	I understand the traffic jam after a few days of being offline. It's a shame that a lot of bandwidth is probably wasted though, because currently I only seem to get partial downloads. Work units download anywhere between 0.94% and 96.73%. Tons are stuck in download, and only a few made it to 100% today. I also noticed that a lot of workunits (that didn't download btw) are for my GPU with an estimated run time of 2,5 minutes. So if they would have downloaded, it would create even more congestion in a matter of minutes. Of course I have no idea what is and isn't possible with the scheduler, but wouldn't it be better to schedule a few long running work units after you've been offline, so you don't get bothered by those machines for a few hours and can tend to the rest of the clients? a) the "stuck downloads" syndrome is common for the servers when there's a "Traffic jam": It's normal, and will work itself out. B) The folks at Berkeley don't necessarily know what type of WU (workunit) a "tape" will produce. Sometimes a 'tape' starts with normal WU's and about halfway through, starts producing shorties. It depends on what the Aracibo telescope is doing while the "tape" is being produced: sometimes that changes while the "tape" is running. The GPU's run time estimates are often wrong - it depends on what kind of WU's you've previously processed. (With an estimate of 2.5 minutes, you must have high-end nVidia Keppler(s)!) ____________ .

I'd appreciate it if someone in the know would explain the chart. It says it's a chart for a gigibit eithernet controller. That's 1,000 megabits, yet the graph shows it's being utilized at less than 100 megabits. So what's the problem? ____________

	Thanks for taking the time to explain it, Bob. It makes sense now!

Thanks for this insight, I didn't know it was depending on what material is being delivered. I thought the data stream was just being chopped up in shorter and larger parts for slower and faster systems and some made compatible for GPU processing rather than CPU. I recently upgraded to a manufacturer overclocked GTX670 (I just plugged it in, didn't change anything about it), so you guessed right about the high end keppler. Most of the estimated 2,5 minute WUs ended up taking a bit longer than 3,5 minutes though. But to be fair I had never seen such small WUs before, so estimates are bound to be off. ____________

	It seems that the Seti Project is dying. The bandwith cap to 100Mb is probably the first step. I havn't recieved any new WU´s to process. If this will continue for much longer i will delete my SETI account on all my computers. ____________

If you haven't received any work then I suggest that you check your settings at your end as work has been flowing freely if a bit slow. Cheers. ____________

	The bandwith cap to 100Mb is probably the first step. I can remember the days when Matt and the lads, tore their hair out because we couldn't get more than 50Mb from the link. Now people are complaining because we can. Some people who make 1 post in 12 years should go and take a chill pill, and be grateful for what they get.

Satisfied works better. The flaw in your 50 vs. 100 comparison is that the increase in bandwidth has been greatly surpassed by the increase in demand, driven by better-performing computers. Al Capone: how does it hurt you if you don't get any work? If you intended that as a threat -- "Give me more work or I'll leave and not do any for you" -- sorry, but they won't miss you. ____________ David Sitting on my butt while others boldly go, Waiting for a message from a small furry creature from Alpha Centauri.

Except for the majority of current users, who never look closely at their stats, never view these forums, and are blissfully ignorant of all the alleged problems here. And in any case, Chris and I (and a few others) will always be here. Al Capone, if you don't like what is happening here, there are lots of other projects that would love to use your computing power. Be warned though, they are all just as prone to problems and interruptions as S@H. ____________

	It seems that the Seti Project is dying. No, definitively not! It has too many lives! The bandwith cap to 100Mb is probably the first step. First step to what? To death? Wrong! It's a snapshot of the present and describes the situation we have at the moment. I havn't recieved any new WU´s to process. This may be true, but the "fault" could be on your side! If this will continue for much longer i will delete my SETI account on all my computers. You're free to leave the project if you want. But you're also free to rejoin it later!

	Sorry to hear, if that's what they feel there soon will be no one left to lend them time and computing power. Wanna bet? There's a lot of possible reasons for why this project may fail, but for the want of volunteers to crunch work units comes below that of actually finding an intelligent extraterrestrial signal.

	And behold one of my computer just got one Astroplulse WU to chew on ;-) There is still hope for mankind. :-) Well there you go. Perhaps you were a bit hasty earlier? Bill W and I, and many others, are around for the long term, despite all the ups and downs that Seti has. You either fundamentally believe in this project or you don't. If you aren't prepared to ride the waves, then we all wish you well if you wish to crunch elsewhere. Yes, we are grateful for what we do get, as well as being satisfied. Doesn't mean we wouldn't like more though :-)
