　　软件是 运行在硬件之上的。当硬件发展了，软件也要做相应的变化，才能跟上时代的步伐。面对多核时代的到来，软件世界的并行计算开始兴盛起来。如何更加充分地利用 CPU的多个核心?如何发挥多核的威力，带来软件性能上的提升?如何改造现有的程序，让她更好地适应多核时代?如何简便地实现并行计算，使自己开发的应用 程序充分地利用硬件升级所带来的性能提升?这些问题，无不困扰着我们这些多核时代的程序员们。

　　现在崭新的Visual Studio 2010为我们带来了完整的并行计算解决方案，让我们可以从容面对多核时代的到来。

　　天下不再有“免费的午餐”

　 　在以往的计算机发展历史中，硬件技术的发展，特别是CPU频率的不断提高，总是给软件带来免费的性能提升。从386到586，从赛扬到奔腾，每次CPU 频率的提升，都带来软件性能的大幅提升，而软件无需做任何变动。如果有客户抱怨你的软件性能不佳，我们无需着急，只需要坐等Intel或者AMD推出更高 频率的CPU就可以了。程序员们把这形象地称为“免费的午餐”。

图1，多核时代

　 　当单核CPU的频率发展到3G之后，再往上发展就遇到了技术瓶颈，单核心CPU的发展已经到达一个极限，硬件厂商不得不转而向多核芯CPU发展，在一颗 芯片中加入两个甚至多个运算核心，通过核心的增加，来提高芯片总的频率。虽然在硬件厂商看来，这仿佛是一个创举，但是却给软件厂商带来了无尽的烦劳。程序 员们发现，进入多核时代后，这种“免费的午餐”再也没有了。这其中最主要的原因就是当前的应用程序几乎都是针对一个运算核心而设计的，当硬件通过增加运算 核心来提高性能时，由于受到其架构的影响，软件并不能充分地利于多个运算核心所带来的性能提升，甚至有的时候性能还有所下降。在这种情况下，开发者不得不 改变应用程序的架构和开发方法，以应对这种多核的趋势，使得自己的软件可以充分利于硬件升级所带来的性能提升。开发者希望有一个工具能够帮助他们分析应用 程序中的性能瓶颈，能够简便地将现有的业务逻辑并行化处理，从而更好地利用硬件，提升软件的性能。面对这样的需求，作为下一代开发平台，Visual Studio 2010加大了对并行运算的支持。微软正在使得尽量大的范围内的开发者都能高效而简便地进行并行计算的开发，不管他使用的是非托管代码还是.NET Framework。从而将开发者从繁琐而复杂的多线程开发中解放出来，将更多的精力放到业务逻辑上。在Visual Studio 2010中，我们将看到：

　　• Visual Studio IDE对并行计算开发的大量支持。比如，Visual Studio 2010的调试器知道代码的并行特性，并且能够在调试程序的不同执行单元的时候，表现应用程序的状态。

　　• 非托管的C++库和编译器对并行计算的支持

　　• .NET Framework 4.0对并行计算的大量支持，包括PLINQ、并行语言语句等等

　 　另外，Visual Studio 2010还提供了一个“并行性能分析器”，它可以帮助我们分析应用程序的性能瓶颈，找到需要并行处理和可以进行并行处理的地方，并以图形化的形式表现出 来。这样，“并行性能分析器”配合着Visual Studio 2010，我们就可以轻松地实现应用程序的并行化。

核心提示：对于MSDN订阅用户，今天可以获得Beta2，其他用户10月21日可以获得beta2.

微软同时宣布，将于2010年3月22日正式发布Visual Studio 2010.

Microsoft has struggled with the best way to sell Visual Studio's application lifecycle management ever since it introduced Team System against IBM's Rational four years back. As the company prepares to release Visual Studio 2010 for Windows 7, Office 2010 and a new line Windows servers about to come on tap, Microsoft is taking another stab.

This time, the company is spicing the packaging mix by throwing in hours of access to its Azure cloud plus upgrades to a new, top-of-the-line Visual Studio ALM package.

The changes will be unveiled today, as Microsoft announces the second Visual Studio 2010 beta and .NET Framework 4 beta two have been released to MSDN subscribers with everyone else getting code on October 21.

Also, Microsoft will announce Visual Studio 2010 will officially launch on March 22, 2010.

Visual Studio 2010 and.NET Framework 4 have been promised as "the most significant release" Microsoft's had of the tools suite and framework "in a number of years."

Microsoft says this about all products, but we assume this time it's referring to Visual Studio 2005 and Team System 2005 that debuted Microsoft's ALM push and came before Visual Studio 2008.

New features include Windows 7 and SharePoint 2010 tools, drag-and-drop bindings with Silverlight and Windows Presentation Foundation, the inclusion of the Dynamic Language Runtime (DLR) for programming with scripting languages, and support for parallel programming.

It's the packaging mix that sees the most change, though.

Microsoft will chop nine Visual Studio SKUs down to four, with the focus on ALM. Microsoft does not seem to be tampering with the Express editions, which add another five SKUs.

Visual Studio Development Edition, Database Edition, Architect Edition and Test Edition will go. These will give way to Visual Studio 2010 Professional priced $799 and no MSDN subscription option, Professional priced $1,199 for a new MSDN subscription, Premium priced $5,469 for a new MSDN subscription, and the new completely Ultimate Visual Studio SKU that will be priced $11,924 for a new MSDN subscription.

You can compare these MSDN subscription prices with those for Visual Studio 2008, here.

Senior director of developer marketing Dave Mendlen said Microsoft is cutting the number of Visual Studio SKUs following customer feedback. Mendlen said the new packages reflect the way developers work, by combining code, test, architect and collaborate options. This is a reversal, as the previous philosophy was separate Visual Studios for separate roles.

What do you get in your new packages?

Visual Studio 2010 Professional minus the MSDN subscription will feature core developer features, the integrated development environment, platform support and parallel debugging. With the MSDN sub, you'll actually get the current and previous client and server operating system runtimes.

Premium will include code analysis, database deployment, user interface testing and test impact analysis. The addition of the MSDN sub will give you the server platforms for Dynamics, SharePoint and Exchange, plus Office, Expression and some Team Foundation Server features.

Ultimate will include all these features, plus UML tools, historical debugging, manual testing products and load testing along with the full Visual Studio 2010 Team Foundation Server.

Microsoft will chuck Azure cloud compute time, storage and data transfer into the MSDN Premium subscription. Developers will get 750 computing hours per month for eight months - time that will commence once Azure becomes commercially available, expected next month.

The company will also try to upsell you under it's so-called Ultimate offer. Developers on the soon-to-be canned Visual Studio 2008 Team System editions or on Visual Studio 2008 who splash out and upgrade to the Professional-level MSDN subscription before March 22 will get Ultimate at no cost when it ships. Those on Visual Studio 2008 Professional and MSDN Professional now will get Visual Studio 2010 Premium at no extra cost.
