In order to build AMG4PSBLAS, the first step is to use the configure
script in the
main directory to generate the necessary makefile.
As a minimal example consider the following:
./configure --with-psblas=PSB-INSTALL-DIR
which assumes that the various MPI compilers and support libraries are available in
the standard directories on the system, and specifies only the PSBLAS install directory
(note that the latter directory must be specified with an absolute path). The full set of
options may be looked at by issuing the command ./configure --help
, which
produces:
‘configure’ configures AMG4PSBLAS 1.0.0 to adapt to many kinds of systems. Usage: ./configure [OPTION]... [VAR=VALUE]... To assign environment variables (e.g., CC, CFLAGS...), specify them as VAR=VALUE. See below for descriptions of some of the useful variables. Defaults for the options are specified in brackets. Configuration: -h, --help display this help and exit --help=short display options specific to this package --help=recursive display the short help of all the included packages -V, --version display version information and exit -q, --quiet, --silent do not print ‘checking ...’ messages --cache-file=FILE cache test results in FILE [disabled] -C, --config-cache alias for ‘--cache-file=config.cache’ -n, --no-create do not create output files --srcdir=DIR find the sources in DIR [configure dir or ‘..’] Installation directories: --prefix=PREFIX install architecture-independent files in PREFIX [/usr/local] --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX [PREFIX] By default, ‘make install’ will install all the files in ‘/usr/local/bin’, ‘/usr/local/lib’ etc. You can specify an installation prefix other than ‘/usr/local’ using ‘--prefix’, for instance ‘--prefix=$HOME’. For better control, use the options below. Fine tuning of the installation directories: --bindir=DIR user executables [EPREFIX/bin] --sbindir=DIR system admin executables [EPREFIX/sbin] --libexecdir=DIR program executables [EPREFIX/libexec] --sysconfdir=DIR read-only single-machine data [PREFIX/etc] --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com] --localstatedir=DIR modifiable single-machine data [PREFIX/var] --libdir=DIR object code libraries [EPREFIX/lib] --includedir=DIR C header files [PREFIX/include] --oldincludedir=DIR C header files for non-gcc [/usr/include] --datarootdir=DIR read-only arch.-independent data root [PREFIX/share] --datadir=DIR read-only architecture-independent data [DATAROOTDIR] --infodir=DIR info documentation [DATAROOTDIR/info] --localedir=DIR locale-dependent data [DATAROOTDIR/locale] --mandir=DIR man documentation [DATAROOTDIR/man] --docdir=DIR documentation root [DATAROOTDIR/doc/amg4psblas] --htmldir=DIR html documentation [DOCDIR] --dvidir=DIR dvi documentation [DOCDIR] --pdfdir=DIR pdf documentation [DOCDIR] --psdir=DIR ps documentation [DOCDIR] Program names: --program-prefix=PREFIX prepend PREFIX to installed program names --program-suffix=SUFFIX append SUFFIX to installed program names --program-transform-name=PROGRAM run sed PROGRAM on installed program names Optional Features: --disable-option-checking ignore unrecognized --enable/--with options --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no) --enable-FEATURE[=ARG] include FEATURE [ARG=yes] --enable-silent-rules less verbose build output (undo: "make V=1") --disable-silent-rules verbose build output (undo: "make V=0") --enable-dependency-tracking do not reject slow dependency extractors --disable-dependency-tracking speeds up one-time build --enable-serial Specify whether to enable a fake mpi library to run in serial mode. Optional Packages: --with-PACKAGE[=ARG] use PACKAGE [ARG=yes] --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no) --with-psblas=DIR The install directory for PSBLAS, for example, --with-psblas=/opt/packages/psblas-3.5 --with-psblas-incdir=DIR Specify the directory for PSBLAS C includes. --with-psblas-moddir=DIR Specify the directory for PSBLAS Fortran modules. --with-psblas-libdir=DIR Specify the directory for PSBLAS library. --with-ccopt additional [CCOPT] flags to be added: will prepend