I have some experience using app_info.xml, I was messing with it on milkyway@home and primegrid when I heard about the possibility of multiple applications running on gpu.

Could you create this version with sm_10 only flag, please?

I'd like to know if it's my gpu that has a problem, as I tested primegrid with cuda 5 and I got the same exception.
Maybe this issue is associated with driver or libcuda giving wrong values for some parameters, like this:

(only differences)

Windows client_state.xml:

<coproc_cuda>
<available_ram>4149374976.000000</available_ram>
<drvVersion>31422</drvVersion>
<maxGridSize>65535 65535 65535</maxGridSize>
<coproc_opencl>
<max_clock_frequency>758</max_clock_frequency>
<max_compute_units>7</max_compute_units>
</coproc_opencl>
</coproc_cuda>


Linux client_state.xml:

<coproc_cuda>
<available_ram>4037357568.000000</available_ram>
<drvVersion>0</drvVersion>
<maxGridSize>2147483647 65535 65535</maxGridSize>
<coproc_opencl>
<max_clock_frequency>7018911954001462006</max_clock_frequency>
<max_compute_units>7164775588903780359</max_compute_units>
</coproc_opencl>
</coproc_cuda>


But that's just my conjecturing. ;)

Hi,

I'm having issues using collatz 4.04 cuda.
Every wu that I ran aborted with a floating point exception.
This is one of my failed tasks.

I put a strace here http://pastebin.com/1sJmqzdk (if that helps).

I'm using debian unstable now, but I have tested on debian 7 stable, linux mint 14, ubuntu 13, using the latest cuda-toolkit, and I saw the same exception occuring always.

Another point is that I can run the same app on windows without problems, and I'm testing einstein@home without any problems, at least for now.

Someone experienced this?
