Discover and Diagnose Java Concurrency Problems Using Contemplate's ThreadSafe
Writing Java software that correctly and safely makes use of concurrency requires careful thought. Software that incorrectly accounts for concurrency can contain intermittent defects that elude even the most rigorous testing regimes. Static analysis tools can analyze source code or compiled bytecode to discover latent bugs hidden within code, long before it is executed.

Inter-thread communications in Java at the speed of light
Developing a light-weight, lockless, inter-thread communication framework in Java without using any locks, synchronizers, semaphores, waits, notifies; and no queues, messages, events or any other concurrency specific words or tools. Just get POJOs communicating behind plain old Java interfaces.

Joe Duffy on Uniqueness and Reference Immutability for Safe Parallelism
We interviewed Joe Duffy, author of Concurrent Programming on Windows, about his research into the use of type systems to ensure safe parallelism. This work was presented in the paper titled Uniqueness and Reference Immutability for Safe Parallelism. We asked for this interview because there seemed to be a lot of misconceptions about this research project.

Designing Next-Generation Massively Multithreaded Architectures for Irregular Applications
In this article, authors discuss Cray XMT, a massively multithreaded architecture framework that addresses the needs of irregular data-intensive applications in emerging fields like bioinformatics, semantic databases, natural language processing, and social network analysis. They also compare this approach with other multithreaded architectures such as GPUs and UltraSPARC processors.

Memory Barriers and JVM Concurrency
Memory barriers, or fences, are a set of processor instructions used to apply ordering limitations on memory operations. This article explains the impact memory barriers have on the determinism of multi-threaded programs. We'll look at how memory barriers relate to JVM concurrency constructs such as volatile, synchronized and atomic conditionals.
