Small progress report ...
Fastest settings on my PC (J1900 + GT730), until now:
-v 0 -unroll 9 -ffa_block 896 -ffa_block_fetch 448 -tune 1 16 4 1 -use_sleep -cpu_lock -instances_per_device 2 -hp
[CUDA/0.5 in app_info.xml file]

I tested following:
-tune 1 8 4 1
-tune 1 16 2 1
-tune 1 16 4 1
-tune 1 32 2 1
-tune 1 32 4 1
-tune 1 64 2 1
-tune 1 64 4 1
... and like above mentioned '-tune 1 16 4 1' is fastest.
(other values are possible which I should test?)

I tested following:
-tune 2 8 1 1
-tune 2 16 1 1
-tune 2 32 1 1
-tune 2 64 1 1
-tune 2 128 1 1
-tune 2 256 1 1
... and no settings decreased the calculation times.
Like above mentioned no '-tune 2 N N N' in usage. What are the default settings which use the AP v7.10 (r2887) GPU app automatically?
(other values are possible which I should test?)

Thanks.

Not exactly, use "Start CMD /C ":
(but in fact a few seconds difference between starts don't matter so manual start is OK)

Put the file in:
C:\bla\bla\


@Echo OFF

CD bench01
Start CMD /C "APbench211.cmd"
CD ..

CD bench02
Start CMD /C "APbench211.cmd"
CD ..


Only for to be sure ...
You mean this in a .bat file (I added 'exit'(?))? (it looks like now it's named .cmd file, since Win7? - after searching the web)

- - - - - - - - - -
@Echo OFF
CD bench01

Thanks.

Maybe someone have a hint about what would be better (to reach max whole performance (RAC) of PC) on a J1900 CPU with GT730 GPU (?):
[assumed on CPU also AP tasks]

* AP GPU app, cmdline without -use_sleep
1 CPU-Core reserved for AP GPU calculation (<*_ncpus>1</*_ncpus> in app_info.xml file)
just 1 AP GPU app on GT730

vs.

* AP GPU app, cmdline with -use_sleep
2 AP GPU apps simultaneously on GT730

(It would be nice to know this, before I make the bench test runs ;-)

Thanks.

First I used (because in the AP stderr the Intel iGPU is named first, before the NV GPU):
AP7_xxxxxxxxxx.exe --device 1
... in BenchCfg.txt
But this didn't worked.

Then I used:
AP7_xxxxxxxxxx.exe --device 0
... in BenchCfg.txt
And it worked.

Then I used no '--device N'
... in BenchCfg.txt
And it worked also.

I chose the GT730 in GPU-Z and looked to 'GPU Load'. The 2nd and 3rd try the GT730 was loaded.
At the 1st try I didn't looked to the Intel iGPU, GT730 overview was also shown, but no matter the bench test run was stopped/finished immediately (it didn't worked). So I guess it tried on Intel iGPU.

I tested in both BenchCfg.txt files: -cpu_lock -instances_per_device 2
In Task-Manager 1 app at Core#0 and 1 app at Core#1.

OK, I made the following bench test run without '--device N'.
I made two folders, in each APbench/APbench211.cmd.
I tried a few .bat files, but I found not the correct entries (so that both bench test runs start to the same time).
So I started both with the mouse.

astropulse_7.10_windows_intelx86__opencl_nvidia_100.exe
As I tested 1st time this app live, following was used at default: -unroll 2 -ffa_block 512 -ffa_block_fetch 256

So I tested following (both apps simultaneously):

1st app:
-unroll 2 -ffa_block 512 -ffa_block_fetch 256 -use_sleep -cpu_lock -instances_per_device 2 -hp : Elapsed 578.466 secs CPU 15.547 secs
-unroll 3 -ffa_block 512 -ffa_block_fetch 256 -use_sleep -cpu_lock -instances_per_device 2 -hp : Elapsed 480.758 secs CPU 16.703 secs
-unroll 4 -ffa_block 512 -ffa_block_fetch 256 -use_sleep -cpu_lock -instances_per_device 2 -hp : Elapsed 471.458 secs CPU 14.141 secs
-unroll 5 -ffa_block 512 -ffa_block_fetch 256 -use_sleep -cpu_lock -instances_per_device 2 -hp : Elapsed 479.567 secs CPU 5.406 secs
-unroll 6 -ffa_block 512 -ffa_block_fetch 256 -use_sleep -cpu_lock -instances_per_device 2 -hp : Elapsed 479.016 secs CPU 5.188 secs

2nd app:
-unroll 2 -ffa_block 512 -ffa_block_fetch 256 -use_sleep -cpu_lock -instances_per_device 2 -hp : Elapsed 566.403 secs CPU 8.078 secs
-unroll 3 -ffa_block 512 -ffa_block_fetch 256 -use_sleep -cpu_lock -instances_per_device 2 -hp : Elapsed 480.212 secs CPU 3.719 secs
-unroll 4 -ffa_block 512 -ffa_block_fetch 256 -use_sleep -cpu_lock -instances_per_device 2 -hp : Elapsed 483.566 secs CPU 9.031 secs
-unroll 5 -ffa_block 512 -ffa_block_fetch 256 -use_sleep -cpu_lock -instances_per_device 2 -hp : Elapsed 480.005 secs CPU 4.531 secs
-unroll 6 -ffa_block 512 -ffa_block_fetch 256 -use_sleep -cpu_lock -instances_per_device 2 -hp : Elapsed 478.938 secs CPU 4.281 secs

I was curious and made a quick test if it work.

What should I test now?
Each settings a 2nd and 3rd run?

