## Running ## Running
Before POET is ready to run, a working directory must be created. In this
directory you should find the executable file, the R scripts
`<POET_ROOT>/R_lib/kin_r_library.R` and `<POET_ROOT>/R_lib/parallel_r_library.R`
and the simulation description e.g. `<POET_ROOT>/data/chem_problems/SimDol2D.R`.
Run POET by `mpirun ./poet <OPTIONS> <SIMFILE> <OUTPUT_DIRECTORY>` where: Run POET by `mpirun ./poet <OPTIONS> <SIMFILE> <OUTPUT_DIRECTORY>` where:
