The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Determine physical CPU count for a computer using C#

Asked by jmiller47 in C# Programming Language

Tags: count, cpu

I am writing a simple asset management application to collect information about remote computers and store the information in a database for reporting. I am mostly using WMI to collect the information.

The issue I am having is that no matter how I try to collect the CPU count, I get back incorrect information. Because of the introduction of Hyperthreading and Dual Core CPUs, the CPU counts show double or even quadruple CPU counts. For example, if a computer has 2 physical CPUs and have hyperthreading enabled, the CPU count will show as 4 CPUs. If the same computer is using Dual Core CPUs with Hyperthreading enabled, the CPU count will be 8. This is the number shown anywhere you look in the operating system is also skewed by dual core and hyperthreaded CPUs.

Does anyone have any idea of a way I can determine the real physical CPU count?

Thanks in adavance!
