Cluster Administrators' ssh Wrapper
- classh is yet another wrapper around ssh for running jobs on multiple
targets. It can support tens of thousands of targets (tested on over 25,000 at once) and runs a configurable number of jobs concurrently. It separately gathers results, output and error messages, displaying summary/status information it comes in (asynchronously) and more detailed data after all jobs have completed.
classh provides an SSHJobMan class which can be imported into your own Python code and easily used to handle specialized display or other disposition of results. (For example the names of all hosts on which the job succeeded can be fed into another process while various failure modes can be tested and fed into other processes).
Download the file for your platform. If you're not sure which to choose, learn more about installing packages.