to [CCOPT] --with-fcopt additional [FCOPT] flags to be added: will prepend to [FCOPT] --with-libs List additional link flags here. For example, --with-libs=-lspecial_system_lib or --with-libs=-L/path/to/libs --with-clibs additional [CLIBS] flags to be added: will prepend to [CLIBS] --with-flibs additional [FLIBS] flags to be added: will prepend to [FLIBS] --with-library-path additional [LIBRARYPATH] flags to be added: will prepend to [LIBRARYPATH] --with-include-path additional [INCLUDEPATH] flags to be added: will prepend to [INCLUDEPATH] --with-module-path additional [MODULE_PATH] flags to be added: will prepend to [MODULE_PATH] --with-extra-libs List additional link flags here. For example, --with-extra-libs=-lspecial_system_lib or --with-extra-libs=-L/path/to/libs --with-blas=<lib> use BLAS library <lib> --with-blasdir=<dir> search for BLAS library in <dir> --with-lapack=<lib> use LAPACK library <lib> --with-mumps=LIBNAME Specify the libname for MUMPS. Default: autodetect with minimum "-lmumps_common -lpord" --with-mumpsdir=DIR Specify the directory for MUMPS library and includes. Note: you will need to add auxiliary libraries with --extra-libs; this depends on how MUMPS was configured and installed, at a minimum you will need SCALAPACK and BLAS --with-mumpsincdir=DIR Specify the directory for MUMPS includes. --with-mumpsmoddir=DIR Specify the directory for MUMPS Fortran modules. --with-mumpslibdir=DIR Specify the directory for MUMPS library. --with-umfpack=LIBNAME Specify the library name for UMFPACK and its support libraries. Default: "-lumfpack -lamd" --with-umfpackdir=DIR Specify the directory for UMFPACK library and includes. --with-umfpackincdir=DIR Specify the directory for UMFPACK includes. --with-umfpacklibdir=DIR Specify the directory for UMFPACK library. --with-superlu=LIBNAME Specify the library name for SUPERLU library. Default: "-lsuperlu" --with-superludir=DIR Specify the directory for SUPERLU library and includes. --with-superluincdir=DIR Specify the directory for SUPERLU includes. --with-superlulibdir=DIR Specify the directory for SUPERLU library. --with-superludist=LIBNAME Specify the libname for SUPERLUDIST library. Requires you also specify SuperLU. Default: "-lsuperlu_dist" --with-superludistdir=DIR Specify the directory for SUPERLUDIST library and includes. --with-superludistincdir=DIR Specify the directory for SUPERLUDIST includes. --with-superludistlibdir=DIR Specify the directory for SUPERLUDIST library. Some influential environment variables: FC Fortran compiler command FCFLAGS Fortran compiler flags LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a nonstandard directory <lib dir> LIBS libraries to pass to the linker, e.g. -l<library> CC C compiler command CFLAGS C compiler flags CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if you have headers in a nonstandard directory <include dir> MPICC MPI C compiler command MPIFC MPI Fortran compiler command CPP C preprocessor Use these variables to override the choices made by ‘configure’ or to help it to find libraries and programs with nonstandard names/locations.

For instance, if a user has built and installed PSBLAS 3.7 under the /opt
directory and is
using the SuiteSparse package (which includes UMFPACK), then AMG4PSBLAS
might be configured with:
./configure --with-psblas=/opt/psblas-3.7/ \ --with-umfpackincdir=/usr/include/suitesparse/
Once the configure script has completed execution, it will have generated the file
Make.inc
which will then be used by all Makefiles in the directory tree; this file will be
copied in the install directory under the name Make.inc.AMG4PSBLAS
.
To use the MUMPS solver package, the user has to add the appropriate options to
the configure script; by default we are looking for the libraries -ldmumps -lsmumps
-lzmumps -lcmumps -mumps_common -lpord
. MUMPS often uses additional
packages such as ScaLAPACK, ParMETIS, SCOTCH, as well as enabling OpenMP; in
such cases it is necessary to add linker options with the --with-extra-libs
configure
option.
To build the library the user will now enter
make
followed (optionally) by
make install
