Message 8225 - Posted: 30 Jun 2005, 11:56:17 UTC

Hi,

I tried to merge two identical accounts for the same machine in my account settings, but it says:

"Check the computers that are the same as wrkstn1 (created 8 Oct 2004 23:03:40 UTC):

Select all
Unselect all"

Unfortunately there *are* not other computers listed I could select from?! This is no browser-error, tried with firefox and IE, the same results.
Please help, thanks!

regards,
Chris

I take it the computer you're talking about is the Celeron 1400?
The description of all computers has changed a while ago. So where it would be an Intel(R) Celeron(TM) CPU 1400MHz Pentium it is now a GenuineIntel Intel(R) Celeron(TM) CPU 1400MHz.

Since both descriptions aren't the same, even though he computer is still the same, you cannot merge them. Don't sweat it though, in the end your credits and RAC are still the same.

Strange about it is, that my system didn't change in any ways since then. It's still the same mainboard, cpu, etc. and even the same windows-install.
Maybe the cpu-recognition inside of BOINC has changed meanwhile?
However, thanks for your reply!

There was something in the Client that changed that also caused part of this problem. There are also communication problems that can "spawn" lists of the same computer.

If they don't have results registered to them you can just delete them, it does not affect your credit in any way.

Though I wish they had thought this through better, to be honest, I kinda liked the low "badge" numbers ... it showed you had been there a long time .... :)

Honestly, I feel a bit imposed on by this. :-/
Why not let the user decide which machines one want's to merge instead of preselecting them by an obviously faulty script?
Maybe one adds/replaces some hardware on a certain machine, even though it's still the same computer, it will appear as a new machine with a new number.
This is really odd IMO.

The description of the CPUs inside BOINC (the DC client) and the BOINC version of the servers (server software) changed. Boinc reads the details of your CPU and sends them on to the project's servers when it first benchmarks and then connects.

So if you detached at the time it was a normal Intel and reattached later on it became the GenuineIntel. Nothing has changed inside your CPU. If you would look in the code in the BIOS of your motherboard, you'd see the same description.

Yet as I noticed elsewhere, a detach wasn't even necessary. My client Boinc ran benchmarks at the time and the next day I noticed I had a new computer entry on that project, with a new name. Even a newer version of Boinc can do this. (4.19 to 4.38 added a new computer for me at CPDN)

As for adding/replacing hardware and having a new entry added, that's possible if your amount of RAM changes or you add a different CPU. Just like Windows XP will go haywire when you change something simple as a motherboard.

One of the "bad" things with BOINC is that the server code changes along with the client code. But, not all projects may upgrade the server code at the same time, or at all.

So, we may have features on one project that are different/missing on another. Usually SETI@Home and Einstein@Home seem to run the newest software for the servers first, with the other projects lagging behind some.

The reason I mention this is that in the later versions of the system software I have had better luck merging computers that were the same.

please include to the list of "host generator" additionally this:

-when a (m$) client get's a service pack/product upgrade(sw) installed, it generates a new entry.

-same host but mutliboot setup (w2k and XP for example) --> new entry;)

-a BIOS update can return a new/other processor labeling, for example from Athlon to Athlon XP --> new entry

hard to believe but true:
OC. Is for example, an athlon 2500 oc to "more", the bios cpu detection returns an other value (xp 3200) instead the value given while running at regular speed (xp 2500).


Be carefully with deleting "hosts". One day I did it and the host went away, the total credits where reduced by the number of the deleted host.


earlier clients did readout the registery, while doing the strcpy, it was done without truncating (taking the "spaces" " " away).

I think I've found my first thing to add to the Wiki. If you know more occasions where additional host IDs are added, please add them in this thread and I'll add them to the BoincWiki.

Key word is "Merge Host", though I still need to start to migrate over the page information of the BOINC Web Site Owner's Manual ... more stuff I have not done yet ...

A year ago, there were issues with boinc at the Seti forums, and people suggested that maybe XP was the culprit and to try running in 'windows 2000' mode'
When you do that, you get a new host ID.
http://lhcathome.cern.ch/show_host_detail.php?hostid=383
http://lhcathome.cern.ch/show_host_detail.php?hostid=6400

Another instance is if you run BOINC off of a USB key on multiple PC's with different Operating systems. That's just evil.
