Project Update

[MaDr]

Once again the sending of workunits has been halted for a while

In order to gain more resources to clean out our database, we won't be sending out any workunits starting at 16:15 UTC. This message will be updated as we progress.

Soooo, MaDr, you volunteering for Seti? Accepted

[TigerWing]

yep MaDR..you're busted
welcome in our little club of Generals...
lead your regiment as it was your own pc

Greetings General MaDr,

You mission if you choose to accept it (and you did, yes you did ) is to lead the BOINC.BE Seti Division to a glorious victory in the Seti rankings.

This message will not self-destruct since the High Commander (hi Deri ) would kill me if the forum goes down because of me.

[MaDr]

Newsflash:

We probably won't be back up until Thursday around noon (Pacific time)

And from the Technical News section:

January 4, 2006 - 21:30 UTC
Well right now we're in the middle of another self-imposed outage to clear the pipes. The BOINC database compression on Monday helped a bunch - enough that the final troublesome queues were draining, but not nearly as fast as we would like.

Here are some numbers: Normally the entire BOINC database, when unloaded to an uncompressed ASCII file, is about 17GB. This is largely due to the huge workunit/result tables. Because of assimilator/file deleter issues, by December 21 the database swelled up to 26GB. On December 28 it was 31GB. Unable to purge old workunits and results, our database ended up nearly double its normal size! No wonder we were in a world of hurt.

After the new year we recovered a bit, and the compression on Monday brought it back down to 26GB. But we still had this annoying backlog of a million workunits and four million results, and until we got those purged, we weren't going to get any smaller.

This morning we turned off the scheduler to allow these queues to finally drain. We estimate it will take until tomorrow morning to clear everything out once and for all. Better to just bite the bullet and fix it rather than watch and hope for improvement during the coming weeks. When the queues all hit zero, we'll do one more quick database compression/backup and get back to work.

So let's cross our fingers and hope for the best.

General??

Any info about the credit-loss?????

[MaDr]

After checking around, I found that there were no statistic files produced today.
The ones available are from yesterday.

And the Project is still chewing on his database.
Hopefully everything will be OK after the weekend.


Boincstats.com has corrected the problem, you should see the SETI stats again.

Here some fresh news from the frontline

The outage is over, but there will be a long period of time as our servers work hard to catch up. Connectivity will be intermittent as we return to normal.

From the technical news section:

January 5, 2006 - 23:30 UTC
We're back on line after a day-and-a-half long outage during which we were able to clear out enough of our BOINC database to get us back to the same levels as in early December. Of course, there's going to be a painful period as all the BOINC clients clog our servers with demands for work. This will push through eventually as it always has. Meanwhile the master database merge is going along swimmingly - the result and signals tables are copying over much faster than expected.

[MaDr]

As the battles continues

January 16, 2006
It looks like we may be experiencing local SSL network problems again. If so, this will likely be fixed tomorrow. Today is a university holiday. In the meantime there will be intermittent problems contacting the scheduling server.

So the download of new WU's will give a lot of "No work from project" messages.
Be patient, they will succeed eventually

[MaDr]

The end is near

We are almost done with the science database merge. During this operation we are unable to create new work, so we eventually ran out of data to send to our participants. We hope finish up and start creating new work later this evening or by tomorrow morning.
