41) Message boards : Questions and problems : boinc "box" with DCLinux (Message 42073)

I am not sure how old Lenny


It's old-stable. This February lenny is off security-support.


is but it might provide an older BOINC version, I am guessing around version 6.10.58 which was and still is a good version that may serve you well for a long time.


It's squeeze what's bearing 6.10.58. The boinc of lenny is 6.2.14


DCLinux might not provide an OS update so you would be stuck updating the OS yourself.


Some believe it would be easier to just build it yourself. You (not *you*, but you, who's building) have to learn anyway.

Originally I had thought that it could be used as a sort of 'Bragging' point- a sort of "our company is better than the competition, because we help fight cancer, etc..." In fact, I still think I could probably manage to convince a few companies to use it as an advertising point- AND potentially start a trend or something...


When I was practicing that Other Religion I'd seen Google among contributors. Things could have gone FUBAR since then. And I've never seen Google mention it was couting F@H.


*IF* there's any possibility for deducting the value of donated cpu time from corporate taxes.


Sure it is,.. No, it's possible to achieve that goal. *You* have to bribe... No, forget it, you have to contribute to some lawmakers upcoming elections. And they will do anything you want.

That's not arrogant. I like solutions that demonstrate originality, individuality and innovation. Perhaps you could share your solution in order to help others who feel the same as you.


A long time ago I was made into GNU GPL cult (v3 for now), so sharing is inevitable. Although I can die before.

If the scheduler waits until a core has no work to download more WUs then what is the real loss or damage? A few seconds lost time?


It's up to four hours, as a matter of fact.


Not a problem in my mind but if you really want the red button then submit a Trac ticket and ask for it.


I see no reason. You asked for example, there it is. OTOH, I think such feature being provided would make things even worse. OTOOH, the behaviour described in the example makes problem for me (although, I don't think it's a bug of any kind; It's just a way it is). As of my problem I'm going to solve it (and bunch of others); But excuse my arrogance, I'm going to do it my way.


I am in no position to grant or deny your request.


Good. Now admit that boinc doesn't need you to fight for it.

primaboinca is on the move to some unknown equipment. Hopefully, that will fix longstanding issue of the data server running out of space. That move is planned about 2012 Jan 1. It's unclear what's going to happen at the date (either data is going to migrate or migration will be over). Fabio, we are watching you.

Meanwhile, old server is still operational. That means: new work isn't generated; timeouted WUs are re-issued; those are collected when eventually server would have some space. Don't ask, we got used to it.

1) keep all of the CPUs alloted to BOINC occupied with work
2) return results before deadline
3) over the longterm, divide system resources amongst the projects you run according to the resource shares you specify

SKIP

If you can provide an example of the scheduler failing to meet its 3 primary goals and none of the aforementioned "tricks and possibilities" fix the problem then we're interested.


I can. Although my issue was somewhat orthogonal. Just last Thursday (no, not "The Last Thursday") I'd babysat a client on three cores. Buffer is set to one day. However, for 12 hours or such client had kept buffer at something like 17Ksec (instead of 86Ksec).

My installation is somewhat weird, I understand that. I have to give network for client each four hours (via simple cron-job). Twice I suggested client to go for WUs, but in spite of having three WUs only (and one of them with estimated time some 200sec) client ignored network completely. Until one core would have been left with no WUs at all nothing could force client to get more.

So, my wish would be a button with nine red letters engraved on it:

GTFWUs NOW

OTOH, it's clear to me, any toggle that can force client to do something screws things even more.

Frankly, would not know if other devices that have the same member CPID and are associated to same profile, but not to rosetta [but do have other common projects] would adopt that profile's change.


From my observations, those setting propagate just like CPID does. I suppose limitations of CPID propagation apply here too.

p.s. Those really interested (anyone?) would just look in the code. I'm off.

BOINC is just the managing program, simply said it tells the projects science applications when they can run and which project can fetch work next. It doesn't do any crunching. So there's no need to optimize BOINC for any platform.


Here is a nearby thread where FDF experiences problems with boinc mis-detecting user's activity. He runs bubuntu. Probably, bubuntu doesn't count as GNU/Linux anymore anyway.

However deadlines of already present WUs aren't (I've moved time three hours back). You probably shouldn't do that under heavy load.


After some experiments, I've discovered that's whatever interface to client in use what localizes time (deadlines are in UTC all the way).

