+== Running jobs with GPU ==
+Discovery has 12 GPU nodes: g01-g12. To submit a job to these nodes, you will need to specify with 
+{{{
+#!sh
+#SBATCH --partition gpuq
+#SBATCH --gres=gpu:1
+}}}
+where `1` means to use 1 GPU.
+
+== Use DeepXDE ==
+
+Discovery supports container by a software called `singularity`, see the full document: [https://docs.sylabs.io/guides/3.5/user-guide/index.html]
+A precompiled DeepXDE image with `Tensorflow v.2` backend is available at `docker://chenggongdartmouth/deepxde:v1.2`
+
+Before using this image, you will need to make sure you have 
+{{{
+{"backend": "tensorflow"}
+}}}
+in your  `~/.deepxde/config.json`.
+
+The following is an example of using DeepXDE to run a script`./test.py` on discovery: 
+{{{
+#!sh
+#!/bin/bash
+#SBATCH --job-name=testDeepxde
+#SBATCH --account=ice
+#SBATCH -o testdeepxde.outlog
+#SBATCH -e testdeepxde.errlog
+#SBATCH --nodes=1
+#SBATCH --ntasks-per-node=4
+#SBATCH --time=0-05:00:00
+#SBATCH --mem=32G
+#SBATCH --partition gpuq
+#SBATCH --gres=gpu:1
+#SBATCH --mail-type=END,FAIL
+
+cat ./test.py | singularity exec docker://chenggongdartmouth/deepxde:v1.2 python
+}}}
