Message 6675 - Posted: 16 Feb 2009 | 15:29:51 UTC
Last modified: 16 Feb 2009 | 16:19:51 UTC

Hello all,

my machine (25536) does not download GPUGrid WUs automatically.
It always requests 0 seconds of work.

Boinc-Version: 6.4.5

I have to suspend all other Projects (all of them CPU .. Einstein, Milkyway, SETI-Beta, Freehal) and do a manual UPDATE.

Then I receive 2 new GPUGrid WUs.

When they are finished, I am running dry. (requesting 0 seconds of work ..).
So I have to suspend all other projects again, and UPDATE manually to receive new GPUGrid WUs.

All other Projects request their new work automatically.

My resource-share settings are:
GPUGrid 600,
Einstein, Milkyway 500,
SETI-Beta 250,
FreeHAL 200
(BTW: Does this have any effect on GPUGrid WU execution at all?)

My preferences are set to request al least work for another 2 days.

ONE GPUGrid WU takes in average 10 up to max. 16 hrs. of time.

So, how can I make my machine automatically download GPUGrid WUs before it runs dry?

Any suggestions?

Thanks in advance for your help.

Regards,
Martin

Change to BOINC Manager version 6.5.0 ...

Set GPU Grid to 2000 share ... (based on the shares you have), or,

GPUGrid 500,
Einstein, Milkyway 50,
SETI-Beta 25,
FreeHAL 500

The actual numbers don't matter, it is the proportions ...

The problem with all versions of BOINC right now is that there is no distinction between work for CPUs and work for GPUs ... so, you have to keep the GPU Grid project with serious LTD ... then it will fetch.

There CAN be situations where you will still run dry as the back-off from GPU Grid is always 24 hours rather than the exponential that it should be ... if the server has issues you can run dry as the most you can cache is 4 spares ...

I know, this is on an 8 CPU system with 4 GPUs and my run times are 4-6 hours ...

THAT said, I have only run dry ONCE in a month (about 2 days ago) ...

Thanks for your quick help.

Unfortunately I could not manage to find the 6.5 version for Linux x64.
(Just 6.6.7. .. which was stated to be unstable)

so i tried the following on my 6.4.5.:

First I tried to set GPUGrid to 2000 share.

Nothing happend, until I suspended all other projets (for just one minute)

and i got:
-----
Mon 16 Feb 2009 11:44:15 PM CET||[error] Proposed work request 404611.799943 bigger than max 349057.745280
Mon 16 Feb 2009 11:44:15 PM CET|GPUGRID|Sending scheduler request: To fetch work. Requesting 349058 seconds of work, reporting 0 completed tasks
Mon 16 Feb 2009 11:44:20 PM CET||[error] Proposed work request 404595.273171 bigger than max 349057.745280
Mon 16 Feb 2009 11:44:20 PM CET|GPUGRID|Scheduler request completed: got 0 new tasks
Mon 16 Feb 2009 11:44:20 PM CET|GPUGRID|Message from server: No work sent
Mon 16 Feb 2009 11:44:20 PM CET|GPUGRID|Message from server: (reached per-CPU limit of 1 tasks)
-----
so, due to this error, i changed all other projects to lower shares (between 10 and 100) except GPUGrid which is now set to 500 and Freehal to 400.

Lets see.

Currently I have two GPUGrid WUs in my tasklist (as before the tests - which where manually downloaded by suspending all other projekts).
Therfore I'm currently running into the 1 Taks per CPU limit.

So I think have to wait until at least one of these WUs is finished and uploaded.

Question: When is Boinc supposed to request new GPUGrid WUs?
.. the other projekts automatically request new work when one WU is finished and uploaded ... ?

Thanks so far.

Best Gegards,
Martin

6.5.0 is also rated as "unstable" though it is the "best" version that has caused the fewest problems for the most people.

If you have been having a lot of errors you will "lose" the ability to download more than one task at a time. As you succeed in processing tasks the number will rise till you can have several in flight and 4 spares.

