Important stuff to remember

export EB_PYTHON=python3

module load EasyBuild/4.3.0

Playground on Saga: /cluster/shared/nlpl/software/easybuild_ak

Real module location: /cluster/projects/nn9851k/software/easybuild/install/modules/all/

export EASYBUILD_ROBOT_PATHS=/cluster/software/EasyBuild/4.3.0/easybuild/easyconfigs:/cluster/projects/nn9851k/software/

(or just source PATH.local)

Repository: https://source.coderefinery.org/nlpl/easybuild/-/tree/ak-dev

To use:

module use -a /cluster/projects/nn9851k/software/easybuild/install/modules/all/

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

Remaining issues

  • 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.

Deployment on Puhti

Location: /projappl/nlpl/software/andreku

Initial setup:

  • Install EasyBuild (we need its easyconfigs in robot-paths)
  • module use -a /projappl/nlpl/software/andreku/modules/all
  • module load EasyBuild
  • source SETUP.local

We are building everything from scratch. We borrow the necessary binary blobs from Saga, they are stored on Puhti in /projappl/nlpl/software/andreku/extdownloads. In fact, only three such tarballs are needed to eventually build the NVIDIA BERT implementation:

  1. jdk-8u212-linux-x64.tar.gz to build Java to build Bazel to build TensorFlow,
  2. cudnn-10.1-linux-x64-v7.6.4.38.tgz to build cuDNN to build TensorFlow,
  3. nccl_2.6.4-1+cuda10.1_x86_64.txz to build NCCL to build TensorFlow.

All the required easyconfigs, scripts, etc can be found in the `scratch` branch.

There was an issue with GCC building, fixed by manual intervention in the MPC tarball. A more general solution (applicable not only to GCC but also to Java, and other packages as well) is to change the EasyBuild build directory to any location not on Lustre distributed file system. One can simply use $TMPDIR (this is a local ext4 partition).

Bazel, TensorFlow and PyTorch must be built on a compute node; it seems that the Puhti login nodes are too restrictive in terms of maximum thread number. In this case, the build directory should be set to $LOCAL_SCRATCH:
