How to use the parallel version

For starting the calculations in parallel, the switch -p was implemented in the scripts x, run_lapw and runsp_lapw. In addition to the -p switch the file .machines has to be present in the current work directory.

In this file the machine names on which the parallel processes should be launched, and their respective, relative speeds must be specified.

Generation of all necessary files, starting of the processes and summation of the results is done by the appropriate scripts lapw1para, lapwsopara and lapw2para, which are called automatically when the -p switch in x lapw1/2/so -p is specified.

If the .machines file does not exist, the serial versions of lapw1, lapwso and lapw2 are executed.
