This package provides parallel versions of the openssh tools. Included in the distribution:

  • Parallel ssh (pssh)
  • Parallel scp (pscp)
  • Parallel rsync (prsync)
  • Parallel nuke (pnuke)
  • Parallel slurp (pslurp)

What are these tools good for? Mainly for controlling large collections of nodes in the wide-area, where faster alternatives such as GEXEC and PCP are not available. For example, I use these tools on a fairly routine basis on PlanetLab to control hundreds of machines spread around the world.