Even on the i7 where I have 4 GPU cores I have at most 8 tasks on hand, 4 in flight and 4 spares (sometimes fewer) ...

Thanks for the workaround, but I want to split my GPU between SETI and GPUGRID. Any other suggestions?

Set them to equal share ... or whatever proportion you desire.

At least for me, setting them at equal, or even 10 times higher for GPUGRID hasn't worked.

Ok, it is not clear to me what you are trying to do, and what the problem is that you are seeing.

Can we start at the beginning?

How much time do you want to do with GPU Grid vs. SaH?

What other projects are attached?

What else do you see?

Lets start there and try again. :)

Message 6736 - Posted: 17 Feb 2009 | 23:43:14 UTC - in response to Message 6730.

My "normal" settings are
SETI = 76%
GPUGRID = 8%
Einstein = 8%
World Community Grid = 8%
I've been running these settings since 20 January when I join GPUGRID. BOINC (regardless of version 6.4.5 through 6.6.7) has NEVER dowloaded work for GPUGRID on it's own. I have had to do manual work arounds, like suspending all other projects, and click update for GPUGRID usually 3 or 4 times before I will finally get some GPUGRID work. I have tried raising GPUGRID percent to 820 and still have to manually feed BOINC with GPUGRID work.
Below are the specs for my 5 CUDA capable computers:
#1 Intel Core 2CPU 2.40Ghz 1.98GB RAM GeForce 9600GT 512RAM Driver 6.14.11.8122
#2 Intel 2 Quad 2.40GHz 1.98GB RAM GeForce 9800GTX+ 512MB RAM Driver 6.14.11.8122
#3 Intel 2 Quad 2.40GHz 1.98GB RAM GeForce 9600GT 512MB RAM Driver 6.14.11.8122
#4 Intel 2 Quad 2.83GHz 1.98GB RAM GeForce 9600GT 512MB RAM Driver 6.14.11.8122
#5 Intel 2 Quad 2.83GHz 3.25GB RAM GeForce 9800GT 1.024GB RAM Driver 6.14.11.8122

Ok, sadly, it is not likely to do what you want with the settings you have.

The problem is that you want to stress SaH and not GPU Grid and there is no distinction in the BOINC Managers for CUDA vs CPU work though SaH has kinda a work around.

My suggestion is that you pick one system and attach it to GPU Grid, if needs be set up a specific profile for it and set the resource share for GPU Grid to 200, with BOINC Manager 6.5.0 you will reliably fetch work (well, it works for me on 3 systems reliably since december something) ... the other systems set to SaH ... with what ever configuration you want for them as far as CPU vs GPU work ...

Until there is a version of BOINC that distinguishes between CUDA and CPU work and fetches reliably you are not going to be able to get there from here ... the main problem is that you want to stress SaH and only do a little on other projects ...

@Paul: Thanks Paul for your suggestions to my initial question!
The share settings you proposed (GPUGrid very high in relation to all CPU Projects) seems to work fine.
My Machine is now running since 36 hours without manual intervention, and it automatically loads GPUGrid WUs,and also other Projects WUs.
So, I have "always" one GPUGrid WU running and one in spare.
I assume it takes some time for the system to establish this "smooth" operation after changing preferences or manual interaction. Some kind of "transient condition".
I am still on 6.4.5. which is fine with me (as it seems right now).

Thanks and regards,
Martin

P.S.: Is there any documentation about the differences between 6.4.5 and 6.5.0 ?

Thanks Martin,

I'm trying your suggestion, I have assigned two GPU's with GPUGRID, and not allowing GPU work from SETI on those two machines. I have also set the GPUGRID percentage to 820 for those two computers. I have done this by setting up a separate "location" for those two computers. We'll see if this works in about 11 hours from now. Thanks again. Rick

Yes, you have to get the LTDs and STDs stabilized ...

