Well that answers my question I guess. Still haven't heard anything back yet from my PM to Raistmer. I guess I can only hope that Mr. Kevvy does indeed find the time to modify the rescheduler to allow moving of tasks both ways.

. . Amen brother!


My issue is compounded on Numbskull because even though I have been told the schedulers don't make atomic moves based on specific platforms or that it has been simple coincidence of what the splitters have been spewing out ...... but I still suspect that what Numbskull has been sent has in fact been tailored told the Ryzen processor. Maybe it is so new the schedulers don't know about it or how to handle it or something. I have been receiving an almost 100% mix of Arecibo non-VLAR or VLARs since it went online. I also seem to get a preponderance of XEON processor wingmen.

But I have had to run the rescheduler against that machine every couple of hours compared to twice a day normally on the FX systems. But without any BLC VLARs getting assigned to the GPU's, there is nothing to move.


. . You are not alone there. I don't think it is being tailored but simply that for whatever reason Guppis are only coming through in dribs and drabs. Normally whether abundant or scarce they appear in shoals of the same type 4s or 5s or 2s. Now I am getting half a dozen 4s then some 13s then some 2s. As Grant says they seem to be resends rather than freshly split tasks. And I cannot believe how many Arecibo VLARs I am getting. I cannot recall getting them so consistently before.

I also notice there is no GBT work, I think all the GBT splitters have frozen. I didn't make a note last night of what files were how far through, but the page looks pretty much the same now as it did then- 3 files at the top just started, one at the bottom almost finished.
I think Centurion is in need of a re-boot.

I didn't either take a snapshot of the GBT splitters, but I too think nothing has changed in over a day. ( I'm doing so now) I seem to remember the same tapes in progress and the progress bars haven't changed. The only BLC tasks I have received across all three machines are resends.

On a completely unrelated matter .... does anyone know how often the Top Computers database in Statistics gets updated? I'm assuming maybe once a day. For some reason Numbskull has disappeared in the listing. I was at #107 and I have checked for the past couple of days to see where it has landed after the GPU upgrade. My FX systems still appear (Keith-Windows7@#99) but Numbskull has now surpassed them in my RAC results on my Computers View page. So it should appear somewhere in front of Keith-Windows7. It has gone invisible for some reason.

Someone must have given Centurion a kick.
Started picking up GBT work that isn't resends, and the files being worked on have progressed and changed.

No idea, but I notice the Replica has dropped behind the Master, again.

Yep. It's splitting now. Progress has changed over my earlier snapshot of the page.

And now only 2 GBT WUs in the last hour.
I think it's called it quits again.

For the last couple of months in the UK I keep getting internet dropouts when posting messages. This results in double posts and I'm sure the mods have better things to do. Anyone else over the pond finding this?

Just for your info, it is not just the UK as far as I can see as double post happen to anyone, not country dependant, we have had a couple of triple post recently from the US.

I suspect it is either Berkeley or perhaps SETI@Home.

Can I ask then that this be fed back to the appropriate people please. It is becoming a tad irritating to be honest.


Didn't Richard Haselgrove post a couple of weeks ago now over on the BOINC boards that there was a lot of " work " scheduled to be done at the Uni for a few weeks , drop outs could be something to do with that .

The forums (and the web site in general) have been very hit or miss for a few months now.
Sometimes they're nice and responsive and the threads load in seconds. Other times you can be waiting for a minute (or several) just to get a forum page to load, let alone any threads.
Same for posting- sometimes instant and other times it can take a minute or 3 for a post to go through.

These ghosts cause timeouts delaying consensus results and slowing overall processing efficiency. Nothing can be done, they're just another nuisance that exists in everyone's work Que.

Easy they are using the " re - scheduler " and don't mean " Mr Kevvy's" one either . Used to be loads of threads about it back when AP's ( MB V5 / V6 and V7 ) were plentiful and people were asked not to use it coz it " screwed " with credits etc and getting round the server task limits that the staff set . Was a while ago now but i'd put money on it being the answer to " how they do it "

The easiest way to avoid the limits is to have the BOINC client not report how many tasks it has on hand.

. . 5,000 taks in progress is definitely not according to Hoyle. Someone needs to reset his project and probably his rig ...

Given the fact this guy has a lifetime RAC around 300k since 2002, hasn't consolidated the PC stats to eliminate duplicate hosts, and really hasn't done much else, the chances he's using something like that rescheduler to snag a bunch of tasks would have to be slim to none, I would think.
This does not seem to be a very sophisticated cruncher ... but nice try ...

And over 3000 of those tasks were downloaded on the 16th and 17th of April with as many as 20+ per second.

Wonder how that happened.
