in the MOLPRO base directory. Most of the standard options for GNU make can be used safely; in particular, -j can be used to speed up compilation on a parallel machine. The program can then be accessed by making sure the bin/ directory is included in the PATH and issuing the command molpro. If MPI library is used for building Global Arrays or building MOLPRO directly, please be aware that some MPI libraries use mpd daemons to launch parallel jobs. In this case, mpd daemons must already be running before make.
