New thread as 30 has hit that magic number due to the upload problems.

I have reported all my backlog, now I just need to get some more work for the poor computers.

I even added a new computer into the mix to take the place of the one that is now dedicated to being a DVR.

No need to thank me for doing my part. I forced all my uploads through and downloaded a weeks worth of tasks before the scheduled outage to fill my cache. So at least that's one less host vying for WU's :)

Ok, maybe a small throat clear for some of you mega-crunchers, but a sizable furball for me ;-)

It's probably covered in one of these threads, but I can't find it ...

I am getting "3/16/2010 11:27:32 PM SETI@home Message from server: (Project has no jobs available)" message while the home page shows 40,000 WU available... Whats the (obvious) answer??

The obvious answer to me is that the server status page is not real-time. The "as-of" is usually 9 minutes behind the snapshot time of the page, and the snapshot time can be 0-20 minutes behind real time. By the time the page was generated, those WUs were long gone.

Can I use the word "time" any more?

According to Boinc Tasks 0.45 I have 124 WU's(Tasks), I'm getting a little here and a little there, So far It's a little over 1.5 days so far, Earlier I had 63 WU's before the slow download started, I can only hope My cache is filled before the next time.

Yah, it's been discussed before, but others are wondering too.

The "(Project has no jobs available)" message reflects the interface between the Feeder and Scheduler, a limited set of no more than 100 tasks that a Scheduler process examines to see if there are some which satisfy your host's request. The Feeder takes from the "Results ready to send" queue to refill that 100 task buffer, then goes to sleep for 2 seconds if the project is using the default setting. The type of work each of the 100 slots will get is preassigned, there are a few for Astropulse v5 and v505 but most are for Enhanced/Multibeam. If a hungry CUDA beast asks for a lot of work just after the Feeder has gone to sleep, all other hosts get the "(Project has no jobs available)" message until the Feeder wakes up and refills the slots. Note that the download pipe won't support actual download of 100 WUs in two seconds, so it isn't practical to increase the rate until we get more bandwidth.

Of course sometimes there aren't any ready to send so the Feeder can only put what's been produced since it went to sleep into the buffer. That just makes the "no jobs available" happen quicker.

Well everything cleared my end last night at around 11:30 pm.
Since then although server states that there is plenty of work to send (at the moment 110,121) my rig has had no work sent.
It keeps requesting and getting the following.Over and over for the last 6 hours.
17/03/2010 07:14:19 SETI@home Sending scheduler request: To fetch work.
17/03/2010 07:14:19 SETI@home Requesting new tasks for GPU
17/03/2010 07:14:29 SETI@home Scheduler request completed: got 0 new tasks
17/03/2010 07:14:29 SETI@home Message from server: (Project has no jobs available)
Maybe get some tasks by the time I get home from work tonight in 12 hours.

The server status page has not been updated since 04:50 UTC which is about 4 hours ago, so it looks like I will be getting no new work messages for awhile on one machine and hopefully either the same message or work on this machine. I have two WCG units to do both 15 nrs and one Seti to finished about 1.5 hrs SO sometime I hope I will get scheduler messages

Download traffic has dropped off to next to nothing.
I guess it'll give them something else to work on tomorrow.

Batten down the hatches for the next round of "Why can't I download new work" for the next 8 hours. :-)

LOL, here's the first. :-)

I noticed that.

I was surprised Ned managed to stay calm for as long as he did answering the same questions over & over again. He's got way too much patience.

I think every one of us has taken a time-out when we run out of polite ways of saying the same thing over, and over, and over again. Fortunately, there are usually enough people with recharged batteries around to take over the refrain.

I hope (and indeed expect) that Ned will be back, sooner or later - his practical daily knowledge of networking issues is a welcome change from all the speculation.

Speaking of which, I'm still trying to get my head round Eric's post: I didn't expect this to have been a campus issue - though I didn't actually look at any upload packets this time round, so it may have been different from the last set of packets I sniffed.
