I've been futzing for the past hour or so trying got get an app_info.xml file configured so that I can run two Milkyway WUs at a time in my NVIDIA GT 520 GPU (it runs single Milkyway WUs and multiple SETI WUs just fine).

Here's my most recent attempt for the Milkyway app_info.xml file:

<app_info>
<app>
<name>milkyway</name>
</app>
<file_info>
<name>milkyway_separation_1.02_windows_intelx86__opencl_nvidia.exe</name>
<executable/>
</file_info>
<app_version>
<app_name>milkyway</app_name>
<version_num>102</version_num>
<flops>4.0e10</flops>
<avg_ncpus>0.05</avg_ncpus>
<max_ncpus>1</max_ncpus>
<plan_class>cuda_fermi</plan_class>
<coproc>
<type>NVIDIA</type>
<count>0.5</count>
</coproc>
<cmdline></cmdline>
</app_version>
</app_info>

This is essentially the same as one I found in a search of the message boards that apparently worked. When I restart BOINC after installing the file, the file milkyway_separation_1.02_windows_intelx86__opencl_nvidia.exe gets deleted (it was definitely there before BOINC restarted!

Here's an excerpt from the log file:

HELP!!

Well, I found part of the problem: I left this out of the app_info file:

<file_ref>
<file_name>milkyway_separation_1.02_windows_intelx86__opencl_nvidia.exe</file_name>
<main_program/>
</file_ref>

At least the .exe file no longer gets deleted from the milkyway directory! However, I can't get it to download WUs!

Even with all other GPU projects suspended, I get this when I "update":

9/18/2012 8:52:36 PM | Milkyway@Home | Sending scheduler request: Requested by user.
9/18/2012 8:52:36 PM | Milkyway@Home | Not reporting or requesting tasks

Here's my current app_info file contents:

Now What??

Here's my current app_info file contents:

Now What??

I an app_info for nvidia cards that works for me:

<app_info>
<app>
<name>milkyway</name>
</app>
<file_info>
<name>milkyway_separation_1.02_windows_x86_64__opencl_nvidia.exe</name>

</app_version>
</app_info>

Remember that you NEED to use Boinc version 7.0.25 for Nvidia cards to work here, as anything higher from there up up thru 7.0.31 will NOT work! I see you are using 7.0.28, so downgrade and you should be fine. Now BEFORE you downgrade just know that ANY unit on your pc you have will be trashed as it is an older version, Boinc does well with upgrades but LOUSY with downgrades!! It is best to run thru your current units, after setting your projects to no new tasks, prior to downgrading. I would downgrade THEN check out the app_info again as you may not even need it unless you want to run multiple units at the same time.

That's strange -- my 7.0.28 works fine with SETI. If that is really the case, I'll just wait for 7.0.32 to be released and try again. Too much hassle to down-grade.

BTW -- your app_info fine looks about the same as mine, except your <class_plan> is cuda and mine is cuda_fermi.

SUCCESS!

I reset the milkyway project and restarted BOINC -- it downloaded WUs and has been happily crunching two WUs at a time in my GT 520 for the past couple of hours! And I am still running BOINC 7.0.28. Doing a scan of past posts regarding BOINC 7.0.25+, it appears that those experiencing errors were running higher end cards and/or a 64bit OS. I am running 32bit WinXP.

Just for the record, here is my app_info file that is working:

<app_info>

WOOHOO!!! I am VERY glad you got it working, I DO have a 560Ti AND Winy 64bit, so yes that could be the difference!

Oh and 7.0.36 is available for use, they are long past 7.0.32 already. Although I have NOT tried it on that pc yet.