[quote]P.S.: Is there any documentation about the differences between 6.4.5 and 6.5.0 ?


The largest difference I have seen is that you don't need a configuration file to get BOINC to properly "see" the GPUs and to use them. With 6.4.5 you seem to need a file to tell BOINC to use the GPUs ...

The version deltas are not well maintained so it is hard to say what is in the various versions. Sometimes you can find notes on the BOINC web site's forums as to some of the builds.

But the good news is that you are up and running.

With the 9800 GT in my system I usually have one running and one or two spares. Real run times are between 12 to 30 hours ...

Yes, fortunately the settings you suggested seem to work well on my system.

Again, thanks for your help on that.

Concerning the version-documentation .. unfortunately that was my experience when I was searching the web for more info. "not really documented"
-> Maybe it would make sense to take some time to document these things in some more detail and structure. (There are some good examples for that in the GPL community)
For the time beeing I think there are "millions" of boinc-users out there asking the same questions?
.. who could be the right addressee for such things in your opinion?

Might be of interest for some Linux users:
What I experienced using Boinc-Client 6.4.5 under Linux was, that it found the GPU right after installation, but it could not find the GPU again when rebooting. The reason IMHO was, that at this point, when Boinc-Client is started during system-boot (in my case /etc/rc2.d/S20boinc-client) the native NVIDIA driver is not yet loaded. So I changed the startup-order for boinc-client to S80 on my system.
That solved this issue and works for me.

Best regards,
Martin

@ms113

Well, now that we have at least 4 major documentation sites for BOINC related material I am not sure who to call ... Ghost Busters is out of business ...

At one time before the strain killed what was left of my sanity I was the one trying to document the BOINC world, but, alas, no longer...

If it is part of the design and server side you add it to the Trak Wiki documentation.

If it is BOINC then it goes into either or both the UBW and the UCB Wiki ... and the FAQ service Faq along with all the other FAQs out there ...

The Version information it is USUALLY posted as sort of a BLOG in the BOINC web site forums (down at the bottom of the page) usually added it seems by Ageless.

Theory says that you can make the appropriate changes in most of the places by creating an account and adding the information ... I no longer own or maintain the UBW and no longer know the rules there, the UCB sites are controlled by Dr. Anderson and as he does not like my writing style I don't know the rules there either ...

@Paul

Sorry that it becomes some kind of personal or philosophic

.. but your post sounds to me like, some time ago, you asked similar questions, tried to work on solutions and conceded victory to ... whatever ...

Sorry again, but I really miss the whole foretime ...
.. what's the hindrance.

In my humble opinion, boinc is a serious projekt (isn't it?)
.. I still really can't believe that there is no appropriate documentation (and no way to establish it). Also detectable for a "simple and interested user".

I tried really hard to find answers to several, sometimes technical, questions about the project and its context (e.g. special applications ...) before asking questions in a forum.
And I was not able to find at least one reasonable source for basic technical informations about things like
.. What is BOINC responsible for vs. what are the apps. responsible for
.. changelogs (BOINC- and/or application-Versions)
.. Bugtracking

Even to find simple Downloads - I mean I could not find Version 6.5 for linux using google, boinc.berkeley.edu, before j2satx told me (above in this thread).

Maybe I am to .. whatever.

You seem to be very experienced and interested in this Projekt (talking about response and responsiveness).

I really can't fit that all together.

Regards,
Martin

P.S.: I opened another thread ("CPU Utilization varies ...") .. where I also did not find an answer yet . Maybe you can take a look.
No answer or comment since posting.
Does this mean, that my question is to stupid .. and worth no answer?
or is there no answer?

