New Course Available: Effective Concurrency

Many of you have kindly sent mail about my Effective Concurrency columns and asking when there’ll be a course. Well, I’m happy to announce that the answer is: May 19-21, 2008.

Here’s the brief information (more details below):

3-Day Seminar: Effective Concurrency

May 19-21, 2008
Bellevue, WA, USA
Developed and taught by Herb Sutter

This course covers the fundamental tools that software developers need to write effective concurrent software for both single-core and multi-core/many-core machines. To use concurrency effectively, we must identify and solve four key challenges:

  • Leverage the ability to perform and manage work asynchronously
  • Build applications that naturally run faster on new hardware having more and more cores
  • Manage shared objects in memory effectively to avoid races and deadlocks
  • Engineer specifically for high performance

This seminar will equip attendees to reason correctly about concurrency requirements and tradeoffs, to migrate existing code bases to be concurrency-enabled, and to achieve key success factors for a concurrent programming project. Most code examples in the course can be directly translated to popular platforms and concurrency libraries, including Linux, Windows, Java, .NET, pthreads, and the forthcoming ISO C++0x standard.

Note on class size limit and possible waitlist: There is a hard limit on attendance at this first one (really). But if the registration site says you’ll get waitlisted, don’t give up: Go ahead and sign up anyway because we may be able to put together a second installment of the seminar a week or two later if there’s enough interest.

Finally, here’s a summary of what we’ll cover during the three days.

Fundamentals

  • Define basic concurrency goals and requirements
  • Understand applications’ scalability needs
  • Key concurrency patterns

Isolation: Keep Work Separate

  • Running tasks in isolation and communicate via async messages
  • Integrating multiple messaging systems, including GUIs and sockets
  • Building responsive applications using background workers
  • Threads vs. thread pools

Scalability: Re-enable the Free Lunch

  • When and how to use more cores 
  • Exploiting parallelism in algorithms 
  • Exploiting parallelism in data structures 
  • Breaking the scalability barrier

Consistency: Don’t Corrupt Shared State

  • The many pitfalls of locks–deadlock, convoys, etc.
  • Locking best practices
  • Reducing the need for locking shared data
  • Safe lock-free coding patterns
  • Avoiding the pitfalls of general lock-free coding
  • Races and race-related effects

Migrating Existing Code Bases to Use Concurrency

Near-Future Tools and Features

High Performance Concurrency

  • Machine architecture and concurrency
  • Costs of fundamental operations, including locks, context switches, and system calls
  • Memory and cache effects
  • Data structures that support and undermine concurrency
  • Enabling linear and superlinear scaling

I hope to get to meet some of you here in the Seattle area!

  1. This seminar is awesome, but I find it hard to justify its price at least for some of us who would not be sponsored by our companies to sign up for it :-(
  2. Looks like there’s another one scheduled for September. I’ll have to see if I can get my employer to send me. Looking over the list I see a lot of the same things I’ve been struggling with on my own for the last few months.

    I have been enjoying, and benefiting from your great articles in Dr. Dobb’s Journal!
