This script is used to start a job server manually for running ensemble-based jobs in a parallel distributed computing environment. The utilities ensmin.pl, enslatsim.pl, ensrun.pl may then be used as clients by giving the server host, port and ID through their -rserv option.
Starting the job server manually is most useful when remote execution via rsh is not possible in a distributed environment. Otherwise the -hosts option for the ensemble utilities is a more convenient way since it will start the server automatically and submit clients via rsh.
This utility requires the tag name of the ensemble structures as argument. Additional options are available to select the ensemble directory (-dir), the desired runs for which a job list should be created (-runs), the property that is used for identifying which jobs need to be run (-use, by default: etot), and to request a log file with -log.
The script writes to standard output the host name, port, and server ID in the format expected by the client -rserv option. Since the script waits for the server to exit after spawning a new process for the server it is recommended to start the script in the background with &.