I conceeded victory to my failing heath ... I am the proud owner of enough psychological problems to keep 10-15 theripists busy 24/7 ... they however, keep wanting to send me to the neurologists as several of the symptom sets don't fit into their systems, the neurologits send me right back ... after at least 20 drug trials, none of which bothered the more serious symptoms I surrendered on that front too ... :)

The side effects were worse than the problems ... Since you asked ... :)

My laundry list includes Asperger's Syndrom (autism with high intelligence), suicidal depression, anxiety disorder, panic disorder, possible agoraphobia, possible OCD, possible rapid cycle bipolar (cycles take hours to days vs. days to weeks to months), ... and some other things ... the good news is that the autism sort of cancels the sucidal tendencies in that I have the thoughts all the time and the logical mind just considers it and rejects it as soon as it comes up ... or carefully considers all the aspects in such detail that it winds up being who cares ...

But, enough ... mental illness won ... I husband my strength and putter with my computers, on bad days I don't even do that much ...

Sorry again, but I really miss the whole foretime ...
.. what's the hindrance.


Aside from the above, the mavens that run BOINC have made it quite clear that they are not at all interested in my input or my work ... If you have the time and want to amuse yourself you can goto almost any of the really old projects and find my "footprints" all over there ... just trace back to the earlier messages and you can see ...

But there is also a lot that you cannot see ... unless you look carefully and watch over time. You also have to watch the mailing lists ... and see the responses, or lack thereof to posts ...

In many cases, serious people are not listened to, and you can decide for yourself if I should or should not be in that group. But, it is hard to get the attention of people in most projects. GPU Grid is different, FOR THE MOMENT, but so was Rosetta in the beginning ... now you are lucky to see feedback once a month from one of the project principles ...

Remember, moderators for the most part are participant volunteers ... not project paid staff ...

In my humble opinion, boinc is a serious projekt (isn't it?)
.. I still really can't believe that there is no appropriate documentation (and no way to establish it). Also detectable for a "simple and interested user".


This is a classic issue I tried to convince the "powers that be" could be easily fixed and was either ignored or told that it would not happen ...

The "best" documentation is:

- Unofficial BOINC Wiki (UBW) Old with few updates since I stopped working on it two plus years ago when I took a sabatical from BOINC.
- FAQ Service much of the same content here will be found in the UBW but this is still live, though I still question why the author had to keep his content out of either Wiki, his excuse (when he explained it to me) was that Wiki markup was too hard.
- Trak Wiki where the "design" documentation, such as it is, is kept. This also contains the rules and procedures to stand up a project. Bug reports are filed here for a more convient way to ignore them in bulk ...
- E-mail list sign up here is where you sign up for emails from the general lists ... I watch the "projects" and "Dev" lists and post on one or the other often ... rarely get an answer... :)

As an example, the question was raised on GPU detection, I did some research on the three APIs and posted a message with the results ... no acknolegement if what I did was useful, or not, though there is a hint in the latest release notes that indicates that it may have been, though there is no way to be sure ... it could also just be coincidence ...

- UCB User Manual which I think is very much lamer than what I did in the UBW because of the insistance of Dr. Anderson that the documentation of BOINC should not include any information about projects... which never made sense to me in that the whole reason for BOINC and the usual interaction of a participant with BOINC is in relationship to projects ... compare and contrast this Wiki with the UBW's treatment and decide which approach is better ...

- BOINC message Boards where information about BOINC and only BOINC is posted. This is also where the "release notes" seem to be collected.

I tried really hard to find answers to several, sometimes technical, questions about the project and its context (e.g. special applications ...) before asking questions in a forum.
And I was not able to find at least one reasonable source for basic technical informations about things like
.. What is BOINC responsible for vs. what are the apps. responsible for
.. changelogs (BOINC- and/or application-Versions)
.. Bugtracking


Think of BOINC as a game console. The science applications from the project as the game cartridges. This mind model was what I proposed before BOINC Beta ended as it is simple direct and easy to grasp. I was told I did not know what I was doing ... years later we are still trying to explain what a core client is vs BOINC Manager vs. science application.

