1) Message boards : Number crunching : SETI & MW on one NV GPU simultaneously? (Message 1696546)
Posted 2 days ago by Profile Dirk SadowskiProject donor
Thanks.

So I understand it correct?
1 SETI and 1 Milkyway WU should run simultaneously on my NV VGA card?

Next time I'll try the <work_fetch_debug>.

How should look an app_config.xml file for Intel iGPU (1 WU for SETI or AP) and NV GPU (2 WUs for SETI or 1 WU for AP), like this?

<app_config> <app> <name>setiathome_v7</name> <gpu_versions> <gpu_usage>1.0</gpu_usage> <cpu_usage>0.04</cpu_usage> </gpu_versions> </app> <app_version> <app_name>setiathome_v7</app_name> <plan_class>opencl_intel_gpu_sah</plan_class> <avg_ncpus>0.04</avg_ncpus> <ngpus>1.0</ngpus> <cmdline></cmdline> </app_version> <app> <name>setiathome_v7</name> <gpu_versions> <gpu_usage>0.5</gpu_usage> <cpu_usage>0.04</cpu_usage> </gpu_versions> </app> <app_version> <app_name>setiathome_v7</app_name> <plan_class>cuda50</plan_class> <avg_ncpus>0.04</avg_ncpus> <ngpus>0.5</ngpus> <cmdline></cmdline> </app_version> <app> <name>astropulse_v7</name> <gpu_versions> <gpu_usage>1.0</gpu_usage> <cpu_usage>0.04</cpu_usage> </gpu_versions> </app> <app_version> <app_name>astropulse_v7</app_name> <plan_class>opencl_intel_gpu_102</plan_class> <avg_ncpus>0.04</avg_ncpus> <ngpus>1.0</ngpus> <cmdline></cmdline> </app_version> <app> <name>astropulse_v7</name> <gpu_versions> <gpu_usage>1.0</gpu_usage> <cpu_usage>0.04</cpu_usage> </gpu_versions> </app> <app_version> <app_name>astropulse_v7</app_name> <plan_class>opencl_nvidia_100</plan_class> <avg_ncpus>0.04</avg_ncpus> <ngpus>1.0</ngpus> <cmdline></cmdline> </app_version> </app_config>

Or the Intel iGPU and NV GPU don't need entries, if just 1 WU?

Then just an app_config.xml file with entries for SETI NV GPU?
<app_config> <app> <name>setiathome_v7</name> <gpu_versions> <gpu_usage>0.5</gpu_usage> <cpu_usage>0.04</cpu_usage> </gpu_versions> </app> <app_version> <app_name>setiathome_v7</app_name> <plan_class>cuda50</plan_class> <avg_ncpus>0.04</avg_ncpus> <ngpus>0.5</ngpus> <cmdline></cmdline> </app_version> </app_config>



(in both cases the app_info.xml file entries not changed, still with all...?
... <avg_ncpus>****</avg_ncpus> <max_ncpus>****</max_ncpus> <plan_class>****</plan_class> <coproc> <type>****</type> <count>****</count> </coproc> ...

Or I need to delete this entries in one or both of this two mentioned app_config.xml file versions?

Thanks.

I let run 2 SETI (MB) WUs simultaneously on my NV GT730.

In the setiathome.berkeley.edu project folder is an app_info.xml file with CUDA/0.5.

In the milkyway.cs.rpi.edu_milkyway project folder is an app_config.xml file with:
<app_config> <app> <name>milkyway</name> <gpu_versions> <gpu_usage>0.5</gpu_usage> <cpu_usage>0.1</cpu_usage> </gpu_versions> </app> <app> <name>milkyway_separation__modified_fit</name> <gpu_versions> <gpu_usage>0.5</gpu_usage> <cpu_usage>0.1</cpu_usage> </gpu_versions> </app> </app_config>


If I suspend all SETI CUDA WUs, just let run one SETI CUDA WU, BOINC don't ask at Milkyway (project share 0) for a new WU.

If BOINC have no SETI CUDA WUs, BOINC ask at Milkyway for new WUs.

If SETI have no new CUDA WUs ready for download, it's just one SETI CUDA WU in BOINC, it's possible that SETI and Milkyway run simultaneously on my NV GT730?

Thanks.

PS. If I add a 'setiathome_v7 <app>' entry to the Milkyway app_config.xml file BOINC say 'unknown app'.
I need to make an app_config.xml file also for SETI?

