examples missing

[psychocoderHPC]

cupla has no examples of how atomic functions or other device functions should be used.

Please add more documentation.

@psychocoderHPC are you thinking of a simple demonstration, like the simpleAtomicIntrinsics sample in CUDA? Or smth more realistic?

[psychocoderHPC]

Yes a simple example like simpleAtomicIntrinsics would be nice. We should also have the usage of the memory hierarchy within those examples.
