Requirements
- ComputeCpp v0.3.2 or greater
- Python 2.7
- Ubuntu 16.04 LTS
- AMD R9 Nano / AMD FirePro GPU ( AMDGPU-PRO driver)
Intro
It’s a follow up from the previous post where set up on ubuntu 14.04 was described. The format is going to be the same “copy-paste” and “get-it-working” style.
Dependencies
The assumption is that you have a vanilla Ubuntu64 16.04.03 LTS installed.
Dependencies
Java & Bazel
1 2 3 4 5 | $ sudo apt-get install openjdk-8-jdk $ echo "deb [arch=amd64] http://storage.googleapis.com/bazel-apt stable jdk1.8" | sudo tee /etc/apt/sources.list.d/bazel.list $ curl https://bazel.build/bazel-release.pub.gpg | sudo apt-key add - $ sudo apt-get update && sudo apt-get install bazel $ sudo apt-get upgrade bazel |
OpenCL & SYCL
Note: In order to install only OpenCL parts of AMDGPU-PRO driver pass: –compute to ./amdgpu-pro-install
1 2 3 4 5 6 7 8 9 10 | $ sudo apt-get install ocl-icd-opencl-dev opencl-headers $ wget --referer=http://support.amd.comhttps://www2.ati.com/drivers/linux/ubuntu/amdgpu-pro-17.30-465504.tar.xz $ tar xvfJ amdgpu-pro-17.30-465504.tar.xz $ cd amdgpu-pro-17.30-465504 $ sudo ./amdgpu-pro-install #or sudo ./amdgpu-pro-install --compute $ wget http://computecpp.codeplay.com/downloads/computecpp-ce/latest/Ubuntu-16.04-64bit.tar.gz $ tar -xvzf Ubuntu-16.04-64bit.tar.gz $ sudo mkdir /usr/local/computecpp $ cd Ubuntu-16.04-64bit && cp * /usr/local/computecpp $ sudo reboot |
Python
1 2 3 4 | $ sudo apt-get install python-numpy python-dev python-wheel python-mock python-psutil $ sudo pip install --upgrade pip $ sudo pip install py-cpuinfo portpicker numpy $ sudo pip install --upgrade scipy |
Verification
1 | $ /opt/amdgpu-pro/bin/clinfo |
Should return something simillar to:

There is cl_khr_spir – good sign!
Now:
1 | $ /usr/local/computecpp/bin/computecpp_info |
For ComputeCpp CE 0.3.1 you should see:

Set Up
The changesets are being upstreamed however, for now I would recommend using my fork of the TensorFlow.
1 2 3 4 5 6 7 8 | $ export TF_NEED_OPENCL=1 $ export HOST_CXX_COMPILER=/usr/bin/g++ $ export HOST_C_COMPILER=/usr/bin/gcc $ export COMPUTECPP_TOOLKIT_PATH=/usr/local/computecpp $ git clone https://github.com/lukeiwanski/tensorflow.git $ cd tensorflow $ git checkout dev/eigen_mehdi $ ./configure |
At this point enter through the config questions.
In order to run tests:
1 | $ bazel test --test_timeout 300,450,1200,3600 -c opt --config=sycl --test_tag_filters=requires-gpu,-no_gpu,-no_oss,-oss_serial,-benchmark-test -- //tensorflow/... -//tensorflow/compiler/... -//tensorflow/contrib/distributions/... -//tensorflow/contrib/session_bundle/... -//tensorflow/go/... -//tensorflow/stream_executor/... -//tensorflow/core/distributed_runtime/... -//tensorflow/contrib/verbs/... -//tensorflow/contrib/xla_tf_graph/... -//tensorflow/java/... -//tensorflow/core/kernels/hexagon/... |
Worth to note at this point there are some fails that we are working on resolving.
Other “worth to mention” is the performance improvement that is still a “work-in-progress”.
1 2 | $ bazel build -c opt --config=sycl tensorflow/core/kernels:matmul_op_test $ ./bazel-bin/tensorflow/core/kernels/matmul_op_test --benchmarks=all |
On AMD Radeon FirePro W8100 gives:
Further optimisation improvements are in the pipeline.
