What is PPD?

Each time your computer sends a completed Work Unit back to us, we award points in return for your scientific contribution. The more work your computer does and the faster it does it, the more points you can get. The points for you and your team are posted on our Stats page.

PPD stands for “Points Per Day,” a measure of your scientific productivity.  This is the total amount of points awarded per work unit divided by the number of days to complete the work unit.  In order to understand how a protein folds, we need to complete our simulations of the folding process in a timely manner. For that, speed and reliability are important. To increase your PPD, we recommend that you use a passkey and if you reliably complete work units for us, you may be given additional points the faster you fold.
