After a lot of struggles:
Built successfully Tensorflow with OpenCL on fresh Ubuntu 16.04 with amdgpu 17.50.
Have 5 identical GPUs (rx580) installed and all of them are reported by clinfo and computecpp_info as expected.
Running the MNIST convnet example, TF works but emplyes just GPU0 without seeing other GPUs.
There are no errors reported in dmesg about the card, they seem all to be ready at the lowest layer, don't know why SYCL seems to be ignoring some cards.
Here is computecpp_info output:

EDIT: It is not related to any specific card, just the first available in bus order.
I tried disconnecting some cards and after all the tests it seems clear that SYCL always lists just the first GPU, no matter which one, always the minimum available bus number.
This also confirms that there are no differences among the cards and that all of them can be used (at least individually), so the OS I think is fine and i would guess the problem is in SYCL.
Please help!
