Hi Steve, based on that description and log I'm thinking you're also hit by this?


Well no. What I was hit by was a large concrete block of stupidity on my part. I thought I'd enabled virtualization, but I had not. Pays to double check eh?

No need to detach and reattach, WUs sitting there quite happily while one of them crunches on. So far, so good.

Thanks Marius!

Fun fact, it might have taken me significantly longer to fix this (pretty nasty) compute error had I not run into this thread and had that guy not answered his own question three years after posting it! Thanks, wherever you are!


OK. Terrific!

So having read this I thought I'd try a brand new Windows machine.

The experience was like an episode of Twilight Zone.

I downloaded 24 tasks. So far, so good.
I suspended all the other CPU projects because I am impatient like that. One C@H task started with all 4 CPU cores. So far, so good.
Now things start getting weird...
First all the tasks are marked "Postponed: Please upgrade BOINC to the latest version". You what?? I'm on 7.6.22!!
Additional weirdness is all the tasks in BOINC have between 5 and 7 seconds elapsed time.
Then I figure I'd look at all my tasks here. Apparently all 24 are in progress. Hmm. What about that task that was in progress (at least 3 minutes). I check BOINC but I have only 23!!
I wait a few minutes, still 23 on BOINC, 24 in progress. Weirder and weirder.
Eventually #24 shows up as Error while computing (apparently 10 minutes of that)
Here it is: http://www.cosmologyathome.org/result.php?resultid=36322953
I'm still bamboozled as to the Latest Version of BOINC.

FWIW: System is Win 10 + BOINC 7.6.22 + whatever Vbox version comes with it from the download page.

All tasks fail on my Linux box with "process exited with code 1"

This suggests some library problem I think. I'll try on OSX later.

Post:
As of right now the camb_boinc2docker application is no longer in beta, meaning everyone will receive these jobs by default unless they have specifically chosen not to. Please read the FAQ and don't hesitate to post on the forums if you run into issues. Thanks everyone and happy holidays!


I see that the beta tag has been removed in the Applications list. However, it seems the tasks still report as beta and no non-beta tasks have been recorded at WUProp:

Any ideas?
5) Forums : Technical Support : slow gpu (Message 20639)
Posted 15 Dec 2015 by Profile Steve Hawker*
Post:
My gpu(nvidia gtx 680) run too slow(only~50% normal speed) when i running to camb_boincc2docker. What is wrong ? If i run lhc,einstein or camb_legasy , nvidia works normally.


It sounds to me like you need to assign a full CPU core to your GPU. You can do this by a number of methods. The easiest might be to reduce the number of processors used in BOINC Manager preferences.

computing preferences >> processor usage

In the box for "On multiprocessor systems, use at most" put the percentage that uses all but one core. So if you have an eight core processor put 87.5%, a four core 75%, etc etc.

If that doesnt work, you can force camb_boincc2docker to use all but one processor. See http://www.cosmologyathome.org/forum_thread.php?id=7346&postid=20620#20620. Change avg_ncpus to meet your needs. I use it to make C@H use just one core but I'm running lots of other stuff too.

If you still have a speed problem then it isnt anything to do with C@H.

As the title says.

It's great this project is alive once more and with OSX support to boot. Encouraging to hear you are considering badges - please dont bother with the rubbish RAC badges the BOINC server provides. No-one cares about those and they do NOT keep people crunching.

Apart from credit milestone badges, the single best thing you can do is to dump CreditNew. This sorry excuse for a credit system has destroyed projects in the past and you dont want that.

Use a fixed rate or a variable rate but dump CreditNew. If you don't you'll find all the credit chasers will have left. You can argue "but science!" yet the credit chasers wont hear because they are gone. Unfortunately this group tends to have the biggest collections of cores, so you'll be losing a ton of processing power.

The Lattice Project had CreditNew and took much too long to replace it. They dont have any crunchers now, so their results dont justify the expense. That could end up with their university pulling the plug. And you dont want that either.

Dump CreditNew and it will be the best day for the life of the project.

Well, whatever you did worked.

I now have validated tasks on my Mac. W00t!!

Strangely, it pays much better than my Linux box which has a more powerful CPU.

Ah well...

Marius,

Great news!

Might I suggest you place a notice in the newsfeed - not everyone reads the forum.

Pleased to see OSX tasks at last. Managed to download some.

They all end up with validate errors. I have no idea why. VB runs fine on other projects.

Please help.
