I didn't know that the Milkyway server send tasks to outdated version numbers in app_info.xml file.


If you use an app_info.xml file, you MUST observe what your PC do.
If you use an outdated app you will 'destroy' all tasks
(maybe also the science?).


(Currently it's the only way for members with newer AMD hardware to participate here.)



You could use the first entries in my thread without GPU cmdline settings:

This should work.

After you could decide how much % CPU the GPU app get (this don't set really the CPU usage of the GPU app, it help to let free/idle a few % CPU):
<avg_ncpus>1</avg_ncpus>
<max_ncpus>1</max_ncpus>


1 CPU-thread for 1 app/task
0.5 for 1/2 CPU-thread for 1 app/task (2 apps use 1 CPU-thread)
0.34 for 1/3 CPU-thread for 1 app/task (3 apps use 1 CPU-thread)
...

From my experiences, the CPU should a few % idle. (If not the GPU app calculation could stand still (not feeded from the CPU) and this result in a task error.)


And how much tasks simultaneously on the GPU:
<count>1</count>

1 = 1 app
0.5 = 2 apps simultaneously
0.33 = 3 apps simultaneously
...



And after you could test the cmdline settings (until now I found these, I don't know if there are more):

  • --non-responsive
  • --gpu-target-frequency N
  • --gpu-polling-mode N
  • --gpu-wait-factor N
  • --process-priority N
  • --gpu-disable-checkpointing



Until now I saw no 'officially' statement about these settings/what they do.
If you like, then use them carefully (after testing).

Milkyway updated the 'Milkyway' apps from 1.20 to 1.36.

Have a look in my/the thread, Message 64939.

If you have an app_info.xml file in the project folder, you need to update apps on your own. It don't go automatically.

In your case, if you don't get new tasks, compare the versions numbers (or apps) in the app_info.xml file with the versions numbers of the currently available apps here (or look to their creation/release dates).

I read a lot in the forum and found that the GPU apps can be fine tuned.

I found:

  • --non-responsive
  • --gpu-target-frequency N
  • --gpu-polling-mode N
  • --gpu-wait-factor N
  • --process-priority N
  • --gpu-disable-checkpointing




On my both PCs I use currently:
--non-responsive --gpu-target-frequency 1 --gpu-polling-mode 0 --gpu-wait-factor 0.01 --process-priority 4 --gpu-disable-checkpointing

[and on the/my FuryX: 3 WUs/GPU - GT730: 2 WUs/GPU
At SETI just 1 WU/GPU possible (on FuryX) - if more tasks/GPU simultaneously invalid results or computation errors.]



BTW.
Still with Crimson 15.12 (1912.5 driver included).
From my experiences the 'best' driver so far. Although with a downclock bug on FuryX. Either after a few minutes or a few days one or more VGA cards downclock continuously - just a reboot help.
I tested all (also Beta/Hotfix) up to Crimson 16.3.2 and Crimson 16.7.2 (Hotfix? but WHQL?)
16.3.2 invalid AP results at SETI, 16.7.2 (July/19) frozen VGA cards.



I don't know if this are the 'strongest/fastest' possible settings - and maybe it could be counterproductively...?

Is somewhere an overview with explanation of all possible cmdline settings - and how to set them?
If not, it's possible to do this (maybe sticky thread in Number Crunching)?

('milkyway_separation__modified_fit' part(s) still needed, because old resends around.)



The FuryX PC have two Xeon CPUs, 6Cores/12Threads each, but HT off for faster GPU app calculation, so in whole 12 CPU-Cores available.

With this above app_info.xml file entries:
2 CPU-Cores for GPU app support
10 CPU-Cores for CPU tasks

With this settings the whole PC use ~ 1,100 W at the wall plug. But no problem, the PC have a 2,000 W PSU.
At SETI it was ~ 850 W.
The GPU temps are higher (~ + 4 °C) and the (PC-)room hotter - ambient temps currently 38.5 °C. :-(

With this settings, it looks like ~ 10 seconds / GPU task (theoretically).
The tasks last ~ 30 seconds, but then are 3 tasks finished.

It's really a hard work for BOINC to feed the PC with enough tasks for 24/7. :-( and ;-)



If someone have also a FuryX VGA card, you are welcome to write here also in this thread to share your experiences.



Thanks.

Jake...