4) Message boards : Number crunching : NV GPU - AP bench test run (e.g. @ GT730) (Message 1696205)
Posted 4 days ago by Profile Dirk SadowskiProject donor
Because of the last messages/questions...

I made a quick test with Fred's SetiPerformance (I added manually the cuda42 app) (count 1.0):
x41zc_cuda50: 755 Seconds (12 Minutes, 35 Seconds)
x41zc_cuda42: 784 Seconds (13 Minutes, 4 Seconds)

So it looks like the cuda50 app is faster (at least on my system).

In GPU-Z it shows GPU Load just ~80% with count 1.0.
So I let run count 0.5 (2 SETI (MB) project tasks simultaneously) on my NV GT730 (PCIe 2.0 x1 plug & slot).
(After a quick test with Fred's SetiPerformance it looks like 2 SETI (MB) project tasks simultaneously on my GT730 give highest overall (CPU & NV GPU) RAC (on my system).
3 SETI (MB) project tasks simultaneously are also possible, but just +1% RAC for the NV GPU. In the same time -1.9% CPU RAC, because more CPU time usage of the 3rd GPU app.
)

@ KLiK
I see you let run just the stock GPU apps.
If you don't want to install the opti apps of the Lunatics crew you should let run at least also 2 SETI WUs/NV GT730.
If I edit my Milkyway app_config.xml file (which work there very well) the SETI app_config.xml file entries could/should work with:
<app_config> <app> <name>setiathome_v7</name> <gpu_versions> <gpu_usage>0.5</gpu_usage> <cpu_usage>0.1</cpu_usage> </gpu_versions> </app> <app> <name>astropulse_v7</name> <gpu_versions> <gpu_usage>1.0</gpu_usage> <cpu_usage>0.006</cpu_usage> </gpu_versions> </app> </app_config>

(cpu_usage from my PC, maybe you take 0.04 like in Lunatics' app_info.xml files)

This means:
2 SETI WUs/GPU
1 AP WU/GPU

(Because of CreditNew I let run 2 SETI and 1 AP WUs/GPU, because if 1 SETI and 1 AP WU simultaneously, the AP WU is ~50% faster. This would screw up the 'average processing rate x.x GFLOPS'.

I made bench test runs on my NV GT730 and the fastest settings are:
2 AP WUs/GPU: -v 0 -unroll 9 -ffa_block 896 -ffa_block_fetch 448 -tune 1 16 4 1 -oclFFT_plan 256 32 64 -use_sleep -cpu_lock -instances_per_device 2 -hp
1 AP WU/GPU: -v 0 -unroll 11 -ffa_block 1792 -ffa_block_fetch 448 -tune 1 16 4 1 -tune 2 16 1 1 -oclFFT_plan 256 16 256 -use_sleep -cpu_lock -instances_per_device 1 -hp

I have opti apps installed (app_info.xml file usage), so this cmdline entries are in the ap_cmdline_win_x86_SSE2_OpenCL_NV.txt file at my PC.
I guess if stock you should find this file also in the setiathome.berkeley.edu project folder. Open it with Notebad and insert the entries and save.

In the setiathome.berkeley.edu project folder is also a mbcuda.cfg file.
Open it with Notepad and delete the ; at the beginning in the line of:
processpriority = abovenormal
...and save.
Then the SETI CUDA app get better CPU support (maybe faser calculation on GPU).

I can't install the NV GPU driver with help of the NV driver .exe.
If I execute this install tool, it don't find the GT730 (it say: 'no NVidia VGA card found').
I have the screen connected to the Intel iGPU output.
The GT730 is the secondary VGA card and nothing connected, also no VGA dummy plug.
I guess this is the problem that the NV driver .exe don't find a NV VGA card.
I guess Windows 8.1 installed a 'Windows certified' driver (347.52) or something.
I have no idea where this driver came from.
I have not downloaded it, and Windows had just ~10 seconds to search and download (100+MB not possible with my DSL2000 in this short time).
So I have no idea which kind of driver this is (Windows/Software no MB size shown) which is installed now (maybe a 'shortened' driver?).
So I can install a new NV driver just if Windows say 'a new driver available' (I don't know if this could happen, if Windows have this function) or I go to the device-manager and let search a new driver there over properties.

