Cancellation
Discussion of thread cancellation techniques in Java. (excerpt from Doug Lea's Concurrent Programming in Java book)
The "Double-Checked Locking is Broken" Declaration
Details on the reasons - some very subtle - why double-checked locking cannot be relied upon to be safe. Signed by a number of experts, including Sun engineers.
Implementing Read-Write Locks in Java
Read-write locks allow multiple threads to acquire a read lock provided no other thread currently has a write lock on the same object. A thread can acquire a write lock if no other thread owns either a read lock or a write lock.
Java Technology, Threads, and Scheduling in Linux
Examines the performance of the Linux kernel when the system is running a heavily threaded Java program using the IBM Java Developer Kit for Linux.
mdthread
Message Driven Thread API for Java, which enables deadlock safe, multithreaded, concurrent, high level communication between threads.
Multi-Threading -- The Next Level
By Edward Harned. This article takes the multi-threading structures available today to the next level by making professional quality, Open Source code available to all programmers.
Multi-threading in Java
Article by Neel V. Kumar. A tour in the land of multithreading in Java. Introduces the mechanisms and demonstrates how to use them in limited but very common cases.
A Proposal for Fixing the Java Programming Language's Threading Problems
Java's threading model is entirely inadequate for programs of realistic complexity and isn't in the least bit object oriented.
Seminar: Concurrent Programming in Java
A comprehensive course covering all aspects of multi-thread programming in Java from plain synchronization over Java 5.0 concurrency utilities to memory model issues.
Simple Java Thread Management Library (SJT.Mgmt)
An easy to use library for adding thread management in Java applications. The library comes from early experience with JServ's lack of thread management, and recent posts to the java developer forums. [Open source]
Thread Synchronization in Java
Producer Consumer, Dining Philosophers, Reader Writer problems. Applet demonstration, design diagram. Source code accessable by e-mail request.
Thread Synchronization in Java (Sources)
Introduces basic concurrency problems and shows how to solve them by using builtin Java synchronization primitives. (Only sources free accessed without registration)
Threading Lightly: Exploiting ThreadLocal to Enhance Scalability
Examines ThreadLocal and offers tips for exploiting its power.
Threading Lightly: Reducing Contention
Explains why contended synchronization is a problem and then explores several techniques for reducing contention, and hence improving scalability.
Threading Lightly: Synchronization is not the Enemy
Takes a look at the semantics and the performance penalty of Java's synchronized keyword.
Writing Multithreaded Java Applications
Introduces the Java Thread API, outlines issues involved in multithreading, and offers solutions to common problems.
A Critique of Java for Concurrent Programming
Presents some predictions of how concurrent programming might evolve during until 2015. (September, 2005)
Going Atomic
Explains how the new atomic variable classes in JDK 5.0 enable the development of highly scalable nonblocking algorithms in the Java language. (November 23, 2004)
Hey, where'd my thread go?
If you're not careful, threads can disappear from server applications without a (stack) trace. In this article, threading expert Brian Goetz offers some techniques for both prevention and detection of threads going AWOL. (September, 2002)
Achieve Strong Performance With Threads, Part 4
Focuses on thread groups, volatility, thread-local variables, timers, and the ThreadDeath class. Also describes how various thread concepts combine to finalize objects. (August, 2002)
