I have found that attempting to "kill" or "start" tasks manually causes ownership problems when the tasks try to talk to one another. if you start or stop the client be sure to use the designated service call.


OK - do you know what the designated calls are? I'll use those.

Pasting 'MIT-MAGIC-COOKIE-1' into Google brings up all sort of references to Linux X-server (video output) problems and techniques. At which point, it stops being a BOINC problem within my knowledge, so I'll bow out.

Agree, I think this is ancillary to the actual issue at hand and should be disregarded. It's a server problem that's unrelated. (DVWA has been playing up - now fixed). It's just noise in a live terminal output.

Only to mention in passing that 'dir_open: Could not open directory 'slots' from '/usr/bin'.' sounds like possibly serious disk corruption: the 'slots' directory is pretty fundamental to BOINC's operation, and would have been created during or immediately after your first BOINC installation.

The folder exists, but not in /usr/bin. The drive isn't corrupted at all - I just tested it. The 'slots' directory is in 'var/lib/boinc/slots'
This setup was running fine and has recently stopped so it isn't an installation issue, unless KALI Linux introduced some fundamental changes, which they haven't as far as I am aware.
I've tried a fresh install but don't think I managed to delete everything so might try again tomorrow. It's takeaway time ...

my pizza is getting cold!)


Hope it was good - that's what I'll be having tonight!

I located the boinc file in "usr/bin" and ran it. I checked with "ps aux | grep boinc" to see what was running; I got:

root     16240  0.1  0.1  40804 13536 pts/0    Sl+  17:25   0:00 boinc
root     16297  1.6  1.0 102851176 86348 tty2  Sl+  17:25   0:01 boincmgr


I killed the "boincmgr" process and restarted it but I still get no connection. Starting "boinc" gives this:

Hi all,

I am sure there is a simple reason for this but on my Linux box, BOINC manager is loading at boot time but never connects to the client.

I have tried to uninstall but am not sure what files need to be taken out and aptitude doesn't recognise boinc or boincmgr so can't help me.

Is there an obvious reason for the Manager to not see the Seti app? It was all working fine but just suddenly stopped after a reboot. I'm assuming there's some lock file in place but am not sure where to look for it and it's just an assumption anyway.

TIA

Are you crunching GPU units too? I found these were ridiculously slow so disabled GPU processing and my RAC recovered quickly.

Hi all,

Looks like disabling the GPU process has done the trick! RAC has been rising sharply since.

Thanks for the info.

I've suspended GPU on both my i5 machines to see if they pick up their speed - I'll give it a couple of days and check back.

A quick check is to look at the processing times.
WUs that are presently taking 9+ hours should drop down to around 3-4 hours to complete.

Times are looking good - uploads occur overnight so, wingman-depending, I may see a change over the next few days. Looks like the Lunatix GPU element eats up too much CPU on my rig. I'll wait to make that a conclusion until I have results post-suspending the GPU tasks.

I would try disabling the graphics core and run a CPU task by itself and see if the run time improves dramatically.

I assume you are talking about this https://setiathome.berkeley.edu/results.php?hostid=8282565 host.

Yes, I am. Correct. :)

Your system however has a number of valid tasks that is less than half of the number of pending tasks.

That's odd.

One thing to check is this task: https://setiathome.berkeley.edu/result.php?resultid=5952168692. It was sent to your computer on August 18, but you have not yet returned it.

That task is not in my task list at all. I have 14se08ab but not 14se08ac. It's possible that some tasks got burned when I upgraded to BOINC 7.8.2 - and I think I added the Lunatix apps to support my graphics card at some point. That might have trashed some units too. But the Windows boot of this machine is pretty stable.

I don't think I have a stuck unit(s) - is it possible to check wingmen? I've never had a problem like that before - my rig is hardly the quickest in the world, I would imagine most users are waiting for me to finish a unit.

I've been experiencing what Hal described mostly. I think it only depends on the mix of BLC/Arecibo tasks coming off the splitters and the luck of the draw in matching up with fast or slow wingmen. The recent spate of "noisy" bombs didn't help either. I got a ton of them.


I'll see if it levels off over time, then. I'd just never come across such a large swing before.

Nice 'scope, by the way.

You don't seem to be as NVidia-GPU-dependent as I am, but my RAC wavers up or down dependent on what proportion of Arecibo to Green Bank work is being distributed; since Tuesday it's been falling as there has been more Green Bank GUPPI VLAR and less Arecibo.


Do your figures move that much, though? It's nearly halved!

(Are Intel GPUs similarly affected? AMDs are not.)


I've no idea. I do have a large stack of GPU units today.

Hi all,

I was wondering if anyone else was experiencing a drop in RAC recently?

My machines are pretty much on all the time yet the average is consistently falling. I don't know if it is a coincidence, but this seemed to start happening as the new, larger, WUs came online. Is it just that my units are pending validation or do the new units offer less credit.

Here's my desktop machine (Win10-DELL) which peaked at 6,600 and is now falling through 3,400.



Thoughts appreciated,

Steve.

Adding vsyscall=emulate to my boot script seems to have fixed this. :-)

[Did you try "vsyscall=emulate"?


Just did that and, so far (we're 100 seconds into one unit), it is working. Previously, it wouldn't complete a second of computation before raising a computation error.

Thanks for the advice!

Is this WU specific?

Does Memtest86+ and "GIMPS Prime Torture Test" complete ok?

Or something else?

Any other clues?

I tried Memtest and my machine wouldn't boot into it - Grub was modified but it got no further when trying to boot into it. I don't have a USB pen or CDR to make any other bootable media.

GIMPS is running fine - it's pretty silent on its output but it is running happily. There's "Self-test 448k passed!" messages from time to time.

I don't think this is WU specific. This box went from merrily crunching lots of units to trashing *everything* it receives. Unlikely to be the PSU as there's no other issues - the same box crunches units when booted into Windows without any problems at all. There's nothing overclocked; everything's stock.

I haven't tried modifying the boot script with the vsyscall=emulate thing. Is that the next sensible step?
