Message 1157913 - Posted: 1 Oct 2011, 15:46:29 UTC - in response to Message 1157908.  

Somebody must be in the lab, the scheduling server is now showing as disabled.

Well, it isn't disabled, because I just reported 20 tasks. Did you check the status page for the server status page? ;-)

Seriously, all of those 'status' flags are indicative only. A script tests each server/daemon periodically to see if it's in some sense 'responsive'. The result of the test goes into a disk file somewhere, and that's what we see as being the status for the next 10 or 20 minutes, until the next page update. The daemons also have watchdog scripts which restart them if they stop running.

All of which means that the scheduling server might have glitched for a second and been restarted. That's the most we can deduce from the SSP - a single server down for a single observing cycle isn't enough to conclude that maintenance is underway (and if the staff do shut a server down manually, they usually shut down a whole block of them).

Plus, today is Saturday, not a normal work day for the S@H gang.

I had success at 15:56:19, but not at 16:01:50, 16:07:27 or 16:13:19.

Think I also detect a nose dive starting on cricket.

edit]uploads are ok.

All my fault, I had most of my rigs shut down and had just restarted 2 of them. Downloads failed as soon as the 2nd one booted up and asked for work.

(Just wondering. Is there any way we can blame Misfit for this ? He hasn't been around for a long time but......)

Well, I checked the server status page just before I posted that and it had refreshed just one minute before I did. That's why I posted it as showing disabled.


TA, we can always blame Misfit. Actually, I kinda miss him. Wonder how he's doing?

Something's definitely wrong. I just uploaded a pile of units and then sent all the results in to s&h. This morning I even got some new WUs.
I am worried that this may not be what is supposed to happen ;)

For some reason my Linux pc's can still report (and get new work) while my Windows pc's all get the "unable to connect to server" or "HTTP error" message. Same thing happened yesterday when the Linux pc's were still able to get through.

The Cricket graphs clearly show that something happened about an hour ago.

Same here, I still occasionally go look at his profile when I want a grin.

More worryingly, I just got

01/10/2011 18:03:21 | SETI@home | Sending scheduler request: Requested by user.
01/10/2011 18:03:21 | SETI@home | Reporting 14 completed tasks, requesting new tasks for CPU and NVIDIA GPU
01/10/2011 18:03:21 | SETI@home | [sched_op] CPU work request: 673473.12 seconds; 0.00 CPUs
01/10/2011 18:03:21 | SETI@home | [sched_op] NVIDIA GPU work request: 154670.17 seconds; 0.00 GPUs
01/10/2011 18:04:22 | SETI@home | Scheduler request failed: HTTP internal server error
01/10/2011 18:04:22 | SETI@home | [sched_op] Deferring communication for 1 min 30 sec

The 14 tasks got reported OK, because the 'in progress' count for that host on the website is now 14 fewer than the number of tasks BoincView is counting - I never got the 'ack' for successful reporting of those tasks, so BOINC locally still thinks they're 'ready to report'.

Edit - whatever it was, was only temporary. The tasks reported properly and were acknowledged a couple of attempts later, and I got some new work.

Daren't go to pub. The only way i can get uploads and reports through is to sit here constantly hitting the retry button. Just to add insult to injury, I jave got a whole load of 12s megashorties that take 12s to abort and then 12 minutes to upload and another 12 minutes to report. Have to go now still got WU to report again and again and again....

EDIT guess what while I was typing this the report went through. Now I have 14 minutes free till the next shortie finishes. How many pints can I drink in 14 minutes?

Well the cricket graph has almost hit rock bottom, so the sensible decision is go down the pub and check when we get back.

Well it was fun while it lasted.

Pints in 14 minutes? That depends how many you get lined up first, some pubs I know you'd be lucky to get one in never mind drunk, others you could line a dozen or more up and still have time to order another dozen.
Don't bother punishing the re-try button, just retire to the pub, someone has flattened the crickets :-(

Got results gone past expiry now. I'd just like to be able to upload and report them. I have plenty of work on other projects.

Someone must have kicked the routers at HE very hard - yiiihhha
Just got 40 WUs and downloaded them in under 2 minutes, in spite of cricket nearly maxed out - and pinging the servers is as fast as never before (from my point of the world) :-) .


Only short time of happiness, ping on .13 and .16 lost in timeouts :-( - .18 and 20 are as fast as before :-) -

One rig reported on 1 Oct 2011 | 20:55:08 UTC, but only UPLoad, no work.
Also no more work from SETI Bêta, see an enormous spike at Milkyway.

I've been getting a good amount of cpu but I don't think either of my computers have received any gpu since the last outtage. Is there not enough CUDA to go around or something else is wrong ?

Boinc will fill it's fastest device first, be it CPU or GPU, then once that cache is full it will fill the other, (it seems to be operating the other way round at the moment through)
You can try reducing your Cache setting until Boinc no longer asks for CPU work, once the HE link behaves itself you should get some GPU work,

cricket graph seems to be coming back to life. Whoever Jeff kicked, bribed or sweet talked to sort out the connection issues seems to have done the trick
