[Wien] siteconfig MPI_REMOTE

[Gavin Abo]

I'm confused about the parallel setup behavior of the Wien2k 12.1 
siteconfig_lapw script.

The message in siteconfig seems to indicate that if "y" is used for 
shared memory, then MPI_REMOTE = 0 (which can only be changed by editing 
the parallel_options file directly).  However, the script gives a prompt 
to input whether the user wants to use 0 or 1.  If the user presses 
enter without giving input, it outputs MPI_REMOTE = " ". On the other 
hand, MPI_REMOTE = "1 " is the output in parallel_options regardless if 
0 or 1 is used as input along with some possibly unwanted quotation marks.

The mpi-2 message suggests but does not imply that MPI_REMOTE = 0 is the 
default (when no input is given), but MPI_REMOTE = 1 is the default in 
the script.

I believe the prompt to select MPI_REMOTE = 0 or 1 is useful when "n" is 
used for shared memory.  However, the script always sets MPI_REMOTE = 1. 
The relevant sections of code should be between lines 852-873. So the 
Wien2k developers may want to check if the script is performing as intended.
