View source for BitTorrent (B. Cohen's version)

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
* Stick the torrent file into $HOME/public at the frontend.
** It is then available from within G5K under http://public.lille.grid5000.fr/~kdichev/{torrent file}
* Start the tracker on the frontend:
  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
