clusterfork | a simple , self-contained parallel shell for clusters

clusterfork is a Perl library. clusterfork has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

clusterfork (aka cf) is a commandline perl script for issuing the same command to many computers simultaneously via ssh, collating the results of that command by node, and presenting those results to the user in a number of ways to judge whether it has been successful. It can be scripted as well as used interactively, logging the usual output. For example, the following line will show you the correctable and uncorrectable memory errors on the nodes 10.255.78.20 thru 10.255.78.60. Change the IP range to your own and try it yourself. Obviously, the machines have to be using the [EDAC system]. clusterfork --target=10.255.78.[20:60] cd /sys/devices/system/edac/mc \ && grep [0-9]* mc*/csrow*/[cu]e_count.
