Parallel Mono
Recently we announced that Mono achieved full C# 3 support. Along with that comes support for Parallel LINQ. Parallel LINQ, part of Microsoft’s Parallel Extensions library, allows developers to quickly make queries execute across multiple threads.

Bill McCarthy asks “Are Iterators Fundamentally Flawed?”
Iterators are at the core of .NET programming. Only rarely do developers actually work against indexed data, preferring to use for-each loops for most tasks. But is this inherently sequential access method appropriate as we turn more to multi-threaded applications?

Article: Do Java 6 threading optimizations actually work? - Part II
In part 2 of "Java 6 threading optimizations" article series, author Jeroen Borgers examines various threading optimizations and JVM arguments to manage them. He also talks about factors like On Stack Replacement (OSR), Heap Management and Lock object data size which could significantly affect the performance of multi-threaded java applications.

Opinion: Multiple Processor Computing Challenges go Beyond Purely Technical Issues
In his position statement for the International Computer Music Conference 2008, Peter Van Roy raises a number of issues related to the emergence of multi-core processors and loosely coupled systems and suggests possible solutions. Though challenges brought by these two forms of concurrency computing are very different in their nature, both they go beyond purely technical problems.

Coordination Data Structures: New Classes for .NET Multithreading
The June drop of Parallel Extensions for .NET added a set of classes to make sharing data in a multi-threaded application easier. With ten new classes including new synchronization primitives, futures, and new collection classes, there is only time to touch on each of them briefly.

JavaOne: Cliff Click on a Scalable Non-Blocking Coding Style
Dr Cliff Click, a distinguished engineer at Azul Systems, gave a talk at this year's JavaOne about a scalable, non-blocking coding style in Java. The coding style has allowed him to build several lock-free data structures in Java that successfully scale on processors with hundreds of cores.

Should you really learn another language?
Blogger Gustavo Duarte cursed in church when he said that learning new programming languages is often a waste of time. He said that "In reality learning a new language is a gritty business in which most of the effort is spent on low-value tasks with poor return on time invested.". But not everyone agreed.

MPI for .NET
MPI or Message Passing Interface is the standard for distributed programming such as that used in supercomputers and implementations can be found for FORTRAN, C, and C++. There are several projects in the works to bring that power to .NET. Today we look at two of them.
