Status

03/11/2020: successfully built cython-0.29.21-foss-2019b-Python-3.7.4, numpy-1.18.1-foss-2019b-Python-3.7.4, SciPy-bundle-2020.03-foss-2019b-Python-3.7.4, Bazel-0.26.1-foss-2019b, h5py-2.10.0-foss-2019b-Python-3.7.4.

04/11/2020: TensorFlow 1.15.2 successfully built and installed, using CUDA 10.1.243

19/11/2020: gomkl toolchain built with Intel MKL 2019.1.144

21/11/2020: successfully built everything (including TensorFlow 1.15.2) with the gomkl toolchain.

To use:

module use -a /cluster/shared/nlpl/software/easybuild_ak/easybuild/install/modules/all/

module load NLPL-TensorFlow/1.15.2-gomkl-2019b-Python-3.7.4

Remaining issues

• In order to keep the modules NLPL-branded, environment variables must be added manually to the module files. Without that, modules load fine, but cannot be used as dependencies in building other modules.
• TensorFlow is built with CUDA 10.1.243, not CUDA 10.0.130. Attempts to use the latter failed. Should find a way to make EasyBuild look for a non-standard CUDA location.
• Check whether using gompi instead of gompic (with CUDA) leads to problems with multi-node training. Multi-GPU training on a single node is confirmed to work.
