Show how to use multiple GPUs with Tensorflow by modifying the example tf_test.py

• tf_test_multi_gpu.py: Modified code tf_test.py to use all available GPUs on a node
• run.sbatch: Slurm batch-job submission script to pull singularity image and run tf_test_multi_gpu.py
• tf_test.out: Output file

1. In this example the slurm batch script pulls a singularity container with TensorFlow and runs the examples inside the singularity container. However, you can modify run.sbatch script to run within a conda/mamba environment.
