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.
ノードが多いときに便利そう。
