Visual Studio 2010 Parallel Development Overview

Parallel Development

As demands for application performance increased, customers

have traditionally solved the problem by simply increasing the

underlying power of the hardware that the application is running

on. Over the last several years developers have seen the CPUs

that their applications run on start to include 2, 4 or more cores.

While the power of the hardware has increased, the transition

to a multi-core environment has impacted the applications that

developers write. The majority of applications will not be able to

automatically take advantage of this multi-core hardware change.

Developers will need to modify the way they write applications

and the architectures they use for these applications.

Creating parallel capable code using current technologies is

unfortunately not trivial. Multi-thread programming introduces

not only application architecture challenges to complexity and

robustness but also exposes the tooling developers use as being

optimized for single-threaded development.

Microsoft is making a major commitment to make parallel

development accessible to a wide range of developers, whether

they are using native code or the .NET Framework. With Visual

Studio 2010 we are delivering:

• Visual Studio IDE support for Parallel development

• Native C++ libraries and compiler support

for Parallel applications

The .NET Framework 4.0 also provides the core framework

support to build parallel applications through technologies such

as P-LIINQ and parallel language semantics and framework

components. Visual Studio 2010 provides integrated parallel

development support. In Visual Studio 2010 the debugger is

aware of the parallel nature of code and can present the state of

the application execution during debugging across the different

parallel execution units. The debugger also has custom displays

for parallel code such as task & thread windows and a “multi” or

“cactus” stack view window that graphically shows the execution

path of the individual tasks.

Being able to develop and debug your application doesn’t

mean that it takes advantage of all the available power. To

help developers do this, Visual Studio 2010 also includes

a parallel capable performance analyzer that enables you

to extensively instrument you code to visually see the

concurrency issues that are in your applications. Combine

this with the features of the Visual Studio IDE, and developers

have a highly productive, visual environment for building the

best parallel capable applications available.
