The modified bittorrent tarball is currently under the MPIBlib repository:

svn co https://hcl.ucd.ie/repos/CPM/trunk/MPIBlib/tests/bittorrent/bittorrent.tar.gz

  • Extract this under your home directory
    • You might need
 mv $HOME/lib/python $HOME/lib/python2.6
  • export following variables to tweak the way Python paths are searched:
 export PYTHONHOME=$HOME
 export PYTHONPATH=/usr/lib/python2.6/
  • Modify logfile path in /home/kdichev/lib/python2.6/BitTorrent/StorageWrapper.py
  • Create a file of any size consisting of "s" characters only.
  • Create torrent file:
 btmakemetafile myfile.ext http://<frontend on G5K>:6969/announce
 bttrack --port 6969 --dfile dstate
  • Book nodes interactively:
 qsub -I -lnodes=...
  • Start one client that has the full copy
 ssh <one-node> btdownloadheadless --url http://public.lille.grid5000.fr/~kdichev/{torrent file} &
  • On all other nodes, launch the client at the same time:

script-per-process.sh

 #!/bin/bash
 cd /tmp ;  btdownloadheadless --display_interval 100 --url http://public.lille.grid5000.fr/~kdichev/{torrent file}

run.sh

 mpirun -n 14 --machinefile hostfile  $PWD/script-per-process.sh
