1) Message boards : Number crunching : GPU max 100wu Why? (Message 1980114)

Post:
Very intresting reading. Thank you all.
If I'd know that it was this big issu with databas servers keeping track of very many(ALOT) of wu's was the problem. I guess I would have been silent.

My suggestion to decrease the number of Wu's would be:

For very fast GPU's : 10hour per wu
Medium cards ; 1-2 hour per wu
Slow cards : 30 mins per wu

I guess there is problems here with my suggestion regarding cpu use and similiar size for wu.

But my suggestion would maybe solve 1 bottleneck a little.
And make the wu's bigger. The size doesn't really matter as they say *haha*.

I guess this will also be a problem for servera that create the wu's.

OpenCl Programming for fast GPU's might work for the creation of very large wu's somewhat faster.

As of now I leave it up to the guys that needs 900 000 USD to see if my suggestions are of any use.

Oh, and I will tell my mom that I can't make the setting 100 to 200 because SETI lacks 900K $ *And it is true. She asked me that today of FB and she has a win 10 with a NVIDIA 1060

Post:
From what I remember, the 100 Wu limit was imposed because after the outage (any outage in fact) the database was unable to keep up with the large amount of results being returned in one go.

So in fact now that GPU's have got faster and there are many multi GPU machines it would probably be even worse, add in Linux and the special sauce and well..

Someone should do a few sums on how many WU's the top 100 machines process per hour, times that by the nominal length of an outage an see what total number of WU's being returned from just the top 100 would be.



Then maybe the restriction should be in how the results are returned instead of not sending new wu's. Maybe just 50 or 100 at a time..... Not all....

I know that the setting to 100 wu max was done sometime because the servers supply was drained by some people.
But that was a long time ago and if i remember correctly it was before the servers where co-located to different site.

Now with the alot faster GPU's and better servers and better internet connection it should be possible to increase the setting 100 to 150, 200 or maybe even more.

Is there any chance that the number of wu's per GPU can be increased to like 200??
With the faster GPU's they get without wu's when there is server maintanaince and server downs.

I suggest an increase of wu's per GPU!!

Post:
no surprise to me.
With r_3500 you are using _period_iterations_num 3 and with r_3584 you are using no app args.



I added -period_iterations_num 5 -hp now....
See tomorrow how it looks.
Thanks...

More strange questions from me....:)

I am running MB8_win_x86_SSE2_OpenCL_ATi_HD5_SoG_r3584.exe from Mike's site.
ATI 5850 card...

I can't really see any difference in speed when using that SoG one or ATI_HD5 .r3500 version(i think it was from lunatics).

Am I doing anything wrong, missed something or is the apps about the same speed for ati 5850?

-------------------------------------------------

In boincmanager I see under /Tasks/program it says: lokal: setiathome_v8 8.22 (ati_opencl_sah)
In windows task manager it says i am running "MB8_win_x86_SSE2_OpenCL_ATi_HD5_SoG_r3584.exe"

And in app_config.xml the line:
<plan_class>opencl_ati_sah</plan_class>

If I look the same place for nvidia card it says: setiathome v8 8.22 opencl_nvidia_sog

But since I don't master in programming I have no clue if both is ok Nvidia and ati

Link to ati computor.... if needed.

The version on mikes page is the same as stock v8.22
good.

thanks for answer.

I found one ATI HD5 SoG .r3584 at mikes page....
I'll try it on 5850 and see how it goes....


And I now see that it is v8 8.21
Anyone has a v8 8.22 around somewhere?

Thank you for answers.
I'll keep 1 free core for app. I thought it might be driver issue or something else.

Where can I find app for ATI_HD5-SoG??
I want to test it on my 5850's before I retire them.....

5850 is using stock app and is if I'm not mistaken only using ordinary ati apps not ati hd5
I've been successfull in running lunatics .r3500 ati hd5 app for a year now, without problems.

It is using 1 core almost all of the time.....

boincmanager 7.6.33
NVIDIA GeForce GTX 1060 6GB (4095MB) driver: 376.33 OpenCL: 1.2
Win 10 home and an GenuineIntel Intel(R) Core(TM) i5-6400 CPU @ 2.70GHz [Family 6 Model 94 Stepping 3]
(4 processors)

I am running stock "SoG" app

Any idea......?

One does not usually compare credits between projects....
All projects value the work done differently.

You can compare your computor to a similiar one here on seti to see if your computor are doing as good as it should.

I'd say your computor does what it should here on seti.

Post:
Set NNT and complete all other tasks, then remove your SETI account from that machine, give it a short while then add SETI again, you may wish to reset NNT until you get machine set up as you require.

I use this method to remove ghosts and accumilated old files in CPND.



Thanks Kevin. It didn't work with seti...
I probebly need a new install of Boinc for it to work.
New boinc then new seti and i most likely get a "new" machine in SETI website.
Then after Mars I can log in to my setiathome account and choose "merge computors.

I might try that later today.

In BOINC just highlight the tasks you don't want, and click "Abort"

They will be released and resent to other users.


The tasks isn't in boincmanager only at setiathome site...

I reverted back to running seti ati ap tasks and installed .e2942 ati ap app after removing old v8 app.
I let boinc read the local config file and config files in boinc manafer.
And after watching an episode of Farscape I saw that boinc has dl 100+ of the old v8 app tasks. I forgot to restart boincmanager to initiaise propery on this machine.... Os there any swift way to get rid of the v8 tasks so they doesn't remain until deadline which happens to be some day in Mars?

Sounds smart and is also answer to my question.
Thank you.



How can I tell if an app is Apha or Beta?


You just would not see alpha unless your hacking abilities good enough LoL
Alpha releases are closed ones and not going to be published in anonymously accessible parts of internet.

may I remind all and sunder that ALL GPU apps are still in ALPHA?

that means IF you run them you need to pay VERY CLOSE attention to your hosts and report invalids and inconclusives that look like they will go invalid. Alpha apps are very likely to still have problems. Only when they have been promoted to beta the dev is fairly certain they are good. (and sometimes not even then).

IOW when you run an alpha app you need to be aware that you are TESTING it.
When you have the hood open on the car, you wouldn't let your kid behind the wheel, now would you?
Just running an alpha app is irresponsible. You might as well give the car keys to your kid when you are not sure the brakes work.

I don;t want to discourage people to alpha test. I just want to make sure you know exactly what you are doing, why you are doing it and what you need to look out for when doing it.

Well, for reason unknown i couldn't get a singe wu to dl on beta so i tried app on main.
Same with my ATI cards..
I've been monitoring them all day and so far not a single problem detected.

I'll give them(.3314) a try at Beta tomorrow again. It's getting late.

Just to be sure i enabled all 4 cores for gerasim project.
And the SETI NV app used the 0.04 core it was said to use.
No problems detected on my box.



I tried the MB8_win_x86_SSE3_OpenCL_NV_r3310 app on my GTX970 but it seems to hog a CPU core as well


Yes they do like the CPU cores don't they, lol...

I don't have that problem on my 560ti and app is smother then any other app i've tried. Only uses a fraction of the 2 cores that is freed. Here it looks ok.

driver 353.62


I tried the MB8_win_x86_SSE3_OpenCL_NV_r3310 app on my GTX970 but it seems to hog a CPU core as well. Any info on that?

Is there going to be a Cuda app in the near future?
