Looking through my cache, I have 26 of them. Most are from 17616, and the remainder from 20903. The latest was sent @ 19:50 UTC, the rest have been sent every few hours from 07:22 UTC today. Should we pro-actively abort these tasks or let them fly and see what happens?


If you can run them without adversely affecting your machine usage, that would be best ... to get rid of them on more reliable crunchers.


OK, I'll let them go and see what happens with my current setup. It'll take until about midnight UK time tomorrow 'till they've all worked their way up to the top of the cache and had a shot at being processed. Let me know if you want any of the output data from them.

Too bad I cannot afford it, lol.


I think the Fujitsu K has more beans:

But apparently, the Q series of Blue Geneie may well surpass even this as it is targeted at 20 petaflops sometime this year!

This is all a bit odd!!!

The daemon is running, the GUI is looking for localhost - you have work and the init file has execute permissions for all. That's the basics covered. Its been a long time since I ran BOINC under Linux and I am struggling tom understand why the daemon is not starting the processing.

If you had damaged the files, I would have expected your cache to vanish - but it hasn't - its ready and waiting!

Do you have any output in the log file?

OK.

In the BOINC GUI, have you connected to localhost? (from memory, you need to do something like, select Advanced, then Select Computer and then enter localhost).....?

The reboot was was needed, because the machine was in a kind of a freezed state - it did not respond to anything (keyboard, three finger salute, mouse movement, .. not to anything).

It ran fine for about a week and suddenly then it just did not. What I remember doing to my machine is listed on my first post. But - since - I'm not an experienced Linux user I can not tell any more of what happened to my setup.

I'd like a quick solution: Something like "yum install something"- and then copy some lunatics files with right permissions. That's all I need.

Thank You.



...see below. What is the result of ls -l ?

what are the permissions on: /etc/rc.d/init.d/boinc-client ?

You can just cd into that directory and do an ls -l

I think you have a permissions/access issues. You have a daemon running - you have work - good so far. However:

/sbin/restorecon -v /etc/rc.d/init.d/boinc-client

failed and that command should just be listing changes in file labels...

What sort of disk setup have you got? Are you using symlinks anywhere in the BOINC setup? Did you do anything to change account policies prior to reboot, and what caused the reboot.....

I just had to reboot my machine and it booted up Linux just fine (I'm typing on it
).

Normally it (the machine) would have started up crunching away as usual - except now it did NOT!

"Messages" and all other tab-pages are empty in my Boinc manager on my fedora 64-bit machine display.

My last commands on my super-user account are:
# /sbin/restorecon -v /etc/rc.d/init.d/boinc-client [this one failed]
# semanage fcontext -a -t consoletype_exec_t '/etc/rc.d/init.d/boinc-client'
[this was ok] - I don't know what it did !!!!
#semanage fcontext -a -t consoletype_exec_t '/etc/rc.d/init.d/boinc-client'
[did not complain at all] - what ever it did

I'm no expert in Linux,
Please
Help!


On my terminal window after a few minutes of panic and terror I ran "boinc-client start" and the terminal responded after a moment of hesitation green in brackets OK!

... but I still do not see any Boinc related processes running. (ps -A)

Those of You who may be pondering what the **** was he doing when he issued those commands .... -- Well, the answer is that the 'selinux AVC' said that I was supposed to do so.



Is there anything for the host to process? Have you had a look in your BOINC directory to see if you have any tasks on your host? I know there are tasks allocated to your linux host, but have they downlaoded?

Or perhaps has anyone a tip for getting a more reliable DL of WU's?

Thanks

[BOINC] > cat cc_config.xml

You'll be buying them 25 extra download servers, then? :P

Seriously, this is a community, distributed project, with tens of thousands of users jostling for a scarce resource. I would prefer to see solutions based on collaboration, rather than competition and exclusion.


I have to agree - and looking at how many hosts this person is responsible for, I sure hope that they don't all have that sort of setting. Good grief - talk about selfishness.

What is a "lost task", as in "Sending Lost task" message



A task that the servers allocated to your host - but effectively never arrived, or never finished arriving - perhaps due to network congestion. When your host reports, it tells the servers what it has in its cache - if that doesn't agree with what the server thinks you have, the servers resend any tasks your host hasn't got but should have. These lost tasks are often called ghosts.

I wonder what happened here?
http://setiathome.berkeley.edu/workunit.php?wuid=974196689



....whilst avoiding knocking the power plug out of the wall outlet and thus avoiding an unplanned outage, the cleaner accidentally sucked up a few wu's that were lying around. It'll be in the dust bag ... ;-)


More seriously, I can't recall seeing something like this before! Is (was) it one of yours?

What is it that you want to avoid loosing?

All the time to reload and reinstall all the drivers, programs, etc....
I know that I can back up and save the Boinc installation.

BTW, this would be Win2k AS to XP Pro 32 bit.
I already know that you can't go from 32 to 64 bit as an upgrade.


I think, assuming that most (if not all) of your desired applications are installed to their default Windows locations and have registry entires associated with those locations, your gut feeling is probably correct and that you cannot do it without something resembling a train wreck - even if you could get the installer to just give it a go (as I imagine what would happen is that all the existing windows directory structures would just be over-written).

Having said all of that, is is not worth backing up the entire partition, disconnecting the network cable and just seeing how far along the install route the installer goes before complaining????? You could always recover if things got out of shape....
