About Me
• Microsoft MVP• Intel Blogger• TechEd Israel, TechEd Europe• Expert C++ Book
• http://AsyncOp.com• http://Asaf.Shelly.co.il
Task Parallel Library - TPL
• .Net Framework 3.5• See TechEd 2008• VS2010 with .Net 4.0• Language Extensions• Lambda Expressions• C#, VB, F#, C++
From for to Parallel.For
for (int i=0; i<100; i++){ int x = i + i;}
Parallel.For(0, 100, i =>{ int x = i + i;});
C++ parallel_for
parallel_for(0, 100, [&] i{ int x = i + i;});
Visual Studio 2010
• Multi-Core Programming• Tasks• Agents• Parallel Loops• Parallel Algorithms• Parallel Replacement for STL• Seamless Task Usage
Task Oriented Design

PLINQ – Parallel LINQ
VS2010 DemoC# Parallel.For
Keep an eye for…
• Shared are Globals• Parallel Loops are not loops• Define data as Loop internal• Race Conditions are still here• Locks!!• I/O – Disk, Network, etc.

Change In MindsetEverything is stopped. Waiting for the photographer
Everyone is working independently
Change In MindsetDevelopers are writing functions
Developers are managing tasks
Change In MindsetDoing things the way we always have
Things are going to be different
