21) Message boards : Number crunching : app_config.xml - the bit (Message 1516323)

Thanks Guy.
I'm kinda relieved to hear <app_version> isn't the way...
For your interest; my HD6950's crunch 3 x 7.03 each quite happily while a 7.00 CPU app is crunching as well. The curious thing about this set-up is that 75% of my CPU cores are utilised - despite having set the local client to use 50%, or one core.
Well, at least I know I'm not going to be barking up the wrong tree. So thanks.


And thanks for other answers/suggestions tendered. It's a lot to digest but I'm still looking for a 'breakthrough' for when the 6.06 apps start up! Or a rare 6.01 CPU app!!
If I 'balance' my set-up I'll post.

Thank you all.

Guy

Hello,
I'm looking for explicit examples of how to use <app_version> in app_config.xml
I have two HD6950's but only a dual core CPU. So in the interest of 'keeping one CPU core free' I need to control which CPU apps run depending upon which GPU apps are running.
Is <app_version> even the right approach for this fine control?
Anyone help please?
Thanks.

14.4 all good with two HD6950's and a dual core Opteron!

Hey! It's my 15th anniversary in two weeks! Yaaay!

Yeas, everything was erroring! I was using the 4.01 Lunatics apps with no problems until a few days ago on this system*. Followed the advice given out for similar issues, and reinstalled the 4.01 but no joy. So I'm now back on the stock apps which are 'dueling' OK.

*Windows 7 64 bit.
Opteron 185 + 2x HD6950.
185 has 1 reserved core.

I expect I mean direct control of GPU usage i.e. running two or three WUs per GPU. The app_info.xml file that can produce this kiind of activity in my system is tough to re-author every time the stock sci-apps change; it would be nice to see a "How many do you want to try to run per GPU" option in the settings.
Thank you -

Hello,
Are we gong to see a GPU utilisation factor in the stock SAH settings anytime?
Thank you -

Hello,
Are there any command line parameters for the stock CPU app 'setiathome_enhanced 603'? I ask because - during the seti servers maintenance I ran out of gpu work so only a '603 was running. It was spread out over both cores. Maybe it runs faster this way? In which case good. But I thought it'ld be a good idea to constrain the app to one core.
Thanks -

That is very kind of you to cobble that up. It works a treat!

The GPUs - when they have the full attention of the CPUs - crunch 6.10 apps to around 75% of their capacity, and without that un-nerving CPU overhead. When the CPUs are occupied, with 6.03 apps, the GPUs still manage a healthy 55%. That's great. It's going to be fun experimenting with balancing the power.
Initial observations are showing lightning fast GPU work!

Thanks very much,

Guy

Thank you for the hints -

Let me make it clear - the

AP6_win_x86_SSE2_OpenCL_ATI_r1812.7z
MB7_win_x86_SSE_OpenCL_ATi_HD5_r1817.7z

I mentioned in the above message are not the executables - they're the compressed files found at: Update for ATi MB&AP GPU apps.
Also my CPU is an AMD Opteron 185 (2.6GHz, pni - SSE3 capable...)

***

OK -
I've jumped in. Only to find the same behavior as before - lots of CPU activity but almost no GPU work registering on 'GPU-Z.0.7.0.exe'. I think GPU-Z may be failing to get through the new Catalyst 13.4 drivers because it looks like the Astropule WUs are only going to take about 2 1/2 hours each.
Is that about right for

ap_24jl11ad_B1_P1_00331_20130511_27868.wu
ap_23ap11ab_B5_P0_00368_20130511_31436.wu

on a pair of ATI HD6950's? Or is it the CPU making a meal of them by itself?

***

The message:

 12/05/2013 06:50:32 | SETI@home | [error] State file error: missing application file libfftw3f-3.dll

was reported despite the DLL existing in

 C:\ProgramData\BOINC\projects\setiathome.berkeley.edu

And

 12/05/2013 06:50:32 | SETI@home | [error] State file error: duplicate app version: setiathome_enhanced windows_x86_64 603

- maybe because I wove in Claggy's CPU only 'app_info.xml' example file?

***

The existing WUs were grabbed by the Optimised MB app, thus -

 12/05/2013 06:51:02 | SETI@home | Starting task 08oc11af.7014.8250.5.11.181_3 using setiathome_enhanced version 700 (ati_opencl_sah) in slot 1

But all produced errors, for example -

 Status                 Run     CPU     Credit  Application
                        time    time 	
 ----------------------------------------------------------------------------------------------------
 Error while computing 	5.71 	2.30 	--- 	SETI@home Enhanced Anonymous platform (ATI GPU)


The 700 in the line above above is simply the number I put in the 'app_info.xml' file:

.
<app>
    <name>setiathome_enhanced</name>
</app>
.
<file_info>
  <name>MB7_win_x86_SSE_OpenCL_ATi_HD5_r1817.exe</name>
  <executable/>
</file_info>
.
<app_version>
  <app_name>setiathome_enhanced</app_name>
  <version_num>700</version_num>
.
.

- because of the MB7_win_x86_SSE_OpenCL_ATi_HD5_r1817.exe name of the executable. Does the <version_num /> have any real effect? Or just cosmetics...

***

Despite the 'duplicate app .. 603' conflict, BOINC dloaded a few version 6.03 MultiBeam WUs and assinged them OK -

 12/05/2013 06:50:53 | SETI@home | Starting task 28my12ab.18293.106923.10.11.206.vlar_2 using setiathome_enhanced version 603 in slot 3

- with an estimated 15 hour ttc.

Again - I'm not used to seeing WUs take so long. With Cat 12.8, an AP would take about an hour and an MB between 2 - 7 hours... Am I looking at a new set of 'longer' WUs?

Thanks -

Elaboration: (for Windows 7)

app_info.xml - I see that lives in

C:\ProgramData\BOINC\projects\setiathome.berkeley.edu\

And so, if I'm using the two Lunatics optimised apps -

AP6_win_x86_SSE2_OpenCL_ATI_r1812
MB7_win_x86_SSE_OpenCL_ATi_HD5_r1817

- is it wise to have app_info.xml recognise the 'stock CPU' apps? I presume, to continue processing the WUs I already have. Or does the Optimised MultiBeam app process these WUs? (cool)

Thanks -

That's encouaging, chromespringer.
My problem is - ignorance. I've not used optimised apps before. Reading about how to set it up is like chasing your own tail - the information is often oudated and strung out thinly over many domains.
I would be happier to test a few configs if I had the confidence: I could loose the WUs already here when it (the config) is done incorrectly.
One of the basic pieces of info I'm in conflict about is the name of the config file to create, and where. Clearly, it's up to me to find out what to put in it. But help in any of these areas would be gratefully received.
Thanks -

Ah, that's interesting, Mike.

So. Is it safe to install these new Apps while I have CPU tasks in progress?

11/05/2013 07:20:35 | SETI@home | Starting task 09oc11ad.31898.7192.3.11.130.vlar_0 using setiathome_enhanced version 603 in slot 1

I have nothing on the GPUs so that App is going on immediately! Or not...?

Thanks

Is it just me - I'm not getting any GPU Applications after upgrading to Catalyst 13.4 - Well, I did get some Apps for a while but they took so long to compute. And looking at various 'resource' monitors I found the CPU was working very hard and the GPU was processing intermittently and not much when it did.

So before revert to 12.8... Are there any GPU Apps available at the moment?
I mean - Or has the project decided my new driver augmented GPUs are not worth sending out for?

Much obliged.
