I am a newbie in programming Cuda, so this might not be the only question about it. I am running code on Cuda 6.0 but I have code with atomic function atomicAdd, are these functions supported by this version of toolkit ? Since it keeps showing me an error

Identifier "atomicAdd" is not defined

They are supported, but not for all datatypes! Can you show a [mcve] for what you are trying to do? – havogt Mar 11 '16 at 14:49

Also indicate what GPU you are running on and what is your compile command exactly. – Robert Crovella Mar 11 '16 at 15:30
here is the example i tried to run : https://github.com/udacity/cs344/blob/master/Lesson%20Code%20Snippets/Lesson%203%20Code%20Snippets/histo.cu – Emad Rawashdeh Mar 11 '16 at 16:19
@Emad, perhaps you've forgotten to `#include `? – einpoklum Mar 12 '16 at 11:31

@einpoklum you don't need to include that header file when compiling with `nvcc` – Robert Crovella Mar 12 '16 at 13:47
i compile it using the following command and it works : nvcc -arch=sm_35 -v – Emad Rawashdeh Mar 13 '16 at 21:13