I should test higher values for -unroll?

What I should do now?

Thanks.

I overlooked the 'extended KWSN bench pack'? Because I couldn't find it.

Thanks.

This means 15:00 UTC to 23:00 UTC (8 hrs).

This would mean: 17. Sunday 17:00 to 18. Monday 01:00 (MiddleEuropeanSummerTime)

I myself wrote:
If I would add a NV GPU card to the J1900 PC ...

I set -cpu_lock for the Intel iGPU AP app.
I set -cpu_lock also for the NV GPU AP app.

Does this mean both apps are fixed at CPU-Core #0?
Or each GPU app get his own CPU-Core, #0 & #1?

Thanks.

Code for -cpu_lock is probably the same in all Raistmer apps.
So any app will see (at start) which cores are already in use by other running apps (if they also use -cpu_lock) and choose the first unused core (if unused core exists).

Yep, they should to do so.... but was never really checked with few different types of GPU installed. And it's quite easy to test.
Just open TaskManager when both app have running instances. Then look in affinity menu item what CPUs are checked for what process.

But even if both GPU apps happened to be pinned to the same core it can be still better than allow them to freely float between cores. Also, it's known that -cpu_lock has great impact on ATi app. Worth to directly check and show what its impact on iGPU's one.

-cpu_lock : Enables CPUlock feature. Results in CPUs number limitation for particular app instance. Also attempt to bind different instances to different CPU cores will be made.
Can be used to increase performance under some specific conditions. Can decrease performance in other cases though. Experimentation required.
Now this option allows GPU app to use only single logical CPU.
Different instances will use different CPUs as long as there is enough of CPU in the system.
To use CPUlock in round-robin mode GPUlock feature will be enabled. Use -instances_per_device N option if few instances per GPU device are needed.


So, maybe -instances_per_device 2 will be needed in this case too. Check that.

@Dirk
To clarify: this doesn't mean you have to run 2 instances on one GPU

You may even use -instances_per_device 4 (just to 'reserve' counter for max 4 apps running)
- since BOINC starts the apps it will still start only 2 apps (one per GPU) unless you change this by app_info.xml / app_config.xml

- - - - - - - - - -

OK, in ap_cmdline_win_x86_SSE2_OpenCL_Intel.txt: -cpu_lock -instances_per_device 1
in ap_cmdline_win_x86_SSE2_OpenCL_NV.txt: -cpu_lock -instances_per_device 2 (I let run 2 tasks simultaneously on GT730 (app_info.xml CUDA/0.5))

The result in Task-Manager:
1 Intel iGPU app at Core#0
1 NV GPU app at Core#0 and 1 NV GPU app at Core#1

What I need to change, that 1 NV GPU app (1st) use Core#1 and 1 NV GPU app (2nd) use Core#2?
(And Intel iGPU app use still Core#0)

Thanks.


BTW. With the above mentioned settings, the Intel iGPU app/task calculation increased from 17hrs to 18.5hrs (since I added the GT730 VGA card).

On Sunday, May 17th campus is upgrading the network infrastructure at the facility hosting our servers. We will bringing the projects down for about 6-8 hours (starting at 8am, Pacific Time) to avoid complications during the upgrade.


http://setiathome.berkeley.edu/utc.php

8am PT, is -8 hrs UTC.

This means 16:00 UTC to 24:00 UTC (8 hrs) - right?

This would mean: 17. Sunday 18:00 to 18. Monday 02:00 (MiddleEuropeanSummerTime)

Example:
I have one APbench211.cmd in:

C:\bla\bla\bench01\APbench211.cmd
and in:
C:\bla\bla\bench02\APbench211.cmd

If I would like to execute both simultaneously,
I could make a .bat file?
How should look it?

Just like this in a .bat file (?) :
"C:\bla\bla\bench01\APbench211.cmd"
"C:\bla\bla\bench02\APbench211.cmd"

... and both bench test runs start simultaneously?

Thanks.

It looks like since ~7 hours the overviews are not up to date.

I sent E-Mail to the admins (David, Eric, Matt, Jeff).

In Germany we have today a free day ("Christi Himmelfahrt") 'Ascension of Christ'(?) and 'Father's Day'.
In the USA today it's also a free day?

Application details for your host 7564005: http://setiathome.berkeley.edu/host_app_versions.php?hostid=7564005

The 2nd line 'Max tasks per day' at every app.

If you, aborting tasks or detach/attach at the project (and 're-sent tasks feature' is switched off by the admins) you get errors.
1 error and you are down to just 33 tasks/day.
If you have a bunch or errors, you are down to 1 task/day.
Your PC need to calculate tasks and upload & report results, for to increase this value again.

Thanks again.

Which tool & test task I must use for to let run SETI (MB) bench test run (simultaneously) on NV (GT730) GPU?

lunatics.kwsn.info/ Test Tools - MultiBeam -

Thanks.

BTW, I ask all first, before I make all bench test runs (I didn't have done this before, it's new for me (SETI (MB) runs - and 2 tasks simultaneously)).
I could waste my time. ;-)
My PC don't crunch AP/SETI tasks during the bench test runs ... - not good for the SETI project. ;-)

AFAIK, this is a database 'error'.

http://setiathome.berkeley.edu/sah_status.html
Master database queries/second 1,558 0m
Replica seconds behind master Offline 0m

AFAIK,
the 'real' data are saved on the master database,
the overviews we see are from the replica.

They are not 'sync' currently.

I sent already an E-Mail to the admins.

BTW, Credits will be granted for already uploaded and reported results.
