and another freeze on my main machine, no fun
so I set: no new tasks - and hope last 4 on this computer might survive

2 other computer seem have less problem, but also a lot mistakes, and gone

1 computer gone, have to open and search failure: ... HP desktop used ... 5 beep at start ... and all can run is crazy fan

another freeze in the evening - , same computer- and afternoon 4 tasks with failure computing
(it is a bit like nonsense energy using) hmm - but if continue like this, they are all gone fast, without a result

suddenly 6 tasks crashed with a computer freeze, reason not known, as not any other program run as normal.
I guess this 6 task goes back, and will be run somewhere ale again. Good luck

Batch 835 hadcm3s for Linux 7470tasks.

404 left to take, 3320 in work (? 7470 - 404 - 3320 = 3.746 area stored at computers for later start, like at me 18 I guess)

here are
* i7-4770 : 8 on work (7d10h est), 4 more ready to start
* i7-4770 : 7 on work (7d11h est), 14 more waiting to start (mean ready in another more 16 days)
* i5-3470 : 3 still Weather At Home 2 (wah2) v8.24 windows_intelx86 (one failed earlier)
* i3-2100 : 4 on work (11d14h)
I do my best and let them run also night, not only on sunpower

...You only got 4 on your i7 because only 4 tasks were available at the time boinc requested work.


THAT is some new information, that is/was not available for me (or maybe others) to understand this case. hmm ... so wait for some new big one.

and anyway,
as my solar energy is build in now, all this work will be done during sunshine hours, mean just 1/3 of a day, also to prevent climate change by this tasks energty usage. Will then take 25 days instead of 8 but as said, we are not in hurry. Sure ?

since before my last post (30 Aug 2019, 15:12:34 UTC) I didn't change any configuration.

The settings are: all 100% CPU AND depend on Work (400), home (200) or school (100) the share.

The ID 1487938 is a Win7 Home computer setup with 100% CPU and share 200.
The computer has 4 CPU and got new tasks on 1.9. ... there are 4 tasks running same time, mean 4 CPU run 100%.

So what ... ? mean CPU % and share now ?
Real CPU 100% is all CPU or one full CPU

al last on my 8 CPU computer with CPU set 100% i got just 4 tasks run same time.

I have seen a thread over on the BOINC boards which explains how the time between requests increases when a project has no work.


Nice, whatever I try I dont find it again, as increase should mean a change that can be followed. All I have seen yet is 4 hours wait another 1 hour, and after just nothing anymore.

Confirmed 2 times today again. I have to update manual, to keep all 4 pc read to get Tasks - otherwise - so my meaning - they are set as offline, and wont get any Task.

Somewhere in the boinc wiki I found a hint about the communication, telling like slowly longer time to reconnect from low to maximum a day.
Cant find it again to link ...
* "Communication deferred ...: The client will wait the specified amount of time before attempting to contact the project server again. If no communication is required at that point, none will be attempted."
= last point I got again to what I miss now ...


So to come with facts I started 4 of my computer last evening:
1st screenshot from 21:53 ITC (14:53 UTC) shows Last contact
* pc i7-4770-32 = 14:14 UTC
* pc i7-4770-32b = 14:27 UTC
* pc i5-3470-9 : 13:55 UTC
* pc i3-2100-16 : 14:23 UTC

then after the night with check "your computers" at 5:20 ITC or 22:20 UTC there are
* pc i7-4770-32 = 14:14 UTC stopped 18:17 UTC with reconnect, or waiting now min 4 hours
* pc i7-4770-32b = 14:27 UTC stopped 18:30 UTC
* pc i5-3470-9 : 13:55 UTC stopped 18:15 UTC
* pc i3-2100-16 : 14:23 UTC stopped 17:36 UTC
after 3 or most 4 hours there is no any update anymore.
And as a slow rising of reconnect I might believe that after 1 hour for some hours, take 2, 4, 8 up to the written max of 24 hours. (Never tested so long to see if 24 hours are even true, without touching the pcs)

Result:
When already this description is different from what I can see and get facts about backstop referrer, how I should believe in anything else (told or written here) ???

Now what ?
Update by manual .... sometime as now they are shown all with Last contact around 22:27 UTC

Yes, most of us where or are programmers, as I also learned it.
But as programs and all are made of human, there will be mistakes.
So we have a look forward.

And as long still Tasks are processed from so much computers, I am sure there are some basic mistakes in how to collect the computers should do a Task also (dont repeat that we have time - 2 Months of this part at so much power still in work, haha).
I hope that mistakes will die out - as human should extinct it will come as I want.

So back on topic easy fact:
It is an 4/8 Core/Thread CPU i7-4770 (realized as 8 processors)
setting was 200% CPU and share 200.
So explain me and others here how I could have 4 Threads running, with this settings that both seam (as programmer and logic ???) the reason for my surprise on 2.8.19 with 4 Tasks.