Maybe one day an Intel iGPU OpenCL Milkyway app will be released?

NVIDIA and ATI/AMD OpenCL apps are available - it would be a big deal to 'translate' it to Intel iGPU?

I have an Intel HD Graphics (no number ;-) iGPU in my J1900 CPU.

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

BTW.
I read a lot in the forum and found that the GPU apps can be tuned.

I found:

  • --non-responsive
  • --gpu-target-frequency N
  • --gpu-polling-mode N
  • --gpu-wait-factor N
  • --process-priority N
  • --gpu-disable-checkpointing




On my both PCs I use currently:

BTW. Is the milkyway_separation__modified_fit part superfluous now, so I could delete this part in red (and this two apps)?

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

I made a forum search because of the project prefs point:
Frequency (in Hz) that should try to complete individual work chunks. Higher numbers may run slower but will provide a more responsive system. Lower may be faster but more laggy.
default 60 (corresponds to 60 fps)


It looks like just the outdated Milkyway 1.20 ATI app used this settings.
The currently Milkyway 1.36 ATI app don't use it. I set '1' (one) but the app use/show:
Using a target frequency of 60.0

Is this OK, or a bug?

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

I'm a bit disappointed that a project task last ~ 16 seconds with the Milkyway 1.36 ATI app on one FuryX VGA card (1 WU/GPU).
I looked to other PCs, e.g. hostid=590597 with 'R9 200 Series - Hawaii' VGA cards. This VGA card have just 44 ComputeUnits (CUs) A task last ~ 15 seconds.
The/my FuryX have 64 CUs. But a task last ~ 16 seconds.

Is there something wrong - possibilities to optimize/fine tune?


Thanks.

So I guess the BOINC server software will remain 'old'?


I have inter alia four AMD Radeon R9 Fury X VGA cards and it's still not possible to get work, if the project is 'stock'. I need to use (the following entries and apps are correct?) an app_info.xml file.
(One day (soon?) it will be possible to get work without app_info.xml file?)

I don't know if the:
milkyway_separation_1.20_windows_x86_64.exe (17-Jun-2013)
milkyway_separation_1.20_windows_x86_64__opencl_amd_ati.exe (17-Jun-2013)
- are the correct, or they are Beta apps (at least they are available in the Milkyway/Download folder).

If I look (+ed correct) to the stock Milkyway PCs, they have running (the outdated?):
milkyway_separation_1.00_windows_x86_64.exe (08-Feb-2012)
milkyway_separation_1.02_windows_x86_64__opencl_amd_ati.exe (10-Feb-2012)


So it would be good if one of the admins could/would jump in this thread... ;-)


BTW.
On my FuryX's the v1.20 app is running well.

- for just 1 project task on 1 GPU.
(AFAIK, the 290/390/Fury series VGA cards can do with the currently drivers just 1 task/GPU. But it looks like no problem for Milkyway, because the GPU Load is at maximum.
I tested Crimson 16.3.2 and still just 1 task/GPU (at least at SETI@home). But I need to use Crimson 15.12, because with 16.3.2 my FuryX's make invalid AstroPulse results at SETI@home.)

I have my PC running since October last year.
Dual Xeon CPU Board with four AMD Radeon R9 Fury X VGA cards.

I added Milkyway in BOINC but my PC got no tasks for the GPUs.
I searched this forum and read the Milkyway server software need an update for to send tasks to the 'new' 290/390/Fury series VGA cards.

The FuryX is available since mid last year.
9 months later - and still not possible to get work?
The admins don't want the performance of the 'new' 290/390/Fury series VGA cards?

Up to the time the Milkyway server will send tasks to the 'new' VGA cards automatically - it's possible that the admins make a sticky (just read & closed, no new messages possible to write) thread in this forum with instruction how to set up an app_info.xml file with all CPU & GPU apps?

I need it just for Windows, but also for Linux it would be helpful I guess...
Also the download URLs of all needed files.

For example, SETI have this kind of thread in the forum.
And a 2nd thread for questions of the members.

Thanks.


[EDIT: Up to the time the admins do this maybe, I would be grateful if I could get help here in this thread before. ;-)]

34) Message boards : Number crunching : How to increase GPU Load at NVidia VGA card? (Message 63695)
Posted 10 Jun 2015 by Profile Sutaru Tsureku
Post:
I have a NV GT730.

