Excerpt of article text...

As we've seen the last time, the environment variable already gives us the information about how many logical processing units are available to a given user. (Remember: how many you can use might be restricted by system policies, or perhaps the admin doesn't like you and has decided that four processing units are plenty enough for your unimportant tasks.) So why should we even bother with how many processing units the computer has?

Two reasons.

For one, you can bet that if your app says that you have "four cores available" when the user thinks they should have 72 available, that one or all of the following will happens:

  • the user thinks: "This app gives wrong information. Ditch it and use a better app."

  • a support call to admin ensues who will blame your software instead of taking responsibility

  • a rather irate bug report to you from a frustrated customer
