Hello everyone,
I am trying to compute an addition on the same global memory with the help of the atomic function: atomic_add()
I have seen that I have to add “#pragma OPENCL EXTENSION cl_khr_global_int32_base_atomics:enable” to my “.cl”
Unfortunately, Visual studio is not very happy with this :doh: and told me:
<kernel>:528:6: error: no matching function for call to 'atom_add'
atomic_add(F[i], absorb);
^~~~~~~~~~

I really do not understand what’s wrong with my code…
My GPU is a NVidia k620.
Can someone help me, please? Thank you in advance