I have let run:
MilkyWay@Home v1.02 (opencl_nvidia) [0.4% CPU time usage]
Milkyway@Home Separation (Modified Fit) v1.36 (opencl_nvidia_101) [2.7% CPU time usage]
... the GPU Load is just ~50% each on the GT730 with 1 app/WU.

How could I increase the GPU Load?
With the prefs?
Currently they are default:
- - - - - - - - - -
Maximum CPU % for graphics 0 ... 100 - 20

Frequency (in Hz) that should try to complete individual work chunks. Higher numbers may run slower but will provide a more responsive system. Lower may be faster but more laggy. - 60
default 60 (corresponds to 60 fps)
Period (in milliseconds) to check for scene updates - 30
Change how fast the view randomly moves around - 5
Make particles bigger or smaller - 250
Make particles bigger or smaller when using uglier particles - 40
- - - - - - - - - -
How (with which values) I should change it?


Or I should create an app_config.xml file for to let run 2 WUs/GPU?
How should look the entries?


Thanks.
35) Message boards : Number crunching : 4x HD7990 in one PC? (Message 61000)
Posted 7 Feb 2014 by Profile Sutaru Tsureku
Post:
I would like to build a new machine.

4x AMD Radeon HD7990 (dual GPU) graphic cards with ASUS Z9PE-D8 WS Motherboard and 2x Intel Xeon E5-2630v2 CPUs.

My question: Is this possible?

1 HD7990 use up to 375W fully loaded (in web test up to 395W).
2x 8pin PCIe power connector, 2x 150W= 300W
Over the PCIe slot 75W

How much wattage can go over the 24pin power connector?
I calculate with 50W for the motherboard/system-RAM,
and then 4x 75W/PCIe slot= 300W
(The both CPUs get power over 2x EPS power connector.)
So over the 24pin power connector must come at least 350W.
Can the 24pin power connector/cable of the power supply deliver at least 350W, or is this too much for the cable/plug or the plug at the motherboard?

I see now, the motherboard have also a 4pin molex plug.
Is this a connection to the motherboard or from the motherboard to other equipment? In which direction go the power?
How much wattage can go over this connection?

Thanks.

(BTW. Yes, this machine will do primary SETI, but during the weekly server maintenance there this machine will do Milkyway. ;-)

If I remember correct, MW@h results don't need wingmen for confirmation ..

But, all CPU results of my machine need 2 wingman for confirmation.

Is the stock CPU app buggy?

Are optimized CPU apps available which use the CPU instructions?
Or use the stock CPU app these already?

Thanks to all!

I did first the easiest way ;-) - I pressed a few times the update button - after a few times BOINC said:
Milkyway@home	13.02.2012 23:05:03	update requested by user	
Milkyway@home	13.02.2012 23:05:08	Fetching scheduler list

Milkyway@home	13.02.2012 23:05:14	Not reporting or requesting tasks	
Milkyway@Home	13.02.2012 23:05:17	Scheduler request completed


..later:
Milkyway@Home	13.02.2012 23:25:33	Sending scheduler request: To fetch work.	
Milkyway@Home	13.02.2012 23:25:33	Requesting new tasks for NVIDIA GPU	
Milkyway@Home	13.02.2012 23:25:36	Scheduler request completed: got 1 new tasks	
Milkyway@Home	13.02.2012 23:25:38	Started download of milkyway_separation_1.02_windows_intelx86__opencl_nvidia.exe



What are the best/fastest project settings for a nVIDIA GPU?
The GTX260 is only for crunching (secondary GPU) so lags are not a problem.. ;-)
Like this?
Maximum CPU% for graphics (0...100): 100
Frequency (in Hz) that should try to complete individual work chunks. Higher numbers may run slower but will provide a more responsive system. Lower may be faster but more laggy.
default 60.0 (corresponds to 60 fps):
1

My machine wanted again - after a longer break - MW@h WUs.

My machine: E7600 + GTX260, WinXP 32bit, nVIDIA driver 275.33, stock - no app_info.xml file, BOINC (V6.12.33) message:
Milkyway@home	13.02.2012 21:02:40	Sending scheduler request: To fetch work.

Milkyway@home	13.02.2012 21:02:43	Scheduler request failed: HTTP file not found


It's my machine or is there something wrong with the MW@h scheduler server?

Thanks.
