Troubleshooting and Improving Performance

During Spring 2012, CPUsage rolled out a major update to Cirrus, our partner software for Windows machines. Cirrus is the lightweight tool that allows CPUsage to harness your unused processing power, in turn earning you points. If you are running this software and are experiencing any issues or are not earning as many points as expected, please review the tips and tricks below.

General Troubleshooting (Windows)

  • Is Cirrus running?
    • Look for a circular icon with an arrow in your system tray (lower right corner of the screen).
    • If no, go to Start>Programs>Cirrus and launch the application.
  • Are you logged in to Cirrus?
    • If you found our logo in your system tray, check to see if the arrow is orange. If it is all gray, you are not logged in.
    • Login with the same email address and password you used when signing up with CPUsage online.
  • Does your computer meet the minimum system requirements?
    • Cirrus requires a minimum of 1.5gb of RAM. At least 2gb is recommended.
    • Your processor should be a minimum of 1.6Ghz.
    • Cirrus can struggle on older machines, with CPU’s made before 2005.
  • Did you download the correct version of Cirrus?
    • We have separate downloads for 32-bit and 64-bit Windows applications.
    • Cirrus will not install if you have downloaded the wrong version.
  • Did you see errors when installing or running Cirrus?
    • Try uninstalling/reinstalling Cirrus.
    • Let us know about the error at cpusage.uservoice.com.
    • See our notes below about known issues with running Cirrus.
Known Issues with Cirrus (Windows)
  • VirtualBox
    • At this time, Cirrus will not run on your system if you have Oracle VirtualBox installed.
  • Other Windows based virtualization
    • We cannot guarantee that Cirrus will run on your system if you also use VMware or Windows XP VirtualPC mode.
  • Virtualization on Mac
    • Cirrus has not been tested inside a Windows VM or partition on Macintosh hardware (Bootcamp, Parallels, etc).
Performance Improvements
Cirrus will have little to no-effect on your computer’s performance. In fact, we’ve been testing versions of our software for nearly a year and have never had a single complaint about a negative effect on performance. Cirrus was designed to stay out of your way and do it’s best work when you aren’t using the computer. That said, Cirrus will use a small amount of resources when it detects that you are using the computer at a minimal level…and you shouldn’t ever notice. Below are some settings to be aware of and some that you can change if you desire.
  • No sleep with power source
    • Cirrus default settings prevent your computer from sleeping while connected to a power source. This allows for maximum point earnings.
    • You can change this setting in the application preferences, at which time your computer’s main sleep settings will be reinstated.
  • Ensuring VT-x/AMD-V is turned on
    • Hardware virtualization will allow Cirrus to use multiple cores of your CPU, but it is not always turned on by default.
    • If hardware virtualization is not turned on, Cirrus will alert you with text at the bottom of the main window.
    • Enable virtualization in your BIOS. If you don’t know what a BIOS is, contact one of your geeky friends or relatives for help.
  • Adjust available CPU and memory
    • For most systems, Cirrus will default to only use some of your CPU cores and a portion of your memory (RAM).
    • In Cirrus preferences, use the sliders to give more or fewer resources to CPUsage. More resources result in more points.
