Results differences between emulation, and normal Emulation vs Normal, result differences

Accelerated Computing CUDA CUDA Programming and Performance

Hello,

I would like to get some advices from experienced CUDA programmers :)

Well, I parallelized the portion of the application, and it exactly produces the same outcome in the emulation mode. However, when I run the portion of the code on the GPU, then some result differences occur that lead to the undesired crash of the whole application…

I would like to get some advices on… what could be the potential Big areas that might lead to the different results ? is it synchronization ? is it the number of threads ? … and so on…

Thank you!

It is almost impossible to tell anything from such poor description of problem… You should at least clarify what you mean by “some result differences”.
