I wrote a program using cuda function from an existing code.
Unfortunately the data result using cuda is wrong. Now I have to understand why.
There are no cuda error.
It could be a programming error, but the strange thing is that, if I try to compile the cuda code with flag “-deviceemu”, the result is correct.
Now, I’d like to know if this difference of result due to emulation flag can be possibile or not.
The os is ubuntu 9.10 64 bit with nvidia driver 190.53 and cuda toolkit 2.3.
