Jobserver.pl
Usage
usage: jobserver.pl [options] tag options: [-dir workdir] [-runs [from:]to] [-use proptag] [-log logfile]
Description
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/ssh 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/ssh.
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 &.

jobserver.pl -dir data -runs 50 vacmin &

in the ensemble stored under the data directory. The joblist
is generated for missing structures up to run index 50.
