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.
