How to Rebuild Tensorflow With the Compiler Flags?

4 minutes read

To rebuild TensorFlow with specific compiler flags, you can follow these steps:

  1. Identify the desired compiler flags that you want to use for the rebuild process.
  2. Clone the TensorFlow repository from GitHub or download the source code.
  3. In the TensorFlow source code directory, locate the configure file, which is usually named configure or configure.py.
  4. Modify the configure file to include your desired compiler flags. This may involve editing the build configuration options or creating a custom build script.
  5. Run the configure script with the appropriate flags to generate the build configuration based on your changes. This will create the necessary build files for compilation.
  6. Compile TensorFlow by running the build command, which is typically bazel build in TensorFlow's case. Make sure to include any additional flags or options required for the compilation process.
  7. Once the compilation is complete, test the rebuilt TensorFlow with the new compiler flags to ensure that it is functioning correctly.
  8. You can now use the rebuilt TensorFlow with the specified compiler flags for your projects or applications.


How to rebuild TensorFlow with NUMA optimizations using compiler flags?

To rebuild TensorFlow with NUMA optimizations using compiler flags, follow these steps:

  1. Clone the TensorFlow repository from GitHub:
1
git clone https://github.com/tensorflow/tensorflow.git


  1. Navigate to the TensorFlow directory:
1
cd tensorflow


  1. Configure TensorFlow build using the following command:
1
./configure


During configuration, make sure to select the appropriate compiler and compiler flags for your system.

  1. Edit the TensorFlow build script to include NUMA optimizations:
1
vim tensorflow/tensorflow/core/platform/default/build_config/BUILD


Add the following NUMA compiler flags to the tf_custom_opt_flags, tf_ops_xla_gpu_features and tf_named_ops_xla_gpu_features sections:

1
2
        "-Wl,--numa-interleave",
        "-Wl,--membind=<NUMA Node ID>"


Replace <NUMA Node ID> with the NUMA node ID on which you want to bind the process memory.

  1. Save the changes and close the file.
  2. Rebuild TensorFlow using Bazel build system with the following command:
1
bazel build --config=opt //tensorflow/tools/pip_package:build_pip_package


  1. Once the build process is complete, you can install the newly built TensorFlow package using:
1
2
bazel-bin/tensorflow/tools/pip_package/build_pip_package /tmp/tensorflow_pkg
pip install /tmp/tensorflow_pkg/<tensorflow_package_name>.whl


After following these steps, you should have successfully rebuilt TensorFlow with NUMA optimizations using compiler flags.


How to rebuild TensorFlow with the compiler flags for improved performance?

To rebuild TensorFlow with specific compiler flags for improved performance, follow these steps:

  1. Clone the TensorFlow repository from GitHub:
1
git clone https://github.com/tensorflow/tensorflow.git


  1. Install Bazel build system (if you don't have it already):
1
sudo apt-get update && sudo apt-get install bazel


  1. Navigate to the TensorFlow directory:
1
cd tensorflow


  1. Configure TensorFlow for building with specific compiler flags. You can modify the ./configure script to specify the compiler flags you want. For example, to use specific optimization flags, you can edit the script to include the following flags:
1
2
3
4
5
6
7
8
9
export TF_ENABLE_XLA=1
export TF_NEED_OPENCL_SYCL=0
export CC_OPT_FLAGS="-march=native"
export TF_NEED_CUDA="0"
export TF_NEED_ROCM="0"
export GCC_HOST_COMPILER_PATH="/usr/bin/gcc"
export TF_CUDA_COMPUTE_CAPABILITIES="3.5,5.2,6.1,7.0"
export TF_NEED_AWS=0
export TF_NEED_GCP=0


  1. Run the configuration script:
1
./configure


  1. Build TensorFlow with the specified compiler flags:
1
bazel build --config=opt //tensorflow/tools/pip_package:build_pip_package


  1. After the build is complete, you can package TensorFlow into a wheel file for installation:
1
./bazel-bin/tensorflow/tools/pip_package/build_pip_package /tmp/tensorflow_pkg


  1. Install the newly built TensorFlow package:
1
pip install /tmp/tensorflow_pkg/tensorflow-<version>-cp37-cp37m-linux_x86_64.whl


By following these steps, you can rebuild TensorFlow with specific compiler flags to optimize its performance for your system.


How to specify compiler flags for optimizing TensorFlow on ARM processors?

To specify compiler flags for optimizing TensorFlow on ARM processors, follow these steps:

  1. Open the TensorFlow source code in your preferred code editor.
  2. Locate the build configuration files, such as "configure" or "CMakeLists.txt", where compiler flags are set.
  3. Add or modify the compiler flags to include optimization options specifically for ARM processors. Some common optimization flags for ARM processors include:
  • -march=: Specifies the target ARM architecture. For example, for ARM Cortex-A53 processors, you can use -march=armv8-a.
  • -mfpu=: Specifies the floating-point unit (FPU) to use. For example, for ARM Cortex-A53 processors, you can use -mfpu=neon-fp-armv8.
  • -mfloat-abi=: Specifies the float ABI to use. For ARM Cortex-A53 processors, you can use -mfloat-abi=hard.
  1. Save the changes to the build configuration files.
  2. Rebuild TensorFlow using the updated compiler flags by running the build commands for your platform. This may involve running scripts such as ./configure or cmake followed by make.


By specifying compiler flags optimized for ARM processors, you can improve the performance of TensorFlow on these devices. Remember to test the optimized build to ensure it works correctly and achieves the desired performance improvements.
