## Example start_mount_code for the w-iLab.t tutorial
## In the example, I set up a network with one "coordinator" node and several other nodes.  The behavior of my nodes
## is determined by my own program, called "custombin", which can take "coordinator" or "regular" as an argument, 
## depending on whether the node has a certain "coordinator" role (e.g. a node with a full view on the network) or not.
##
## In the example below, inode003 is configured as a coordinator, inode004 does nothing but reporting that it is inode004,
## all other nodes that are in included in my experiment will behave as "regular" nodes.


## WHAT TO DO AS A COORDINATOR NODE
if [ `hostname` == "inode003" ]; then

        echo "I am the coordinator" >> /tmp/log/mylogfile.txt
        echo `date` "Starting my custom binary..." >> /tmp/log/mylogfile.txt
	
	## Below, I start my own "custombin" binary (available under my iPlatform subdirectory) with argument coordinator
	## custombin needs custom libraries that I included in my own "libs" folder under my iPlatform folder

        LD_LIBRARY_PATH=~/iPlatform/libs:$LD_LIBRARY_PATH /tmp/mnt/custombin coordinator &> /tmp/log/outputofCustombin.txt &



## WHAT TO DO AS ANOTHER SPECIAL ROLE
elif [ `hostname` == "inode004" ]; then
        
        echo "I am inode004" >> /tmp/log/mylogfile.txt

## WHAT TO DO AS ANY OTHER NODE
else
        echo "I am an ordinary node." > /tmp/log/log.txt
	## I want the ordinary nodes to start a bit later compared to the coordinator node
        sleep 45
        echo `date` "Starting my own program" >> /tmp/log/mylogfile.txt
        LD_LIBRARY_PATH=~/iPlatform/libs:$LD_LIBRARY_PATH custombin regular &> /tmp/log/mylogfile.txt &
