Typical script (one of the Viktor's many) that allows user to run a set of tasks or processes (e.g. named 'strt_e10') feeding different parameters into each task. It also stores useful information in a log-file that relates to the individual process. This is especially useful if one runs the same code simultaneously on many nodes and/or machines, as it allows user to identify PID and the hostname for the specific process. Extra lines can be added for the script to produce more information about the process.
