A tasks's outcome is defined if its server state is over. Possible values are:
| Unknown | The task was sent to a computer, but the computer has not yet completed the work and reported the outcome. |
| Success | A computer completed and reported the task successfully. |
| Couldn't send | The server wasn't able to send the task to a computer (perhaps because its resource requirements were too large) |
| Client error | The task was sent to a computer and an error occurred. |
| No reply | The task was sent to a computer and no reply was received within the time limit. |
| Didn't need | The task wasn't sent to a computer because enough other tasks were completed for this workunit. |
| Validate error | The task was reported but could not be validated, typically because the output files were lost on the server. |
