Here are some links to help you get started with the Microsoft Parallel Extensions to the .Net Framework (PFX).
Starting Out
PFX CTP – Here are the latest CTP bits from June 2008. They come with a whole lot of good examples and good documentation to get you started.
MSDN Parallel Computing Dev Center – Plenty of white papers, videos, podcasts, and articles to get you started.
Channel 9 Back to Basics Series (RSS) – This series is just getting started but looks very promising as a resource for developers new to parallel and concurrent programming. It plans to cover Race Conditions, Deadlocks, Task Granularity, Load Balancing, and Data Locality.
Blogs
Joe Duffy (RSS) – Joe is one of the lead developers for the Parallel Computing Platform, and also just got done writing “The” book for concurrent programming in Windows and .Net. There is a lot of great information here.
Herb Sutter (RSS) – One of the great names in concurrent programming, a little more for the C++ crowd.
PFX Team Blog (RSS) – News and information straight from the horse’s mouth.
Books
Concurrent Programming on Windows, Joe Duffy – This is supposed to be “The” book about programming concurrently in Windows. I have personally bought the “Rough Cut” from Safari and can safely recommend it to anybody trying to learn about concurrent and parallel programming. It is divided into 4 section: Concepts, Mechanisms, Algorithms, and Systems, so there is fun for the whole family.
Videos/Screencasts
Channel 9 Parallel Extensions (RSS) – Great collection for learning all about the Parallel Extensions in and out.
Channel 9 Parallel Computing (RSS) – Focuses more on the whole of the Parallel Computing Platform movement.
I hope these resources can get you started into the world of Parallel/Concurrent programming.
