Install Xmipp¶

• Download the v2.3 source code from http://xmipp.cnb.csic.es/twiki/bin/view/Xmipp/InstallingTheSoftware
• Go into Xmipp source directory
• Find openmpi directory

$ locate libmpi.so

/usr/lib/openmpi/1.2.7-gcc/lib/libmpi.so

• Setup Xmipp to use openmpi by changing three lines in SConstruct

$ cp SConstruct SConstruct.orig
$ vi SConstruct

opts.Add('MPI_INCLUDE', 'MPI headers dir ', '/usr/lib/openmpi/1.2.7-gcc/include/')
opts.Add('MPI_LIBDIR', 'MPI libraries dir ', '/usr/lib/openmpi/1.2.7-gcc/lib/')
opts.Add('MPI_LIB', 'MPI library', 'mpi')

• Compile

$ sudo mpi-selector --yes --system --set `rpm --qf '%{NAME}-%{VERSION}-gcc-%{ARCH}\n' -q openmpi`
$ export PATH=$PATH:/usr/lib/openmpi/1.2.7-gcc/bin
$ ./scons.configure

• Look for the following line in the output:

* Checking for MPI ... yes

$ ./scons.compile
