Network traffic's taken a dive, even though there's work ready to send & the splitters are still running.

Well I have been getting no new work since 11:40 UTC and no there is no work on the server page. Can someone put in more data to be split please?

There's oodles of work ready to be split - at least a terabyte loaded and primed.

I suspect they need to take a lot of completed work off - I bet the NAS storage box is bursting at the seams. Several people have tried to alert them - unsuccessfully - to the stuck assimilators: and the number of results awaiting validation - basically, all those shorties where one wingmate has reported, but the other hasn't - has grown very rapidly to record levels.

No, belay that, how can 'awaiting validation' be so much higher than 'results in the field'? It must include both halves of the assimilation queue workunits, too.

Yes. As it says at the bottom of the page, "Results returned and awaiting validation" is where not all computers have returned their result yet. Once all parts of a result are returned, they are grouped together and put under "Workunits waiting for validation" which is only 18 right now. Once validated, they are then assimilated. and once assimilated, they are deleted. The problem is the stuck assimilators.

And the Assimilators haven't assimilated anything for the last few days.
Log jam approaching.

Looks like the logs have hit the fan.......

And the splitters have started back up!!

Now it will probably be a bit before the backlog and bandwidth clear so we can start uploading again.

Stupid me.
Einstein servers are down so I thought lets try Seti again for Ap's.
Forgot to set the cach down to .25 day ( already had Seti/ Einstein 100/500) But it looks like I'm a day late so now I have 17 MB's to do.I got 7 first and thought let's instantly set now new work alowed. To late, so another 10 were downloaded.
11 "long" ones in total. I'm not realy happy with that.

Yeah, Matt just explained what was going on a few minutes ago in Tech News. Should be on the road to recovery now from how it sounds.

Two panic threads ago, I let slip a little secret:

Hic!

Being a little dis-inhibited, I'm going to reveal that when I turned off networking before going to the pub, I turned off networking for this project only: the code exists (no, I didn't write it) and I'm testing it. I found another (small, cosmetic-only) bug this week, which I haven't reported to the author yet, but apart from that I believe it's nearly ready to submit to BOINC as a ready-made patch. When that time comes, I hope you'll all lobby for trac #139 to be actioned. It really helps. (message 918226)

I'm pleased to say that Thyme Lawn has now officially announced this enhancement via a comment added to http://boinc.berkeley.edu/trac/ticket/139.

I find this an incredibly useful tool: it's currently holding back 7 uploads ultimately destined for Einstein, when they get their failed (again) fileserver repaired (again).

David Anderson was busy writing an NSF grant application, deadline yesterday (or today, as it still is in their part of the world). Once he's had a chance for some well-deserved sleep, I hope there will be cross-project support for him to include the facility as soon as possible.

The assimilators are slowly (very slowly) assimilating, and the validators are also slowly getting through the backlog, but now getting no work avaialble messages. Ready to send queue is down to zero & the splitters, while splitting, haven't pickd up the pace from 6/sec- usually 15/s is the minimum just to keep up with demand without building up a buffer.



EDIT- Result creation rate now below 3.

Looking at the cricket graph, it looks like the WU storage is just busting at the seams, so there is no space for new WUs to be made. The backlog of shorties needs to be returned for things to start stabilizing yet again.

I think it might be a repeat of the download/ work creation issue from a few weeks ago.
Even when the Validator & Assimilator backlogs were at their peak, work was still being pumped out at a good rate- the ready to send buffer remaining full.
But even as those backlogs have slowly dropped, the work creation rate hasn't increased.

Start of a bad day..no SETI work units... No Einstein work unit...no Bionic simap work units... no Leiden Classic work units...finally got a bunch of World Community Grid.

Seeing how David Anderson feels this type of functionality is a workaround and not needed. How are people going to get this type of control over their network connections?

It rather depends on the answer to a couple of related questions, which possibly boil down to a single question:

a) How are people going to get any kind of control over the BOINC development process?
b) How are people going to get any kind of control over David Anderson?

glad i stocked up on WU's for the mac yesterday morning.
The old p4 has two AP V5,05 so she's set for at least another 60 or so hours.
Worried about the i7 though only 7 WU's left. never could fill up the cache on that yesterday. only had 8 running with 8 standing by.
