For reference

Overflows have existed and been recorded like that since the very start of the SETI@Home project. With traditional linear applications, all quorum partners usually find the same signals in the same order, and the tasks pass validation at the first attempt. Raistmer has explained several times (but unfortunately I don't have a message link handy) that SoG and similar variant applications don't necessarily process all parts of the task in the same order as traditional apps, and the different order of signal presentation can result in failure to validate immediately. He has determined that the increased speed of SoG processing outweighs the inefficiency of requiring extra replications to complete validation. |

Accordingly, this Wu is useless. Not necessarily - maybe all those signals are ET's version of WOW! It will be processed through validation as normal, until either two results match or the maximum allowed number of replications has been sent out and returned. If it validates, the signals will be recorded in the master science database like any other WU. (or would be, if this was the main project. Since Beta is purely for application testing, I'm not sure whether any work done here has scientific value) |
