Main commands for running LEPTON (on a Linux host)

LEPTON's source code is 100% Java code. It can therefore run on any platform featuring a standard JRE (Java Runtime Environment).

This code is however distributed with a bash script lepton.sh (located in $LEPTON_HOME/bin) that makes it easy to start and stop LEPTON on a Linux host.

Usage: ./bin/lepton.sh <command> [option]*

With command:
    info|status|start|stop|clean|start_node|stop_node|exec

To display help about the commands:   ./bin/lepton.sh -h <command>
   about the default configuration: ./bin/lepton.sh -h info

Starting or stopping LEPTON

lepton.sh start
lepton.sh stop

Note that although several LEPTON instances could run concurrently on the same host, the bash script lepton.sh has been designed so that only one experiment shall be conducted at any time on a host platform.

Checking if LEPTON is running

lepton.sh status

Cleaning the log directory

lepton.sh clean

By default the log directory is /dev/shm/${USER}/lepton. This can be changed by modifying parameter log_dir (see below).

Displaying the current configuration parameters

lepton.sh info

Adjusting configuration parameters when starting LEPTON

lepton.sh start [<key>=<value>]* [conf=<config_file>]*
