Message 862511 - Posted: 5 Feb 2009, 23:57:23 UTC

Spent a large chunk of the day actually programming, which is nice. It seems like the network bandwidth bottleneck part of our malaise over the past couple of weeks has finally gone away - we're back down to a floor of 60 Mbits/sec. However, the mysql database is still quite clogged up. Looks like as I type this sentence we're still having fits as the splitters/feeders/etc. can't get their queries through fast enough. I'm hoping the bandwidth drop means the excess results were all finally downloaded, which means in the next few days they'll return, and we can finally get them validated/assimilated/deleted and out of our hair.

There was a sweeping change in web code brought on line this afternoon. This broke web account authentication, making it impossible for people to log in. Oops. Not my bad - don't kill the messenger. Anyway it was fixed quickly enough.

No - see my reply yesterday. It means you are now splitting work from the new observing year, which - fortunately for the servers - has a 'drift' survey replacing the 'basketweave' survey. These mid-AR tasks take 3 or 4 times the computation time of the high-AR tasks, but the same splitter and download times. Increasing the client/server workload ratio by 4:1 is a Good Thing as far as the servers are concerned.

It's impressive how on top of this you are. This may very well be a large part of the current benefit we are seeing.

Someone know when the official SETI@home CUDA >= V6.09 will be published?
BUG-free and speed optimized [for VLARs or all ARs] ?


Thanks a lot!


Yes.. I asked this also in the NC-forum..
But no Berkeley-crew-member answered..

It's that "View from the bleachers" analogy you used a while back. When one has the luxury of stepping back from the minutiae of coding or server-fettling, it's easier to pull together the threads from a wider skein.

I see the changes you made to the web for the view of our computers on our account. One thing, you may want to remove the link to the stats site for stats.free-dc.org. The stats from that site were last updated March 20th, 2008 so are nearly a year behind!!!

Well, when I click on the link from within the My Computers web page, this is what I get:

Those stats are nearly a year old.


EDIT:

OOOOPPPSS!!!

I was looking at the create time. I just realised that is the date that specific computer was added to that project. My mistake.

I hope this is the right place for this comment. I have been unable to send any work to the site since 27 Jan 09. Einstein seems fine and SETI was fine before too. Actions so far:
- Looked on here and seen some chatter about capacity issues, but to be honest alot of it did not make much sense to me.
- However, configured the cc_config.xml file has suggested recommended, no joy.
- Upgraded to BOINC 6.4 from 6.2, but that still did nothing to fix the problem.

Any ideas, please?

Hmm, it looks like your host 3260510 got two Tasks just about 3 minutes prior to your posting. If your luck is like mine, you started composing the post before the Tasks were sent.

Although there have been a few short periods during the last 2 weeks when there wasn't any work available, I'd guess your host was working off debt to the other projects you run and not requesting S@H work.

Hi,

I run SETI on 2 machines. I get now again WU on my windows machine but I have not received a WU for weeks on my Apple machine.

I have checked the settings and can not find out why I should not get any WU.

Thanks
Sigi

Hey Guys and Gals

Anybody have any idea why the validating server is having a hard time with CUDA units??. I have 20 or more WU's that have been verified by another user but yet no credits for these,in the past several days now. Some of the WU's are CUDA vs. CUDA both with the same outcome,sort of baffling to me?? But anyhow I am sure you guys know of the problem there at seti and as usual will come up with a solution where time permits.Happy crunching folks
