I am having problems with Cuda50 v8 units not running multiple units simultaneously on the new graphics card I have installed on my computer with SETI ID: 3324167 and SETI Name: Core2Duo:
--------------
GenuineIntel
Intel(R) Core(TM)2 CPU 6700 @ 2.66GHz [Family 6 Model 15 Stepping 6]
(2 processors)
--------------

My new card is:
--------------
NVIDIA GeForce GTX 750 Ti (2048MB) driver: 334.89 OpenCL: 1.1
--------------

I am still testing the capabilities of my new graphics card. At this time I am working with stock SETI. After completing my benchmarking I will upgrade to Lunatics, which is what I was using on my old card. I am currently attempting to run two units concurrently on my card. I set this up through app_config.xml, set as follows:
------------
<app_config>
<app_version>
<app_name>setiathome_v8</app_name>
<plan_class>cuda50</plan_class>
<avg_ncpus>0.20</avg_ncpus>
<ngpus>0.40</ngpus>
<app_name>setiathome_v8</app_name>
<plan_class>cuda42</plan_class>
<avg_ncpus>0.20</avg_ncpus>
<ngpus>0.40</ngpus>
</app_version>
<app_version>
<app_name>astropulse_v7</app_name>
<plan_class>opencl_nvidia_100</plan_class>
<avg_ncpus>0.20</avg_ncpus>
<ngpus>0.40</ngpus>
</app_version>
<project_max_concurrent>6</project_max_concurrent>
</app_config>
-------------

Initially the server sent me Cuda42 units. The Cuda42s had no problem running two at a time quickly and efficiently on my GTX750 Ti. Also, Astropulse V7 units run just as well two at a time (when I can get them - but that is another issue we all have). Then the server started sending me Cuda50 units instead of Cuda42s. The Cuda50s are listing on my BOINC task tab as (0.203 CPUs + 1 NVIDIA GPU).

I have been unable to override the "1 NVIDIA GPU" to run dual Cuda50 tasks on my card.

I would appreciate any help you can give me to resolve this issue, as my graphics card is running way below capacity, averaging only 54% average GPU load according to GPU-Z.

Thank you!

Your syntax is not correct, here's an app_config that actually works:

<app_config>
<app>
<name>astropulse_v7</name>
<gpu_versions>
<gpu_usage>0.5</gpu_usage>
<cpu_usage>0.7</cpu_usage>
</gpu_versions>
</app>
<app>
<name>setiathome_v7</name>
<gpu_versions>
<gpu_usage>.33</gpu_usage>
<cpu_usage>0.075</cpu_usage>
</gpu_versions>
</app>
<app>
<name>setiathome_v8</name>
<gpu_versions>
<gpu_usage>.33</gpu_usage>
<cpu_usage>0.075</cpu_usage>
</gpu_versions>
</app>
</app_config>

This one runs three MB or two AP on each GPU at a time.

You need to fix your app_config

I'll correct it for you
<app_config>
<app_version>
<app_name>setiathome_v8</app_name>
<plan_class>cuda50</plan_class>
<avg_ncpus>0.20</avg_ncpus>
<ngpus>0.40</ngpus>
</app_version>
<app_version>
<app_name>setiathome_v8</app_name>
<plan_class>cuda42</plan_class>
<avg_ncpus>0.20</avg_ncpus>
<ngpus>0.40</ngpus>
</app_version>

<app_name>astropulse_v7</app_name>
<plan_class>opencl_nvidia_100</plan_class>
<avg_ncpus>0.20</avg_ncpus>
<ngpus>0.40</ngpus>
</app_version>
<project_max_concurrent>6</project_max_concurrent>
</app_config>

My thanks to both of you!

I suspected it was a problem in my app_config file. I will try the fixes immediately and let you know how it goes.

By the way, is there anywhere I can find some documentation on configuring the app_config and the app_info files? It would certainly help me, but I haven't been able to locate some.

Thanks again!

There is wiki documentation for both files, showing what syntax is expected.

app_config.xml
app_info.xml

But you'll have to ask the users at each project you construct a file for, to help you with things like application names and (for app_info.xml) the names of any supporting files needed.

Thank you too, Richard!!
I will check them out!

Would any of these work on my Host #7258562? GTX660sc Kepler core.
I only want to run 2 V8 Cuda 42 0r 50 no astropulse on it as it Errors them out.
I'm running Stock on that Box.

Make sure you unclick Astropulses in your preferences on your account page so you don't get sent any APs


<app_config>
<app_version>
<app_name>setiathome_v8</app_name>
<plan_class>cuda50</plan_class>
<avg_ncpus>0.20</avg_ncpus>
<ngpus>0.40</ngpus>
</app_version>
<app_version>
<app_name>setiathome_v8</app_name>
<plan_class>cuda42</plan_class>
<avg_ncpus>0.20</avg_ncpus>
<ngpus>0.40</ngpus>
</app_version>
<project_max_concurrent>2</project_max_concurrent>
</app_config>

This should allow either any combo of cuda 42 or cuda 50 to run on your machine.

I'm assuming you know how to make a app_config.xml and where to place it?

If not, let us know.

Never done it always let the Optimized App do app_info.xml.
I think that it goes in the data folder for S@H...Will this also allow my 3 free cores to run V8

I Desire Peace and Justice, Jim Scott (Mod-Ret.)

If you want to run work on the CPU as well, you will need to change the number from 2 to 5 in the <project_max_concurrent>

To make a xml file, open notepad

Copy all that information into notepad and then click Save As

new window opens

Make sure at the very bottom encoding say ANSI

Save as type Change to all files (*.*)

Then in file name type in app_config.xml

It may ask you "do you really want to use that extension" yes you do

After you save it, move it to the Setiathome data folder.

You will then have to make BOINC Manager read the config files.

That should do it.

Let us know if you have any problems

Thanks Much Zalster. Will do in the AM EST.

Working like a charm so far! :)

Thank you rob smith! This app_config got my new GTX 980 running 3 cuda50's!

S@H keeps ignoring app_config.xml?

---

I Desire Peace and Justice, Jim Scott (Mod-Ret.)

Jim are you asking someone or saying yours is doing that?

Jim are you asking someone or saying yours is doing that?

Mine started doing it...Sporadically at first Now the log files say they find it , However S@H seems to ignore it.
It worked fine for weeks.

---

I Desire Peace and Justice, Jim Scott (Mod-Ret.)

I just make this suggestion to someone else, do you run CCleaner on your machine?

Try it on the registry and see if it resolves the issue. Don't know if it will help but can't hurt.

Jim are you asking someone or saying yours is doing that?

Mine started doing it...Sporadically at first Now the log files say they find it , However S@H seems to ignore it.
It worked fine for weeks.

I know BOINC will ignore the <cpu_usage>1.0</cpu_usage> setting if there are High Priority CPU tasks.
Maybe similar situations cause the whole thing to be ignored?

Don't have a clue. Ran CCleaner but no change.
