. The first idea of STL thread security depends on STL im

Implementation of thread-safe bounded containers in Java

1. IntroductionThis blog describes the use of Wait,notify,notifyall in Java by implementing a bounded container. These keywords use the probability is not high, but read some source code when still often encounter, write to enhance memory.Specific production practices, for me I do not recommend that programmers directly use these, JAVA1.5 after the provision of a lot of directly available thread-safe containers

Develop a data storage container using internal classes to store data containers

Develop a data storage container using internal classes to store data containers Case study: a container is developed to store key-value pairs, English names, Chinese names, and internal classes; Case Design: ① Use static internal classes to encapsulate key-value pairs; ② By default, the container size is 5, which is twice the size of the container if the container size exceeds 5; ③ Call the entryArrays met

[Concurrent parallel]_[c/c++]_[uses thread-local storage threads locally Storage (TLS) calls to copy a file interface case]

Usage scenarios:1. When copying files, it is common for a thread to call an interface to copy files, which requires caching the data, and if each file needs to create a separate cache, the memory fragmentation is large.If you create a static memory area, when multithreading calls the same interface, multiple threads using the same static cache can cause data pollution. The best way is that the cache is visible only to this

[Concurrent parallel]_[c/c++]_[uses thread-local storage for threads locally Storage (TLS)-win32 and pthread comparison]

Scene:1. You need to count the number of objects created on a thread.2. When the heap space is created, it needs to be destroyed based on the thread needs to be created and ended.3. Because the scope is that a thread can only see its own stored data, it does not require a critical section or mutex to maintain its own heap memory. Join if implemented with global S

Boost: thread brief analysis (3): local thread storage and other

There is also an important concept in multi-threaded programming: Thread Local store (TLS, Thread Local Storage). In boost, TLS is also called TSS, thread specific storage.Boost::The thread Library provides us with a simple TLS object-oriented encapsulation interface. The fo

[Concurrent parallel] _ [C/C ++] _ [use a Thread to locally store Thread Local Storage (TLS) to call the copy file interface]

[Concurrent parallel] _ [C/C ++] _ [use a Thread to locally store Thread Local Storage (TLS) to call the copy file interface] Use Cases: 1. When copying a file, a thread generally calls an interface to copy the file. At this time, data needs to be cached. If each file needs to create an independent cache, the memory f

Make a little progress every day-local thread storage in Linux (1)

Reprint please explain the source: When C/C ++ is used in Linux for multi-threaded programming, the most common problem we encounter is the multi-threaded read/write problem of the same variable. In most cases, this type of problem is handled by locking the machine, however, this has a great impact on the program performance. Of course, for data types that the system native supports atomic operations, we can use atomic operations for processin
