Hi Richard,

Is this your answer?

Remember that the NVidia detection code works in 32-bit. How much of those 6 GB, 8 GB, 11 GB was BOINC able to use in its calculations?

Could there be a flaw in that answer?

Yes, that was my answer. It was a bit of an over-simplification, but basically it's true - and it's one I happen to know a bit about.

Back in the day when GPUs with more than 2 GB of memory were first manufactured, people here noticed - and complained - that the memory values reported by BOINC were garbage. Later, I built what is now host 6910484 (originally it was on a test account, so the Host ID and creation date have changed since the first build). But the 2 GB GTX 670 is original. And I got the garbage memory size report.

Being me, I did something about it. The Berkeley staff didn't (at that time) have access to any 2 GB cards, so Rom Walton remoted into my machine (VNC!) and ran tests while I chatted with him by Skype. What he discovered is written up in commit 2882d5bc2980047ca78260dadf8e752cac0bdb8e:

Rom    10 Sept 2012
    - client: initialize memfree and memtotal before use for Nvidia
        cards.  It appears that the Nvidia API was only setting 32-bits
        of the 64-bit value.  The remaining 32-bits were whatever
        was on the stack.

So, the BOINC 64-bit code was ready to accept a 64-bit reply from NVidia code, but never got it: it's actually NVidia code which was 32-bit only at the time. 4 GB is enough for all but the most extreme of BOINC project tasks, and Rom has moved on to another job, so it's been left alone as 'good enough' for now.

Hi Richard,

Ah, now I understand. Thanks for the in-depth explanation. Looks like NVIDIA needs to step up then. ;)

I'm wondering, does that affect the card video wise? Meaning, when I play World of Warcraft, is my new card using only 4GB of it's 6GB?

Have a great day! :)

Got my Linux Mint box connecting through RDP... finally. The session defaults to Xorg, I needed to select a different session.

Unlikely, but that question is out of scope for here. I'm only concerned about the information flow from NVidia code to BOINC code - and BOINC is very low on NVidia's priorities.

NVidia pays vastly more attention to game coders - it's where they get their profits from, and that always talks - and that's why there are also frequent driver updates whenever a new range of cards or games are released. I would bet that your game knows all about all your memory.

Hi Richard,

Yeah, I understand what you're saying. Thing is though, if my wet RAM is serving me correctly, I believe N... Nope, it's not NVIDIA, it's EVGA. Never mind. ;)

There's one thing I don't like about my new card, it has Micron RAM. I remember reading about RTX cards failing because of that RAM. I just hope I don't run into that same problem.

Have a great day! :)

April fools! ;)

Yeah, besides the price, the first thing that gives it away is how to cool it. ;)

That reminds me of the greatest AF joke I had ever "witnessed". Back when the shuttles were still flying and I was still living in San Diego, Ca., a radio station I always listened to, 101 KGB FM, was running a joke. They convinced people that the shuttle that was going to be landing was diverted to Montgomery Field in SD because of weather or some such. I knew that the shuttle needed a runway about 20 times longer then Montgomery's is. They had several hundred people up there to watch the landing. :)

Have a great day! :)

Greetings,

I'm attempting NOT to have a boatload of ghost WUs on my Linux box like I have on my Winders PC before I have it read my "new" app_config.xml file. I have BOINC set to No New Tasks and have been running them down for some time now. BOINCTasks told me at about 1PM Central time yesterday that it will take almost 10 hours to finish. That would have made it about 11PM last night. It's still working to deplete my cache with just "over an hour" left to go. Is there a reason that BT is so far off on it's estimations?

Have a great day! :)

What did the Boinc manager say, as I feel sure BT gets the info from Boinc, wouldn't make sense otherwise.

You probably filled your cache while blc23 tasks predominated. The BOINC system (primarily on the server) will have adapted your estimates to their shorter running time. If you've now got mostly blc36 tasks to burn off, they will be running slower than expected and will take longer to clear.

Hi Bernie,

Although I used BOINC Manager to initially attach to SETI while on the box, it no longer makes a connection to the client. This is Linux and it works "differently" than Winders does, I think. So I never use BM to check on the client. Nor do I on my Pis either.

Have a great day! :)

Hi Richard,

Ok, yeah, I got a boatload of blc23 tasks. I went through my list here and checked about a dozen random WUs and they were all blc23. Right now I'm down to my last WU. :) It'll be done in about 5 minutes. :)

Thanks and have a great day! :)

Hi Siran

I was out all the week, so probably i miss something , i see now you have Linux cruncher running.

Why you not try to run with the Tbar/Petri special sauce? They are a lot faster than the stock ones.

Just curiosity

Hi Juan,

I'm not sure where to get it. I did get a couple old ones and I have no idea how to use them. I looked at the readme files, but most of it is command line option explanations. If you have a link to it, I'll let you know if I downloaded it or not.

Have a great day! :)

Greetings,

Now what?!?

I type in the command to read the config files and this is what I get:

$ boinccmd --read_cc_config
retval -155
Operation failed: authentication error

So I figured I needed to do "sudo" and got this:

$ sudo boinccmd --read_cc_config
[sudo] password for rick:                 
retval -155
Operation failed: authentication error

Doing this is so much easier through BOINC Manager. :|

Have a great day! :)

Siran

[edit]
Figured it out. I had to change to the working directory for the command to work. Now I get "retval 0"
[/edit]

[edit2]
THAT did NOT work! I still get a boatload of CUDA60 WUs. Don't tell me, after reading the config files I had to restart the client. That cannot be right though, but I wouldn't doubt it to be the case.

I'm not sure where to get it.

I use our team server to DL the packages, so the link i use will not work for you.

Someone could post the link to DL the Tbars all-in-one builds, please ?

Thanks

Greetings,

In my investigation into trying to figure this out, (why I'm not getting SoG WUs), I discovered that /var/lib/boinc/cc_config.xml and /var/lib/boinc-client/cc_config.xml are symlinks to /etc/boinc-client/cc_config.xml. Let me know if I'm wrong, but it looks to me as though/var/lib/boinc/app_config.xml and /var/lib/boinc-client/app_config.xml also need to be symlinks to /etc/boinc-client/app_config.xml. I have since placed app_config.xml in the /etc/boinc-client directory. I need to know how to create a symlink. More investigation...

Have a great day! :)

Hi Ian,

That is one of them that I have. I haven't unzipped it yet. I shall do so and read anything in it. I will deal with that when I, once again for the third time, empty my cache of CUDA60 WUs. Thanks Ian. :)

Have a great day! :)

You shouldn't have to mess with symlinks. But you can always Google symlinks to read up on how to create them. Pretty simple. You need to finish all you repository version of work and remove the repository version of BOINC before you start using the All-in-One. TBar says the repository version always causes issues when trying to upgrade to the AIO. You might want to first move the repo location of BOINC to /home first and take possession of it away from BOINC:BOINC and change to you as user. Makes things so much simpler if you are the owner of the directories and files.
