THANKS YOU Richard !


I'll try to live up to her high standards.

Hehe, bah it s not just a question of stardards, but in my case, a question to explain with simple words and simple figures.

you made very very well i fully understood you what you meant :)


Actually, neither of the applications uses the Open Graphics Library (OpenGL). They both use the Open Computing Language (OpenCL): and you are right, OpenCL is implemented on both the ATI and NVidia platforms.

Ya sorry, those 2 words are so looking the same ^^



control part of the program (running on the host CPU) has to be different.

so it will make it fail ? :(

Cant wait the other is ready. because doing AP on CPU i always found it silly and doing a 8hrs-12hrs-18hrs task on a core.. i will never accept that. Sorry



Correct. Carry on using that until the dust settles on this rollout, and you are ready to choose which applications you wish to run. The updated application to run AP (the new version) on CPU is the only benefit you will find in the new installer.


alright, gotcha
i still hope you will do a 0.40a or 0.41 installer with the real Nvidia AP6 one inside. :)

THANKS YOU so much Richard, for your clear answers :)

LOL, just around the time that the new science applications are being released, do I get one v5.05 AP. I haven't had one in over 6 months. Serious coincidence. ;-)

Shhhh. Don't shout, and wave it about, or the rest will be wanting one too.

I got one on my GTX-460 machine, only because I have the older Nvidia AP app on it.

Why does the installer not insert <flops> lines?

Because, eventually, they'll fix the DCF problem. Then there'll be all sorts of hell involved with WUs timing out etc.

Because it's still in Alpha testing and isn't good enough to be put in the installer yet, when the 100% CPU Bug has been fixed and it's fully thread safe then it'll be in the installler, and not a moment before that.

It looks like SETI V7 is out. Splitters are running, cricket is maxed, and at the same time "old SETI" workunits out in the field on the stats page is slowly sinking.

I guess this means that everyone running the Lunatics apps should prepare to panic! We won't be getting much new work until we get some new apps!

Unlikely since there is no v7 apps listed on the applications page, more likely a combination of Astropulse v6 and a shortie storm causing the cricket to be maxed out and the status page to show minimal MB tasks ready to send.

Hmm... I'm not seeing any shortie storm on my computers, and the result creation rate is low...

Nothing to do but wait and see, I think.

Well, a nice "old apps" comparison with comparable hardware.

Chapeau.

You can expect a few more % from AP v6.01 r555/r557 and some 20-25% extra if you have AVX ;)

Message 1209380 - Posted: 23 Mar 2012, 20:47:35 UTC

Can anyone tell me what happens if an app_info.xml get removed/corrupted without it being uninstalled or the project reset?

Will Boinc simply revert to using stock apps if it cant find the app_info file or will it go bonkers and error out any WU in the cache?

Cheers,
Cliff,

I tried that at first. Just simply deleting it doesn't really appear to do a whole lot. Deleting the EXEs that were described in the app_info really annoys BOINC and it then tries to re-download them.

What a project reset does is goes into client_state and basically purges everything except host-specific stuff (computer ID, account, etc).

I cleared it out manually by going and finding the two or three entries in client_state that referenced r409 and just simply removed them. Once I got assigned a new v6 AP, all the needed files were downloaded automatically.

On hindsight, since I did all of that with an empty cache, hitting the reset button would have been really easy. I believe it gets slightly (and I do mean ever-so-slightly) trickier when going stock->opt. Do the app_info and put the new EXEs in the right place, and then delete the stock ones, and it's -supposed- to figure it out and keep going.

edit: Realized I didn't exactly answer your question. As I was told earlier in this thread, if you just simply hit the reset button, tasks that were partially-crunched and ones waiting to run will be purged. You -should- get them re-sent to you, along with the stock apps.

Right:-) What concerned me was that Vince got hammered with a nasty the other day, and it occured to me that if some rootkit or other nasty gets onto a rig who knows what it screws up, moves or simply deletes.

And I do a fair bit of sniffing around the web..

Methinks a backup protocol for boinc is required.. even if its just the app_info and exes, and an archive of the sub dir that the lunatics installer puts the stock apps in. Just in case.

Regards,
Cliff,

Most rootkits won't give a damn about your BOINC data directory. Not unless someone with a BOINC hatred writes one that specifically attacks BOINC data directories, do I think you need to worry about anything. If you want to backup BOINC, backup the full data directory, with all sub-directories and files.

Else, BOINC has built in redundancy where if you can't return the work, it'll time out and be sent to another computer which will do the work instead.

And if your system does get compromised in some form or way, after you cleaned up the mess, you can usually just reinstall BOINC and continue where you left off (due to the work being in the separate data directory). Having the data directory live on a disk or partition separate from your Windows partition is without doubt the best solution. Then only a full drive fail will break your ability to return the work.

I do something like this during my nightly backup schedule. My data directory resides an a separate physical drive from the EXEs, which are on the system drive. The backup includes an image of the system drive and all of the data drive except the projects, slots, & symbols folders.

By the way does anybody know if David has had a chance to look at the GPU zero results problem?

Even easier than that. Place the app_info. Place the new exes. Restart BOINC.

No need to delete anything. On Windows, you could even get the Lunatics Installer to do all three steps for you, including - from next week - the apps for Astropulse v6..

Do you mean the 'zero credit for results' problem that was holding us up?

I'm just looking at changeset [trac]changeset:25484[/trac], posted half an hour ago:

scheduler: fix bug that could cause zero credit for the first few jobs of a new application
(in wu_estimated_pfc(), only multiply by app.min_avg_pfc if it's nonzero).

That sounds like the one, with a plausible resolution.

Hmmm, now, not impressed. Had two of those AP v6.01s and they both ran for all of 2 seconds. What's the use of downloading 16MB worth of data that runs all together 4 seconds, less even when you count CPU time (0.39 + 0.41 seconds)? ;-)
