WebJul 24, 2009 · int atomicAdd (int * address, int val); This atomicAdd function can be called within a kernel. When a thread executes this operation, a memory address is read, has the value of ‘val’ added to it, and the result is written back to memory. The original value of the memory at location ‘address’ is returned to the thread.

Note that atomicAdd does not return the updated value, instead it returns the old value: cuda atomicAdd example fails to yield correct output. So all of your outputs are expected. In slist[0], even if you update the value with atomicAdd, you immediately overwrite it with the output of atomicAdd, the old value.This does not happen with the rest of the id, except they do indeed store 1 in slist ... Web[A,oldA] = gpucoder.atomicAdd(A,B) adds B to the value of A in global or shared memory and writes the result back into A.
