I have some old device on the list that I not use, but I not find an option where can I remove them.

I agree, there needs to be a method of deleting these old devices. I am presently using two machines, but my total devices says that I have 18. No doubt over the years, machines have come and gone.
As a result of not being able to perform the necessary housekeeping on this issue, the global statistics for total number of devices may be overstated. I hope the programmers can add a delete tab. |

If you are allowed to delete a device then you destroy the audit trail, which most reputable companies and databases require. Back in the days when discs were small, RAM was very expensive, other methods had to be used to maintain database integrity and tracking, usually by regular dumps to Mag Tape drives, then these were stored. Nowadays that is not really required, although I would still expect regular back-ups for recovery purposes.
As the Device Display, by default, only show the latest devices 'actually' in use, there is no need to do anything, which afterall is extra, and would cost more......  |

Given how that number has been *used* in PR, and given IBM putting up the millions annually to maintain the grid, it can't bother me. When you open up the device statistics page you only see those that have returned a result in the last 14 days, the rest going to the off-screen history. To see them you have to change the default filter setting.
Then, when I see the 23 I have and look over at BOINCstats only seeing a few, the 23 is reduced to just a meaningless number, to be ignored. Whilst, I'm sure WCG programmers have the skill to let the count on the My Grid and individual stats pages display the additional line of an ''active'' devices count ** and add a line ''historic device registrations'', whilst the Global Statistics page can continue to tally all devices that ever returned 1 or more results, for that is what the number is. ** Active device is one having returned a result in past 30 days [BOINCstats defenition]. Deleting or merging devices to our grid... when there's 2 blue moons in 1 month ;D --//-- |

I've been looking for the answer to this, and I understand the need for an audit, or a member's join date being reflective of a device date.
For the last 4 years I have had 1 PC running BOINC, however, my device installations is 20+. If you can't remove a retired, or re-purposed device could there be a way in the future to have 2 fields under user stats of; Device installations = 21 Current Device Installations = 2 Or add a field in the device listing that says Retired or Active... something to designate an active machine or not. and a way to accurately show the number of machines crunching WU's. I'm also thinking that WCG may have a little bit more of a gap with their 100k machine quest. If I'm actually using 10% of my device installations, how many others are out there like me. I guess its OCD about having everything organized nicely. |

As the Device Display, by default, only show the latest devices 'actually' in use, there is no need to do anything It would be nice to have a meaningful output though. I have a number of devices which are either running, but not currently running WCG or which exist but are turned off but will run WCG again. The default device display is only the ones which have returned recent results. The full device display is close to useless because of the number of duplicates. At the very least, there should be an option to combine two entries which have the same name anyhow. This would maintain data integrity. It would not lose any WCG data and would make the device display much more usable. |

No, it REALLY needs to be left as is. The device name is irrelevant, it's the device ID (a separate field that cannot be changed) that everything is keyed to and without a unique device ID work results cannot be traced back to their point of origin. If they can't be traced from source to cruncher to return server then they cannot be considered genuine work units and MUST be deleted from the results database lest they be counterfeit. To put it another way, there are NO duplicates in your device list, no matter how many devices there are with the same name. Every one has a unique device ID that's used to maintain work validity and accountability.
