После многих трудностей:
Успешно построен Tensorflow с OpenCL на свежем Ubuntu 16.04 с amdgpu 17.50 .
Установлено 5 идентичных графических процессоров (rx580) , и все они сообщаются clinfo и computecpp_info, как и ожидалось.
При выполнении примера с вызовом MNIST TF работает, но использует только GPU0, не видя других графических процессоров .
* об ошибках не сообщается *1028* вdmesg о карте, кажется, что все они готовы на самом низком уровне, не знаю, почему SYCL, кажется, игнорирует некоторые карты .
Вот computecpp_info вывод:

РЕДАКТИРОВАТЬ: Это не связано с какой-либо конкретной карты, только первая доступна в порядке шины.
Я попытался отключить некоторые карты, и после всех испытаний кажется, что SYCL всегда перечисляеттолько первый GPU, независимо от того, какой именно, всегда минимальный доступный номер шины.
Это также подтверждает, что между картами нет различий и что все они могут быть использованы (по крайней мере, по отдельности), поэтому ОС, я думаю, в порядке, и я предполагаю, что проблема в SYCL.
Пожалуйста, помогите!
