In last weeks I observed that CUDA can freeze your system and you aren’t able to do anything.
I asked around an I’m not the only one who had such a expierence.
Probably there is something wrong with my kernel, but this behavior is annoying, because you
have to reboot.
I hoped system freezes (caused by user level programs) are a problem of the past and that
we had overcome this problem with the introduction of virtual adress spaces.
How memory is handled on the GPU? Is there any memory protection or can my CUDA
kernel overwrite the complete memory? My kernel can at least freeze my machine and
I didn’t like this at all.
My machine is Win XP x64 with 6 GB RAM and the GPU is Quadro FX 4800.
I’m using CUDA 2.3 and compile it to 32 Bit.
