Consider the following situation: The user has created a working directory for running the experiments, say MyJavaExperiments. This directory contains the following files.
R is started in the working directory. The following command starts SPOT's automatic tuning procedure.
> library(SPOT) > spot("cmaEs0.conf")Sometimes is it required to start a clean R session, because data from previous runs are in the workspace. Execute
rm(list=ls());to perform a cleanup before SPOT is loaded and run.
The output from Fig. 2 is shown by default during the tuning process.
The tuning process terminates with the following output:

A result file (RES), which contains important information from the tuning process, has been written to the working directory. It can be downloaded as cmaEs0.res from the workshop's web page.
