I've gone back to x41zb as a test as the previous post was ll under x41zc, why did that happen? I don't know.

Where can the newer x41z be downloaded? I'm still running x41g

Well from 12:07am on My PC was told, sorry You have plenty to work on, so You get no more, yet there was nothing to crunch here...

Sounds like a VLAR storm, or just AP Wu's going out, but you were also sat on your 100 task limit,

Well as long as the PC is able to report, the limit isn't per day I'd hope.

That's because most hosts have all the MB tasks that the current cache limits will allow.

And I wonder what's gonna happen when the MB splitting stops.

The server status page stopped updating almost 3 hours ago, but at that time there were only 3 channels of MB data left splitting.
And 37 channels of AP data that have not even started to split yet.

I suspect there might be a lotta tears and empty GPUs if they split nothing but AP for days to clear that data out.

Yes, we do seem to lurch from one extreme to the other. I'm one of the people who suggested cutting down the number of AP splitters, so that the AP side didn't consistently finish a long way ahead. But cutting down to just two splitters (on an old, slow, server at that) is a bigger correction than was needed.

According to the server status page Lando has been disabled for several days, must still be having a problem with it even though Matt said it was rebuilt from spares. 2 MB splitters & 2 AP are down and out until fixed.

Yup....
And I wouldn't give it a second thought except that now of course I can't cache enough work to ride it out due to the dang limit solution to band-aid past whatever the true problems are.

So this is how S@H would work without AP and 10-day cachers.
Smooth. I only wish they would set up better limits than absolute per host.

Smooth?
I suggest you look at the netwrok traffic.
Also what was the outage we had just the other day? The splitters (for some reason) are still struggling to produce work & the assimilators appear to now be working, sometimes, at an increadibly slow pace.
Limiting tasks hasn't fixed anything- the problems are still there. It just makes them less noticable.

The limits would have been hit several times since they were introduced, but this is the first time i've seen those data spikes in the outbound traffic & the ripples in the inbound.

Your typo made me think of the "regular Tuesday outrage." Maybe we should rename this "netwrek traffic."

I just had to restart my i7's Boinc Manager because it said it couldn't connect to the internet. Once I did, it flushed out huge numbers of uploads for both Seti and Einstein. Then it downloaded a huge number of new tasks for Einstein. When it asks Seti, it gets "no tasks are available for SETI@home v7." Well, what about any other Seti project? Right now I have four (yes, 4) Seti units for CPU and none (0) for GPU. At least they're on board; no ghosts.

Update: since I wrote this, it tried several more times, and one of those times it got 61 tasks for GPU. But then on the next request, it again got "no tasks available for v7."

Setiathome v7 hasn't been released yet at the Main Seti project, so therefore there are no v7 tasks available, so you'll always get that message when you're got the v7 preference selected and you ask for work (until v7 is released)

If you're got a huge amount of Einstein tasks, perhaps the CPU cache is full now, was Boinc even asking for CPU work? were there any other lines saying eithier 'no tasks sent' or 'no tasks available'?

Claggy

I believe I have all Seti projects enabled for all processors (aside: I just set up new venue rules for GPU only, but there is only one computer in that venue and it's not this one). Yes, I believe the work request was for both CPU and GPU.

I can't really tell whether it's the kitty or the tail that's getting wagged. Is it getting lots of Einstein because it can't get Seti, or is it asking for limited amounts of Seti because it has so much Einstein? It's done so much Einstein lately, there should be a huge debt to Seti.

This machine's Seti tasks in progress are always 104. It reports some, it downloads more, it always has 104. When I check the manager, that breaks down to 100 GPU and 4 CPU, but whenever I look it's always running Einstein.

[edit] P.S. Now that this thread has gone to a 5th page, I can see it at work again. Whatever our security or nanny filter was barfing on must have been specific to that page. Probably an image's filename or host server.

To see the debt go to the projects tab and select a project. Click on the properties button. Might need to scroll the box down.
<ed> on 6.x Both the work fetch and CPU priority numbers are displayed.
On 7.x a single priority number is displayed.

IIRC they run from zero to negative infinity.

I suspect there might be a lotta tears and empty GPUs if they split nothing but AP for days to clear that data out.

If they were to do that it would be interesting to see how long it would take to split all AP tapes

It would appear that they took the unsplit AP datasets out of the splitter queue and loaded a bunch of new ones. Because when I look now, after getting home from work, there is once again much MB work to split, and very little AP being split.

They must be setting aside the AP work for a time when better server solutions are in place.
