Message 51354 - Posted: 10 Oct 2011, 20:21:58 UTC - in response to Message 51349.  


I have Primegrid as my backup, it is the only backup project that runs on an ATI and I consider to be at least vaguely useful... If you set the resource share to zero, it only makes the project the backup. It does not limit the number of WUs that are downloaded once the backup kicks in. I think backup projects should work the way you describe, but they don't. I checked on the BOINC site. There is no way to force BOINC to only download a single WU at a time.


Sorry, no. I use collatz as backup, I use ATI-Cards, and it's always only one wu that is downloaded.
It depends on the projects server version, but at collatz this feature works perfect.

I finished a WU last night and it went out. Didn't see any changes so THEN I read this post. Am I to understand that task is LOST?


Yes.

If we increase the cache, then this type of database crash would happen significantly more often. We just don't have a powerful enough server to increase the size of the workunit and result tables that much.


On that note...
This is my idea of a budget (best value/cost ratio) server. All prices are USD, quoted from US retailer Newegg.com on Oct 10, 2011(I do not work for them) I think we as a community could come up with this. I will put up $500 seed money.

I have started a seperate thread for this in the cruncher section. All feedback, especially from those with experience with server configurations, is welcome.

Not Included: Case/mounting hardware, power supply, raid hardware, which are all better left to whoever sets it up.

Actually you are both correct, the difference lies in the BOINC manager version that you are running.

The 6.10.xx series requests a chunk of work and it gets multiple work units.

The 6.12.xx series requests 1 work unit per idle resource.

I have Collatz as my backup project for the HD5830 and it only maintains 1 work unit at a time right now.

hm? why? how do you mean that? I have dnetc as backup backup backup emergency energywasting project when SETI Backup offers no Astropulse on the MW Machine. Normaly over BOINC Manager..


You can't just attach to DNETC and Moo Wrapper via BOINC manager.


Then plz explain it to me how i done it with DNETC when you know it that exactly ... ;)

I don't know. It's not listed for me when I go to attach a project.

I guess there was no good news to report today...

It isn't listed there (that might be a developer choice at BOINC central), but you can attach by this sequence in the BOINC client.

1) Tools
2) Attach to project or account manager
3) Attach to project
4) Type in the project URL:

For Dnet that would be http://dnetc.net/
For Moowraper that would be http://moowrap.net/

I don't know that you can do this via the BOINC account manager side of things though as I attach to projects via the attach to project option.

I was following this discussion yesterday, since I completed a nice unit and it went out to you, only to discover belatedly that you were down.

I see the "big" contributors are asking for larger work units. I don't support that at all. I understand computers always have glitches and I'm not mad about no credit, but I'm certainly not interested in using up a lot of time for nothing again. Just saying.

I am gauging the cost of an appropriate server right now.

Travis, we had problems in the past then you came with the idea to clear the database very quick, so most of us could not see the results page.
Then there where no more outages, unless airco problem RPI, not your fault.

A few weeks ago you increased the results pages (36 for me some times) this is off course a heavy load on the database and server. If you reduce this again, wouldn't it help?

He already has actually.

I'm going to have to lower the time workunits are kept in teh database, I think the number was too high and that's what caused the result table to get too large, corrupt and then crash the whole project.
