+# Documentation
+# This bash file takes three inputs. The first argument (nfs_home) is the path to the nfs home directory.
+# The second one (python_bin) is the path to the python bin folder.
+# The last argument (logs_subfolder) is the path to the logs folder with respect to the nfs home directory.
+#
+# The nfs home directory should contain the code of this framework stored in $nfs_home/decentralizepy and a folder
+# called configs which contains the file 'ip_addr_6Machines.json'
+# The python bin folder needs to include all the dependencies of this project including crudini.
+# The results will be stored in $nfs_home/$logs_subfolder
+# Each of the experiments will be stored in its own folder inside the logs_subfolder. The folder of the experiment
+# starts with the last part of the config name, i.e., for 'config_celeba_topkacc.ini' it will start with topkacc.
+# The name further includes the learning rate, rounds and batchsize as well as the exact date at which the experiment
+# was run.
+# Example: ./run_grid.sh  /mnt/nfs/wigger /mnt/nfs/wigger/anaconda3/envs/sacs39/bin /logs/celeba
+#
+# Additional requirements:
+# Each node needs a folder called 'tmp' in the user's home directory
+#
+# Note:
+# - The script does not change the optimizer. All configs are writen to use SGD.
+# - The script will set '--test_after' and '--train_evaluate_after' such that it happens at the end of a global epoch.
+# - The '--reset_optimizer' option is set to 0, i.e., the optimizer is not reset after a communication round (only
+#   relevant for Adams and other optimizers with internal state)
+#
+# Addapting the script to other datasets:
+# Change the variable 'dataset_size' to reflect the data sets size.
+#
+# Known issues:
+# - If the script is started at the very end of a minute then there is a change that two folders are created as not all
+#   machines may start running the script at the exact same moment.
