Hmmm.
Server status page shows green, network traffic shows nothing.


EDIT- looks like downloads are working again. Uploads still hot happening though.

Is it only due to AP burst or is there problems with downloads? I do get some through but I have many projects backoffs.

A storm of shorties seems to also be part of the problem. Results out in the field went through the roof during the last couple of hours, and looking at my own caches, I did get an unusual amount of shorties during the last 12 hours.

"Part of" ??!!

I don't think the splitters have produced anything except shorties for the last twelve hours! I did a spot check earlier, and had over 300 tasks stuck in the queue to download (across five machines). Fewer than 10 of them were 'normal' AR - and those were all re-issues. Every single first-issue task (_0, _1) was a shorty.

Yes, now that I have been looking deeper into the issue, I admit that the "part of..." was an understatement :-)

Edit: And may I also add that if they don't fix this within the next 5 to 10 years, I'm out of here.

Took an hour or more, downloading 8 AP tasks, while I still have at least 20 on
This host with 2 HD5870 does a lot of them. Deadlines are far enough ahead to justify another 50 AP tasks :)
And, again quite a lot of MB, shorties, alsovlar's, shorties take 4, 5, 6 minutes
on a GTX480(3 at once) and GTX470(2 at once), times are ~10% shorter.
The 480 has 1 Compute Unit; CUDA Core more, 15, then 470, with 14.

Forgot, this is the SERVER problems thread, so deleted it.
Not really experiencing bad or none connection at all, sometimes it appears to be overloaded. Responding with an http error and in most cases, still UP-- & Downloads.
But DownLoads, also UPLoads are sometimes very slow!

(If you have Broadband, probably very often (A)DSL and thus not
check BOINCs NetWork Settings, not to 'start' or 'stop', I think that's for a MODEM,
so 56KBaud (bit) per second ~7KByte/sec. theoretically.)

So, no real troubles here, saw when getting home, that fiber was put in the ground,
Network demands are inclining, at a fast rate, even in this very little town ;-)

Good one! ;-)

<edit> Maybe it's because while they have the hardware in pretty good shape, it was time to get rid of some of the chaff. :-D

Is anyone else experiencing d/l problems? Both of my machines have been attempting to d/l since 23:30 last night. The cricket graphs haven't been updated since 06:08 this morning.

Yes everyone is experiencing UL/DL problems right now, and as was mentioned earlier the reason is there is a lot of short runtime work being split currently.

BTW, the Cricket graphs are being updated properly. Don't forget the timeline shown is PDT.

The only issue I have seen in the past few days was between 3:49AM and 4:37AM this morning. Some downloads went into backoff several times during that window, but it cleared up afterwords.

Might have been showing that, but I just this second uploaded a completed WU.
Might have been offline for just a short bit as the status page was being updated.
Current status is green.

I hit the retry button once on the Frozen 920 a bit ago, it had a ton of work in the download queue.
After about 30 minutes, it all has cleared.

I've noticed i'm starting to queue up a few longer Work Units for download, but there's still a lot of shorties there.

Intersting the effect of shorties has on cache size.
Usually my cache is around 500-520MB in size, with this shorty storm it's now up to 640MB.

Your cache is defined in the number of hours of work it contains.
Each WU is about the same number of bytes.
Lets say 1 "normal" WU represents 1 hour of work and a "short" WU 0.5 hour of work, and a WU contains 300k bytes of data.
Your cache is set at ten hours.

Simple sums:
If all the WU are "normal", then you will have 10 WU, which will contain 3000k bytes of data
If all the WU are "short", then you will have 20 WU, which will contain 6000k bytes of data.
If 5 of the WU are "normal" then your cache will be made up of 5 "normal" WU and 10 "short" WU, a total of 15 WU, so your cache will now have 4500k bytes of data.




(I've kept the numbers simple - I know the file size in not 300kByte, and the calculation times are not 1hr vs 0.5hr, so don't shout)
