  A software for managing simulation jobs and results, named "OACIS", is
presented. It controls a large number of simulation jobs executed in various
remote servers, keeps these results in an organized way, and manages the
analyses on these results. The software has a web browser front end, and users
can submit various jobs to appropriate remote hosts from a web browser easily.
After these jobs are finished, all the result files are automatically
downloaded from the computational hosts and stored in a traceable way together
with the logs of the date, host, and elapsed time of the jobs. Some
visualization functions are also provided so that users can easily grasp the
overview of the results distributed in a high-dimensional parameter space.
Thus, OACIS is especially beneficial for the complex simulation models having
many parameters for which a lot of parameter searches are required. By using
API of OACIS, it is easy to write a code that automates parameter selection
depending on the previous simulation results. A few examples of the automated
parameter selection are also demonstrated.