The Core Client (aka the Daemon, there was a time when this was the official name, now lapsed again) is the "engine" that actually does the work of BOINC on your system. It is a framework of routines that allows the projects to concentrate on development of the science application and leaving all of the drudgery of the "housekeeping" to the BOINC Client. This manages the scheduling of the tasks, the running of the science applications, and the communitcations to the servers.

The BOINC Manager is just the GUI that allows you to work with the core client, that little engine that is actually doing the work ...

The Science Applications are the programs that actually do the science. Each project writes their own and they are the real point of BOINC. They are the things that take up the CPU or GPU time.

oh, and the screen savers and graphics are a separtate program provided by the project (or not) ...

The change log though the next one will likely be a different sticky later on ... oh, you have to create an account here to make it so it tracks what you have read ...

Even to find simple Downloads - I mean I could not find Version 6.5 for linux using google, boinc.berkeley.edu, before j2satx told me (above in this thread).


I always just google BOINC and then go from there... but I agree the front page of the BOINC site sucks. But, as I said, criticism and input is only welcome from some. If you are not on that list, well, ...

Maybe I am to .. whatever.


Nope, this is the classic mistake people make... I don't understand "x" so I must be an idiot ... not in the slightest. I do computers, I used to be a systems engineer specializing in the logical design of relational database systems. A specialty so narrow most people have never heard of it. Perfect for working on BOINC ... when I was in the Navy I was in electronics repair using Automated Test Equipment and as part of my duties I did technical publication review ... perfect for working in BOINC ... in the Navy and in civilian life ti also taught in technical schools and college ... perfect for BOINC ...

Anyway, back to the point. I don't know what you do for a living, but I am sure that I would not be good at it. I am good at teaching, technical writing, and figuring out systems and identifying their flaws. But, 99% of mathematics is over my head ... I asked in ABC's NC forum about the explanation of the project and you can see for yourself the same "typical" treatment of someone that does not understand ...

I on the other hand think that if there is a failure of communication it is the failure of the person WITH the knowledge when the explanation does not make sense. Interestingly enough this is this quote in the news on ABC:

There's a new developer at ABC@Home: S@NL - FilmFreak. I'll give the site a good update and add some pages about the abc conjecture.


Along with this paper which I don't think was on the site at the time I asked the questions. They certainly did not point me there when I asked ...

You seem to be very experienced and interested in this Projekt (talking about response and responsiveness).

I really can't fit that all together.


Maybe my typically long and boring dissertation will help ... if not, ask specifically, and I will try again ... I still love to teach though I cannot walk reliably ... and this is the only place (the BOINC Universe) where I can sometimes still manage to find a student that is willing to listen ... :)

P.S.: I opened another thread ("CPU Utilization varies ...") .. where I also did not find an answer yet . Maybe you can take a look.
No answer or comment since posting.
Does this mean, that my question is to stupid .. and worth no answer?
or is there no answer?


Did not see it yet, so I will go look. If I don't know, I usually won't make a comment. But the only stupid question is the one you don't ask.

Oh, and sometimes I am too down and only skim and don't speak up ... in those cases you can send me a PM or better still an e-mail ... those I am anal about ...

@Paul

Wow!
That's ... aaa... maybe the longest posting I've ever seen ..

I'm not quite sure if I could really understand the whole message behind (due to the lanquage barrier) - however - I hope so.

Thanks for the detailed references to the major information sources, it will take time to check an qualify that.

The matter of fact is, that it really seams to be - hmm - let me say "a special kind of community". Interesting.

Best regards,
Martin

P.S.: Thanks for checking "my other posting". So .. ist seems to me that there is not really an answer, at least none which someone is telling me. OK.

As my wife says: Sometimes it's better to take things just as they are!

Well, the good news is that you can print it out and spend some time with it ...

The only thing that I can suggest if you still have problems is to Skype me ... I see that you are in Europe which is not necessarily bad as I am often up in the middle of the night ... anyway, take some time, read carefully and ask questions ...

I got lots of patience ... and lots of time ...
