How are Team Points and Personal Points Distributed?
Points that you earn are only credited to a team if they are earned while you are a member of that team. Additionally, if you quit a team or join another team, then the points that you earned for your previous team will stay with that team. You cannot transfer credit you previously earned to a new team.
Any points you earn whether you are on a team or not will always show up under your personal statistics.
You can view the points that you have earned for different teams at the bottom of your My Contribution page.

Why are points on the agent and the web different?
World Community Grid in the past ran two types of agents. A United Devices (UD Windows) agent and a BOINC (Windows/Linux/Mac) agent. Today, World Community Grid only runs the BOINC agent. Points contributed by both of the agents will be part of a member's total on the website. However, only points contributed by BOINC agents will be shown on the BOINC agents. The points previously earned by a UD agent only appear on the website. Additionally, due to differences in how the agents computed points, BOINC points are multiplied by 7 when they are imported into the website. Thus if you earned 5 BOINC points, you will see 35 website points.
What is validation?
World Community Grid is a volunteer computing grid. This means that work is being sent to computing devices that are outside the control of World Community Grid. Most devices that perform this work are reliable. However, there are a few devices that are not reliable due to things such as users over-clocking their machines, memory errors, disk errors, CPU errors or viruses being present. This means that the results returned need to be validated to make sure that they represent the correct answer.
We perform three different types of validation at World Community Grid:
- Redundant Computations: In this type of validation, two copies of the work unit are sent to members devices. Once both results are returned, they are compared to ensure that the results are identical. If they are, then the result is accepted. If they are not identical, then additional copies are sent until several devices agree on what the result should be. This policy establishes a very high level of confidence in the reliability of the results. Mapping Cancer Markers and Uncovering Genome Mysteries are examples of projects that use this technique.
- Single Validation - Type 1: In this type of validation, only one copy of a work unit will be sent to a device if the device is "trusted", that is, if it has been participating long enough and returning good results. If the device is not trusted, then it will still be assigned the work unit, but a second copy will be sent to another device and the rules for redundant computation above apply. As a precaution, the research code computes certain items that allow us to quickly check on the server if the computation is likely to have finished correctly. Additionally, trusted devices are randomly sampled to have their results double-checked. These techniques provide a very high level of confidence in the reliability of the results. FightAIDS@Home and Outsmart Ebola Together are examples of projects that have used this technique.
- Single Validation - Type 2: This is similar to Single Validation - Type 1 except that due to the fact that different results are generated each time the work unit is run (due to the research techniques applied in the application), we send out many copies of each work unit. We currently do not have any research projects utilizing this technique.
