I think the servers must be getting hammered with all the uploads,
and so I think I will suspend my network activity on BOINC for a day or so to give the servers a break.
patience is required :)

Some of these comments are what Prof.Wallom meant when he asked us to be patient. After all, bandwidth on the receiving end is not infinite.

Since my referenced post, half of my machines have transfers suspended, which takes more than half my queue out of play -- for a day or more. (My files are no more important than those of other participants.)

Patience, please.

Patience is the virtue now. I'm allowing only 2 out of 7 machines to upload, at a combined total of 90 KB/s (about 1 megabit/s). Those two machines won't be clear of uploads until early next day. Then I'll let the others upload, one at a time.
Patience, patience.
Give the upload servers a day or three at least, to get back to normal. After an 11-day outage, that's a good upload rate.

One of my machines has now uploaded all of its 70 or so zip files. The other machine is starting to upload a roughly equal number of zips. So it is coming along nicely.

---

Three zip files left out of about 40. However all three are giving "can't resolve host name" in the log now. One of them got about three quarters of the way through before it fell over.

And now down to the last zip which has started :)

I turned off new work units on my AMD 6-core machine with SSD and 24Gig of RAM about a week ago. Was trying to be "polite" before wiping machine for new Ubuntu 15.10 release. Still waiting on about a dozen uploads. Had to abort one climate prediction job which estimated it had another 150+ hours to complete as I didn't want to wait yet another week for it to finish. Machine has a video card with 384 CUDA core so kind of odd package would take that long being only thing running on the box.

Odd that the upload server is so resource constrained when the downloads seem to happen at full throttle pace.

I can give it one more day then I _need_ to change the Linux flavor on that machine for another project.

CPDN doesn't have any GPU work, everything runs on a single core of your CPU. IMHO, multi-threaded apps would be nice but I doubt they'll be making any major changes mid-experiment.

A dozen uploads should take less than 6-8 hours, based on the upload speeds I'm seeing here now, and typical 70-90MB zip files, even accounting for server congestion.

Please don't sweat it, if you need to reconfigure or update, or change your OS, or whatever, and ditch a few CPDN models -- cest la vie. Whatever has been uploaded already -- is uploaded -- and thanks.

On the other hand, it's entirely possible -- I've done it more than once -- to save the boinc folder with its status files and the /etc/ and /etc/default/ files, and restart successfully after a total disk wipe and version or even distro change, but that takes an hour or four hours or -- of your human time -- checking libc versions, getting all the 32-bit libs right -- if you like doing such detail work - good -- if not -- a few uploads won't be missed that much.

About the relative slowness of uploads vs downloads at CPDN - some recent models download about 100MB, and upload (70*12)+90 MB. There may be other factors.

Noli perspirare, and thanks for contributing

That will happen tomorrow. I have to get up and do that in the early morning hours. Have satellite Internet here so "bonus time" is 2am-8am local time. You only get 10Gig/month when ordinary people are awake, but I'm allowed 50Gig/month during that narrow window. When I was young I would just stay up, but now I must set alarm for something like 4am then go to office to kick things off. It has been my experience that one can pull down the shiny new Ubuntu ISO only seconds after "official" release and it __still__ needs to pull down 500Meg of updates/language packs...so...have to sacrifice the sleep.

Roland,

Please note the option in boinc manager:

Preferences/network usage (option) Network usage allowed . . .
You can use it to limit hours of connection and allow boinc to stay awake late to get the job done. Hope it works for you.

Please note that settings made in boinc manager work only on that machine.
