Wally Cluster

Preparation on the wally cluster

1. Get an account from Björn
2. Connect to wally-master (wally-master.cit.tu-berlin.de)
3. Setup your $JAVA_HOME variable to version 7 of Java in the ~/.bashrc file

Preparation in the ./aura-scripts/aura.sh file

• Adapt all paths. Namely the variables to update are:
  • USER
  • LOCAL_AURA_PATH
  • LOCAL_AURA_LOGS_DESTINATION
  • LOCAL_AURA_INPUT

Usage of the script

Usage: sh aura.sh {command} {wally_start} {wally_end}

• command

  • install: copies the aura project to the wally cluster and installs its maven dependencies (must be executed after the source code has been changed)
  • setup: prepares config files (must be executed each time AURA is started)
  • start: executes AURA
  • stop: stops the execution of AURA
  • cleanup: removes all measurement and log files (must be executed each time AURA is stopped)
  • kill: kills all processes of your user account (use this only in emergency situations, i.e. AURA won't stop executing)

• wally_start: the number of the first wally node to use (without leading zeros)

• wally_end: the number of the last wally node to use (without leading zeros)

HINT: Only a continuous range of wally nodes can be used with this script!