And then I see this: Tayloring BOINC settings for cpdn
* Leave tasks in memory while suspended? : sure, as keep in 32 GB MEmory will avoid rereading, but that this need also "recalculation" is strange. Explain ?
* Suspend work if : as I read only one Thread/Work was possible to get, sure no suspend - there are 7 other processors doing my normal work.
* Use at most : as still thought I get 8 units/Tasks I set it to 90% / 90% and wow, my tasks didn't fail also. So here also please logical responce on what might be the problem ? (take much longer or what, check my 3 Tasks done and tell me that they are as fast as possible or not = then we get a point about this "use at most x%") (But anyway, as with 100% cpu and 400% share I can do it to 100% now also - so less work, no problem.)

I HAD 4 Tasks same time on my 4/8 CPU. Two of them failed after short time, and 2 was still running and got ready.
I have seen clear 4 times/different 100% used Threads on Htop.
Everyone can decide by own ... and we see what will be with next bigger deliver. I have been also a good analytic for 20 years IT specialist.

So I see a clear difference in % of CPU, what cant be more than 100% if not over-tuning,
but I focus on the other explained setting (Resource share diff to 100).

Maybe as in July and August abut the 1st September we get again, some of the failed Tasks like I had 2 times before. So I keep my computers on from 31. and will press Update after about 5 hours, as I have seen, then the last connect keep stand and got old. Never know what that might mean for get new Tasks also. Wiki describes this Backoff or referrer with a start of min 60 sec, getting longer up to one full day. Never tested that, but sure at my 24/7 server after 5 hours there is now new updadate in last connect anymore.

Post:
Choosing 50% for the "use at most xxx % of the CPUs" will allow just 2 tasks being run at a time on that i3.
Didn't work for me, as have 100% on 4/8 Cores/Threads and took only one.

What WAS working is set the
* Your account,
* cpdnboinc preferences
and here
* Resource share from 100 to another number,
for Example I used 400 and then I got 4 CPUs loaded of 8, so far I can tell that after just 3 Tasks successful, 2 failed - mean had 4 on 8 Threads running.

so at the 8 Thread I use 400 to use 50% of all,
and at the 4 Thread CPUs I use 200 now and will see if also 50% of is bussy next time.

A lot seem to go to computers that spend much of their time switched off.

Yes, and I told why this seam to happen before.
24/7 computers get bigger gap report available and stop report then - as often off computers are fresh updated with "I am ready to take work",
seen at home , tested with 6 computer here.
But someone wrote, it might be not urgent to get results.

though whether it is really accurate is another question.

Jepp,
Tasks in progress : 84.082 - against
single sum : 928 + 2320 + 55430 + 4815 + 286 = 63.779

but UK Met Office HadAM4 at N144 resolution was at start 1.7.19 about 626, and is now 286, so 55% done. I did 2 sets of it in each 7+ days ... so also most others seam to be slow ....

and again Facts:
2 computer run 24/7 last day
* ID: 1487884 show 5.8. 19:49
* ID: 1487908 show 5.8. 11.37
* ID: 1489649 offline since 8:39, so no update
but now is 22.18 UTC (5:18 local), and only after pressing update at Project Tab, brought up new time at both.

I think that ...
Please make sure that you get the knowledge about this,
as following is wrong then:
* a 24/7 computer, that highly might also be 24/7 work out an Task, is getting low ranked as more and more time over 1 hour "old" (ready to work)
* but most often restarted computer, that might also often be OFF, get better ranking, as most time after restart they have just 1 hour diff to last report, and are better ranked.

Result: Tasks are going to the wrong computers, and take much longer than needed.

Also: Maybe there should be a also rank memory about how fast a computer did a task (needed real time against calculation time) to focus more on fast and 24/7 running computer.

AS then they (sientist) get back faster complete result, and also might be able to prepare also faster a new set, as they see, its worth to use boinc ... as the climate change is real, is fast and we loose time. We cant stop it anymore, but we need to prepare for it with this calculations.

I am writing about,
that if I open the page/link "my computers" then the (here 6) computers are shown in order of "Last contact", where the latest updated computer is first.
And so all computer running 24/7 should be first in the list, with just an diff of LESS than an hour.
Computer, off in the night, will have a last contact of more than 8 hours next morning, ok.

But that isn't with the 24/7: even I am sure 3 are/was running until yesterday, most in the morning 2 of them are not updated to be available for more than 4 hours, even the manager is open, and open at Projects page.

For my understanding there is something wrong - as ready for work computer should never be reported with a last contact as more than an hour.

So now the working computer has last contact at 6:47, but the 24/7 game server is now shown with 4:20, but that should be not more than an hour behind, mean I might think that should be 6:20 as it is running also, and open boinc manager.

Post:
after again, the computer "web-server" had been 7 hours after actual "ready to work Tasks" in the list of my units, I shut it down.
As basically I have normal 2 PC running 24/7 and would easy be available to work, but they are too often not "ready", and my work pc gets the Tasks, which I wanna to shutdown in the night but as I think climate change and its prediction is imminent to look for - I let it run when there are Tasks,
I have to mark this pc no new Tasks, as this is against reduce climate change, when I polite the world with more CO2 then it makes sense.