But, that would make system time to be UTC. That will be very inconvenient.

For those using real operating systems here comes the recipe. You should set TZ environment variable to empty value (or any unparsable value, tzset(3) has more) for boinc-client process. For debian (and nasty derivates), first stop the client; then add this line:

export TZ=''


somewhere in /etc/default/boinc-client file; then start again. Don't edit with client running -- time doesn't like dirty jokes. Users of other real operating systems probably should find more suitable way.

I've just checked. Time in logs is UTC now. However deadlines of already present WUs aren't (I've moved time three hours back). You probably shouldn't do that under heavy load.

Post:

The interesting order depends on work availability at the attached projects,


Does it mean that client has some paranormal wisdom about WU availabitility in future? Or not? I'm confused.

And a bit of observation on FIFO. Before PG challenges I nomorework every project attached except SZTAKI that has four week deadlines. At a challenge start I suspend it and WUs are finished eventually after challenge end. This time, three days before the Equinox SZTAKI stops distributing work, so I've resumed ABC in order to keep cores busy. ABC has two week deadlines, WOO-RLLs are quite time consuming, thus I decided that as soon as I see that started WU doesn't finish before the challenge end I can safely resume ABC.

So, within 48 hours before bottom deadline a client has three cores and three days of work. What could possibly go wrong? The client starts to empty the queue from the end. That was scary. Within eight hours before the top deadline three hours of work weren't even touched. Those three hours were finished and uploaded, however they weren't reported. I had to manualy report them two minutes after deadline. Hopefully they weren't sent to someone in that time.

Shortly, I fail to see any FIFO.

Sorry, I've used boinc from many times but now I've installed ubuntu and I'm go on with bonic it's all ok but sometimes I've a calculation error with primegride project and this message:


First, if primegrid application errored you, you should discuss it with primegrid stuff (AFAIK they are on vacation now, beware). However, be prepared to present more information about that presumed error. Honestly, what you show here has nothing to do with this.


chrt: failed to set pid 2171's policy: Nessun processo corrispondente
chrt: failed to set pid 2171's policy: Nessun processo corrispondente
chrt: failed to set pid 2171's policy: Nessun processo corrispondente
/etc/init.d/boinc-client: 239: cannot create /proc/2171/oom_adj: Directory nonexistent


When /etc/init.d/boinc-client (that's an initialization script) has reached its maintanance steps the process number 2171 (it was boinc client, I suppose) had already gone. More diagnostics is in /var/lib/boinc-client/std{out,err}dae.txt logs, but in /var/log/syslog

And last, but least, if you problems running stock boinc client in bubuntu bothers you then you should install from here

I presume you've messed concepts. What you're talking about is an 'estimated CPU time'. And upon attach it's unkonwn to boinc at all. boinc requests amount of work in seconds (based on your preferences). Then project server ships as many WUs that would be for the time requested (based on how it was configured, and that out of your hands completely). Configure your boinc to request minmal amount of work, decrease cache. That's what you could do, but better don't mess with boinc.

What you should check is 'report deadline'. If WUs can't finish with that time, then you clearly have a problem.

Shortly: let boinc do its thing.

Posted 18 Jun 2011 by whynot
Post:

1. On Linux systems avoid using the Berkeley installer to install BOINC. Instead you should install BOINC from your distro's repositories which installs BOINC in such a way that it and project executables run under an unprivileged user account named, for example, boinc-user. That user is severely restricted in what it can access and modify on your system so if you do get a malicious executable from a rogue or hacked BOINC project it won't be able to do much other than delete its own files.


And that really could be a way in. Since many distributions configure sudo(1) to allow the user that installed (UID=1000, you know) to get privileges without authentication (matter of darn friendliness) then such malicious application can do anything. Everything becomes that scary these days.

Networking doesn't work this way. If the host (with those suspicious connections) has no outgouing connections to those IP addresses, then your router must not let them in your network at all. That how NAT works.

But those connections are present. I believe, that some equipment on your network spits on your ethernet broken frames. That equipment, most probably, is either dieing or is broken out-of-the-box (the latter happens too, trust me). By accident, only boinc exhibits that noise; however, that doesn't mean that only boinc suffers that noise. I'd experienced something like this myself (dieing ethernet card).

I suggest you join some forum, IRC channel, newsgroup, whatever else that has somehting to do with networking and your operating system. I hope, regulars there could ask right questions and point to right tools that could help to find answers.
