Site configuration for WIEN97
At the end of expand_lapw you will be prompted to start the
script
./siteconfig_lapw
When you start this script for the first time (file
INSTALLDATE not present), you will be guided through the setup
process.
Later on you can use siteconfig_lapw to redimension
parameters and recompile the respective programs.
During the first run, you will be asked to specify:
- your system; at this point system specific files (e.g.
cputim.f as well as some files containing code which is known
to perform better on your system than the default) will be
installed. If your system is not listed, use the system
generic, which should compile on any machine.
- your FORTRAN77 compiler; just in case you are not using the
default f77
- your compiler and linker options as well as the place for LAPACK
and BLAS libraries. Depending on the system you selected, we have
included some recommended compiler and linker options, which are
known to work on our systems (use generic when you have
problems here; see also sec. 11.2.4). On some systems
it is required to specify LAPACK and BLAS libraries twice (i.e.
R_LIBS:-llapack_lapw -lblas_lapw -llapack_lapw -lblas_lapw).
- configration of parallel execution will ask whether your system
is shared memory, so that set default parameters can be set
accordingly ( $WIENROOT/parallel_options is the file where
this information is stored).
- to configure parallel execution for distributed systems, specify
the command to open a remote shell, which on most systems is
rsh ( unfortunately some systems have a different name, e.g.
on HPs this command is called remsh).
- You can optionally change dimensioning parameters. The list of
parameters taken from file param.inc_r (real version) and
param.inc_c (complex version) from SRC_lapw1.
Changing parameters with siteconfig_lapw will change that
parameter in all subdirectories.
- Now you are prompted to compile all programs (this will be done
using make) and the executables are copied to the rootwien
directory.
Compilation might take quite some time. After compilation you will
find a file compile.msg in each SRC_* directory.
