Actors, Messages and Low Lock Contention for Java – Go Parallel

Posted on http://www.ddj.com/go-parallel
Using actors and messages, concurrency is easier to understand. However, most developers don’t want to learn a new programming language in order to use actors and messages. If you want to forget a bit about threads and locks, you can add nice actor support to an existing Java application using Jetlang.

Lightweight Concurrency: Threads are on a Diet – Go Parallel

Posted on http://www.ddj.com/go-parallel
Most modern programming languages are adding lightweight concurrency capabilities. Why is this happening? It is a response to the multicore revolution. You need more parallelism in your applications and you need it without adding a great overhead.

A Domain-Specific Language to Let Groovy Go Parallel

Posted on http://www.ddj.com/go-parallel
Groovy is an agile dynamic language for the Java Platform. It runs on the JVM (Java Virtual Machine). It supports Domain-Specific Languages (DSLs). Last week, GParallelizer 0.7 release added exciting intuitive ways to handle tasks, actors and message. Great news for the Groovy community in order to go parallel.

New Garbage Collectors Designed With Parallelism in Mind

Posted on http://www.ddj.com/go-parallel
On the one hand, Garbage Collectors simplify developers’ lives, but on the other hand, they can become the greatest enemies of a parallelized algorithm’s performance. Finally, Java 7 and .Net 4 are going to offer new Garbage Collectors really targeted for multicore microprocessors with large memories.

Designing Rich Internet Applications With Parallelism in Mind

Posted on www.ddj.com/go-parallel
Are you still designing RIAs (Rich Internet Applications) using a serial programming approach? If that’s the case, then you are losing a big opportunity to achieve a sustainable competitive advantage over competitors.

Counting cores in .Net and Java

Posted on Intel Software Network
As C# and Visual Basic (in the .Net world) and Java are high level programming languages, most developers were not used to check for some hardware information. With multicore microprocessors and a task-oriented programming model, trying to take full advantage of parallel processing capabilities offered by modern microprocessors, this is changing.
