openmpi magic

I have just rebuilt openmpi-1.3.4 for use with CASTEP. This is built to a useful /opt location with Torque, F90 support for gfortran44.

gLite support for OPENMPI is fairly generic and means any openmpi rpm install does not have any useful batch or interconnect support. So anything out of the ordinary requires a custom build.

I will stick the RPM available for download here in the next few days.

The magic for building from a src rpm:

cd /usr/src/redhat/SPECS/
rpmbuild -ba --define '_prefix /opt/openmpi-1.3.4' --define '_mandir %{_prefix}/share/man'
--define 'configure_options --prefix=/opt/openmpi-1.3.4 --with-tm=/usr/
FC=gfortran44 F77=gfortran44 CC=gcc44 CXX=g++44 FFLAGS=-O2 FCFLAGS=-O2 CFLAGS=-O2 CXXFLAGS=-O2'
openmpi-1.3.4.spec