11) Message boards : Number crunching : NV GPU - AP bench test run (e.g. @ GT730) (Message 1687538)
Posted 27 days ago by Profile Dirk SadowskiProject donor
I unfortunately don't understand ...

I start to find fastest settings, with:
1. -unroll N
2. -ffa_block N & -ffa_block_fetch N
3. -tune 1 N N N
4. -tune 2 N N N
5. -oclFFT_plan N N N

After which test I should continue with 2 separate test runs (1 with -use_sleep 1 without -use_sleep)?
After the 2., at point 3 continue with 2 separate test runs?

With other words ...
1st I test 1. up to 5. without -use_sleep.
Where I should start the 2nd run with usage of -use_sleep? At point 3?

Thanks.

Posted 28 days ago by Profile Dirk SadowskiProject donor
OK, on my Intel Celeron CPU J1900 with NVIDIA GeForce GT 730 (with PCIe 2.0 x1 plug & speed):

app: astropulse_7.10_windows_intelx86__opencl_nvidia_100.exe (r2887)

The start with the default settings (bench test run with 2 AP WUs/GPU):
-v 0 -unroll 2 -ffa_block 512 -ffa_block_fetch 256 -use_sleep -cpu_lock -instances_per_device 2 -hp
Elapsed 565.38 secs CPU 11.97 secs

The finally fastest settings (bench test run with 2 AP WUs/GPU):
-v 0 -unroll 9 -ffa_block 896 -ffa_block_fetch 448 -use_sleep -cpu_lock -instances_per_device 2 -hp -tune 1 16 4 1 -oclFFT_plan 256 32 64
Elapsed 383.53 secs CPU 8.37 secs

'Live' this means 2 AP WUs/GPU in 7.5 hrs (default) down to 6 hrs (fastest settings).

- - - - - - - - - -
If I would like to know the fastest settings for 1 AP WU/GPU (with and without -use_sleep) ...

I start the bench test run (without -use_sleep) with -unrull, -ffa_* ... and so on ...
Then I found the fastest settings for without -use_sleep.

At the end I test the fastest found settings then with -use_sleep, I found also the fastest settings with -use_sleep?

Or I need to start again from scratch with -use_sleep from the beginning and need to test all possible settings & values again?
- - - - - - - - - -
Finally ...
For to find the fastest settings for 1 AP WU/GPU (with and without -use_sleep), I need just 1 (at the end -use_sleep test) or 2 (1 without 1 with -use_sleep from beginning) whole bench test runs?

Thanks.
13) Message boards : Number crunching : Just deleting the flops in app_info.xml file and fine? (Message 1686758)
Posted 29 days ago by Profile Dirk SadowskiProject donor
I have an app_info.xml file with flops entries.

This values are the same which are displayed at 'average processing rate' on the 'application details' overview.

E.g. above mentioned overview: 9.86 GFLOPS
flops entry in app_info.xml file: 9.86e09

I can just delete all flops entries in the app_info.xml file and it's fine?

Or the estimated times for the already downloaded WUs in BOINC will go 'crazy' (increase or decrease?)? Finally the WUs will end with ('-177') errors?

Thanks.

Long story short.. I don't particularly think this is specifically an issue with not letting two overflow results go without a CPU's opinion (because all that will end up happening is the CPU's result won't match the majority, and the CPU's result will be discarded as invalid--which is what already happens quite frequently anyway).
(...)

I would suggest (if it's server 'technically' possible),
each '-9 overflow' result which comes from a VGA card, this WU should be send additional to a CPU (- only host, or to the CPU of a host) for to check if it's really a '-9 overflow'.

If 2 VGA cards send respectively a '-9 overflow' result, two CPUs check if they are correct.
So at this WU: 2 VGA cards with '-9 overflow' and 2 CPUs with well results.

This way the science is rescued.

If you click to this kind of 'bad' hosts, and then to the overview 'valid' tasks of this hosts, look to them and then you will see wrong '-9 overflows' results which are marked as valid, and wingman with 'well' result but marked as invalid (at this WUs).

Examples:

And always the '-9 overflow' is in the data base, and the well results are destroyed.

Maybe it would be better if a VGA card send a '-9 overflow' result back, it should be calculated on a CPU again if there is really a '-9 overflow'.
If it's true, it lasts just a few seconds.
If it's not true, the science is rescued.

Just two wingman of one task ...
