MiG Sandboxes

MiG sandboxes make it easy to donate the spare computing power in your computer to scientific research. Sandboxes provides a secure execution environment, which ensures that your computer is in no danger for being exposed for virus or other malware from the work it performs for the Grid. The sandbox also makes sure that your personal files and other information cannot be seen by the Grid. Thus the name sandbox; the Grid really cannot see or access anything outside the sandbox.

In MiG, there are 3 ways to contribute to the researchers work and still be fully protected by the sandboxes.

Please note: When following links from this page, your browser will warn you about entering an insecure site. The reason for this is that the browser cannot tell the difference between dangerous and harmless sites. You can safely ignore the warning and continue, all pages at migrid.org are completely harmless for your computer.

One-Click

This is the simplest way to donate processing power to Grid. All you need to do is to click on this link, hence the name "One-Click". As long as you keep the page open, your computer keep receiving and calculating jobs from the Grid. The calculations are easily abrupted, either by closing the browser window, or by directing the window to another website. At present time, only a few research projects can make use of this model, which is why we recommend one of the next two options. If you are using a Mac, One-Click with the Safari browser or with this screensaver are currently the only options for donating spare computer power.

MiG-SSS

MiG-SSS is a screensaver sandbox, meaning that the sandbox is only active when your computer is in screensaver mode. Whenever the screensaver is activated, the unused processing resources are automatically donated to scientific research. When you return to the computer, the sandbox, in which calculations are executed, is closed immediately. For this reason, one never notices that the computer was working on jobs from the Grid. 

It is also possible to install the sandbox as a so-called "service" model, this means that the sandbox is constantly running in the background as long as the computer is on, it will still only eat excess CPU power, but will use some of your memory at all times.

The screensaver is available for computers running either Windows or Linux. Please read more and download the screensaver, that is easily installed on your computer, from the SSS Page.

A thorough step-by-step installation guide for Windows users is available for further details.

MiG-PS3

If you have a PlayStation 3, you can turn it into a very powerful Grid resource by downloading and burning this software to a CD. Whenever your PlayStation 3 is turned on with this CD in the CD-drive, a custom-made Linux system starts, and connects the PlayStation 3 to the Grid through the Internet. Since one PlayStation 3 is approximately 5 times more powerful than the most powerful PC, a farm of PlayStation 3's will constitute a significant contribution to scientific research. 

The install procedure is as follows:

  • 1. Download the CD image
  • 2. Burn the downloaded image to a CD
  • 3. Put the CD in the PlayStation 3 and turn it on
  • 4. Choose: Settings -> System Settings -> Install Other OS
  • 5. Choose: Settings -> System Settings -> Default System -> Other OS
  • 6. Reboot the PlayStation 3

 

The PlayStation 3 will now start and connect to the Grid. To turn it off, just push the on/off button and wait for the system to shutdown. To return to SONY's gameOS, keep the on/off button down when powering on and wait for the second beep. Afterwards, the PlayStation 3 will start as usual. You can at any time go back to providing resources to Grid by inserting the CD and start at point 5 in the above instructions.

NOTE: If Linux is allready installed on the Playstation 3 skip the install procedure and put the following line into the /etc/kboot.conf:
