You had to quote his whole post to then break his app_info.xml file? Ofcourse the end </app> needs to be there. There was one <app> at the beginning of that section.

@OP, how did you write and save the app_info.xml file? Notepad, format ANSI?

Hi Tom, I would be interested in why your profile reports:

CPU type GenuineIntel
Intel(R) Xeon(R) CPU W3565 @ 3.20GHz [Family 6 Model 26 Stepping 5]
Number of processors 8
Coprocessors [2] NVIDIA Quadro FX 1800 (768MB) driver: 337.88 OpenCL: 1.0
Operating System Microsoft Wi ......

It was my understanding you had two different video cards.

Just saying.

There was some kind of invisible garbage in my app_info.xml file. When I replaced that file with a "fresh, clean, copy" Seti stopped reporting a syntax error and stopped deleting the bulk of the stuff in the directory.

Thanks,

I have a Nvidia Qudro 1800 and a Nvidia GeForce 8500 GT installed.

Once I was told how to get them setup so both are recognized using the cc_config.xml file. eg. the use all gpus parm set to 1. Putting that in the main Bonic directory and re-booting. Bonic promply got organized and started running 2 gpu tasks from Seti.

If someone had not pointed me to that I would still be going around mumbling "How do you get Bonic/Seti to recognize the 2nd gpu without attaching a monitor"...

:)

Thank you all!

As mentioned in another thread I did reach the point where I had 8 Seti tasks running on the 2 gpus while I was running 7 and sometimes 8 non-Seti tasks running on the cpus.

All it took was setting the numbers for Setiathome in the app_config.xml file that lives in the Seti data folder small enough. gpu was set at: 0.25 and cpu was set at 0.0175 or so. The idea was to have one or less cpu core handling all the gpu management.

Thanks,

my app_info.xml file.

The file referred to in this thread is the application configuration file, its name shortened to app_config.xml
With this file you can configure how many tasks BOINC should schedule to run on an appointed application and GPU. This file can be used with the default project provided science applications, and the third party science applications used through the anonymous platform module.

-- -- -- -- --

The application information file (app_info.xml) is used by anonymous platform applications, and is used so the user can dictate to BOINC what application it should run instead of the default science application provided by the project. This way you can use apps that are optimized specifically for your CPU/GPU, or that you compiled yourself.

-- -- -- -- --

The two aren't synonyms of each other. You can use an app_info.xml file at all times, with or without an additional app_config.xml file. Many of the things you can do in the app_config.xml file, you can do in the app_info.xml file. But for fine tuning the scheduling process, it's best to use the app_config.xml file.

Are you using a plain text editor like "notepad" or an xml-aware editor. Strange things can happen when using the latter, so ONLY use a plain text editor, and make sure the file is saved as <correct_file_name>.xml and not something like <correct_file_name>.txt.xml - that latter will not work!

"real" XML editors often put a unicode flag at the beginning of the file - this would appear to be invisible garbage.

I am not sure why it reported the Xeon having two "Nvidia Quadro's" At that time I was running the Quadro and an elderly GeForce.

Unfortunately the GeForce bit the dust. So I ordered a GTX 750 Ti after I discovered my current Xeon ps wasn't big enough to run a faster Radeon that I was lusting after. And yesterday a relative offered me a Radeon HD 5670 for a pretty modest price.

So it is installed and running. That proves that you can run two heterogeneous video technologies (CUDA and OpenCL) at the same time.

Then I had to give the Radeon back... darn it. It was crunching through stuff in a very respectable 20 minutes or so.

So I am waiting on the GTX 750 Ti to come to my relief. I have one machine (its pretty tiny though) that is taking about 8 hours to much thru a Radeon-based gpu task. And even my Quadro is frequently taking 2-3 hours. It has gotten better. Now Seti is mostly sending CUDA 22/23's and the munching is much quicker.

Thanks,

There is no such thing as a "CUDA23" task, all (well almost all) tasks can be processed by any of the MB apps, it is that they are dedicated to being processed by a particular app.
What is happening is that your GPU is being calibrated, you will get batches of tasks dedicated to each of the CUDA types, until the servers have worked out which type works best, which for your old Quadro will probably be either be 22/23 or 3x.
