4. If you have the AMD package of Davis, Duff and Amestoy, you can

|
|
|
|
specify --with-amd (see ./configure --help for more details).

The configure script will generate a Make.inc file suitable for
|
|
|
|
|
building the library.
|
|
|
|
|
The script is capable of recognizing the needed libraries with their
|
|
|
|
|
default names; if they are in unusual places consider adding the paths
|
|
|
|
|
with --with-libs, or explicitly specifying the names in --with-blas, etc.
|
|
|
|
|
Please note that a common way for the configure script to fail is to
|
|
|
|
|
specify inconsistent MPI vs. plain compilers, either directly or
|
|
|
|
|
indirectly via environment variables; e.g. specifying the Intel
|
|
|
|
|
compiler with FC=ifort while at the same time having an MPIFC=mpif90
|
|
|
|
|
which points to GNU Fortran.
|
|
|
|
|
The best way to avoid this situation is (in our opinion) to use the
|
|
|
|
|
environment modules package (see http://modules.sourceforge.net/), and
|
|
|
|
|
load the relevant variables with (e.g.)
|
|
|
|
|
module load gnu46 openmpi
|
|
|
|
|
This will delegate to the modules setup to make sure that the version
|
|
|
|
|
of openmpi in use is the one compiled with the gnu46 compilers.

SERIAL
|

|
|
|

|

|
Configuring with --enable-serial will provide a fake MPI stub library
|
|
|
|
|
that enables running in pure serial mode; no MPI installation is
|
|
|
|
|
needed in this case (but note that the fake MPI stubs are only
|
|
|
|
|
guaranteed to cover what we use internally, it's not a complete
|
|
|
|
|
replacement).

|

small cases have been tested but we do not offer full guarantee (yet).
