No problemos here.
I got all 1800 tasks I can get. The kitties have been sniffing 'em out and crunching 'em down.

The chinks in the upload bandwidth on the Cricket are a little worrisome though.

Bandwidth ... than useless server chatter with no results.

Yes, we need more bandwidth to fully sort comms difficulties, but Matt has proven that proper server configuration can also go a long ways toward fully utilizing what we now have.


Whatever tweaks or adjustments Matt applied recently have really IMPROVED the DL /UL /Report throughput (and now few stalls) for me, just over the hill from SSL. Prior to those tweaks, I seriously contemplated pulling my plug on SAH from so much communications frustration. Now greatly improved, I'll stick around to atleast reach my 14th SAH Anniversary in April.

Kudos MATT!

My comms are doing fairly well, too. Every now and then I need to use a proxy to push the AP downloads along, but usually just 3-5 re-tries without a proxy and they'll go all the way through.

My single-core machine oddly doesn't have that issue at all. In BOINC Land, nothing ever makes sense, and nothing is predictable.

I thought I had a way to fix the bandwidth problem this morning -- National Lottery sent me a message saying, "We've good news about your ticket in last night's Euromillions draw!" Alas, it was only £5, not £500,000...

The curious Cricket blue line hiccups continue:

I wonder if this a symptom of a problem or whatever was done to cure the greater difficulties?
Looks like another downward cycle is starting at present.

Might be a bit wonky, but so far the rigs seem to be able to keep the work flowing.

And it's weekend again. Scheduler request failing time after time.

I guess I was a bit quick to start whining yersterday, because it seems it was only a glitch. Everything is working perfect ever since.

Well, my problem seems to be solved.

I have uppgraded to BM beta 7.0.4+ and now getting a funny answer in messages when requesting new work.

2013-02-17 09:29:52 | Moo! Wrapper | Not requesting tasks: don't need
The same goes for SETI tasks and if tasks are in transfer it doesn't ask for more either.... and with alot of stalled transfers...


And work cache is set to 3+1 days and i only have a cue of 2-3 hours....

I hope they are working on this.
I made a thread in Boinc Forum about it

http://boinc.berkeley.edu/dev/forum_thread.php?id=8196&sort=6

I hope they can sort it out.

Well, here we are back after a most unusual outage. Even though the web server went down, the project servers kept going and work continued to flow. Sometimes, it's quite the opposite, LOL.

Yes, the project ran well without our gripes and panic posts. Wonder if.... Guess it is time for the usual maintenance window, and I got so many astropulse tasks during the blackout I can make it thru maintenance.

Hope to hear more about the cause of the web server downtime.

Don't know the exact reason it happened, but thinman, the web server, crashed and could not be rebooted by remote. Eric tried. And since yesterday was a campus holiday due to Presidents' Day, nobody was in the lab to restart it.

Maybe if you didn't saw it already on the 1st page: http://setiathome.berkeley.edu.


Lab-wide Power Outage This Weekend (Feb 22-24)
Once again we are going offline due to electrical repairs in our entire building. We plan to come down Friday afternoon (15:00 local time) and be back up by Sunday afternoon (12:00 local time). All SETI servers will be unreachable during that span. 19 Feb 2013, 23:58:59 UTC


IIRC, the SAH lab is UTC -08:00.
This mean currently Germany is 9 hours before ..
This would mean Saturday 00:00 to Sunday 21:00 (MET).

That's cool. My first time ever getting this..

2013-02-20 13:20:06 SETI@home Message from server: This computer has reached a limit on tasks in progress


I was stock-piling for this weekend's outage and I found a proxy that works pretty well for AP DLs.. so I changed from 50% of CPU cores to 100% for an hour or so and then switched back when I got to the limit. I'm good for about 17 days now.

Why not increase the limits for this special occasion? Double?

Well, it looks like we're back from whatever partial outage we had last night.

Anybody get any details of what happened from one of the guys?

So far, the servers have come back live and hot. All 9 rigs have reported their uploads and are receiving fresh work!
The kitties are happy campers again, and I can shut the furnace back off.

I do wish the limits could be raised to allow some increased caching for the coming weekend's scheduled outage, but the kitties are not gonna hold their breath on that one.

Also it would not make sense to increase it, I'm pretty sure the bandwidth will be maxed out until the planned outage, i.e. they will send out as many WUs as they can either way (and also probaly assign a lot of WUs, which can't be downloaded before they shut down).
