taktuk 3.7.3-3ubuntu1 (powerpc binary) in ubuntu precise

 TakTuk allows to execute commands in parallel on a potentially large set of
 remote nodes (using ssh to connect to each node). It is typically used inside
 high performance computing clusters and grids. It uses an adaptive algorithm
 to efficiently distribute the work and sets up an interconnection network to
 transport commands and perform I/Os multiplexing. It doesn't require any
 specific software on the nodes thanks to a self-propagation algorithm.
