CUDA - invalid device function

[Franz]

Please, look at this task:

http://setiathome.berkeley.edu/result.php?resultid=1339584737

Code: [Select]

setiathome_CUDA: Found 1 CUDA device(s):

Computer is GenuineIntel
Intel(R) Core(TM)2 Quad CPU Q6700 @ 2.66GHz [x86 Family 6 Model 15 Stepping 11]
(4 processors) with   NVIDIA GeForce 8500 GT (511MB) driver: 19038
Optimized application by Win32 Lunatics' Unified Installer v0.2 (working well with other geforce CUDA).

As I can see, even if totalGlobalMem = 536543232 and I use new drivers 19038,
at running time
Total GPU memory 0  free GPU memory 0
and so the task given back to the CPU.

I forgot to tell that I use also Cuda2.3rt_fft_dlls.7z  downloaded from here.

I ask why, if you know, GPU memory can be zero.

Bye,

More info

I have made a full reinstall of Win32 Lunatics' Unified Installer v0.2
and Cuda2.3rt_fft_dlls.7z

As BOINC 6.6.36 stats I read:

Do you know the meaning of the errors?

Now I see 5 task running (4 CPU and 1 GPU) but I have to wait the end of the GPU's to look in the task result.

All OK now
Problem closed

[cryptokid]

problem solved for me too.

thanks guys.
