Tensorflow on Slurm
This package makes it easier to run distributed TensorFlow jobs on slurm clusters. It contains functions for parsing the Slurm environment variables in order to create configuration for distributed TF.
You need to have TensorFlow installed. All the examples were tested with TensorFlow 1.0.1, but other versions also have a good chance of working correctly.
To install execute the following on the command line:
git clone cd tensorflow_on_slurm sudo pip install .
A complete usage example using the CIFAR-10 dataset is included in the examples directory.
However if you just want to dive in you can paste the following snippet into your script:
import tensorflow as tf from tensorflow_on_slurm import tf_config_from_slurm cluster, my_job_name, my_task_index = tf_config_from_slurm(ps_number=1) cluster_spec = tf.train.ClusterSpec(cluster) server = tf.train.Server(server_or_cluster_def=cluster_spec, job_name=my_job_name, task_index=my_task_index)
It's possible that our tests don't cover all the corner cases about the names of the Slurm nodes etc. If you happen to spot some bugs please don't hesitate to file an issue here on github.
Pull request are more than welcome. If you'd like to add some new functionality don't forget to write unit tests for it and make sure you don't break any currently working tests (see below on how to run the tests)
