Making RPM for the dacapo python interface
``````````````````````````````````````````

Start by checking the new version out from cvs::
 
     cvs co dacapo/Python
     cd dacapo/Python

Update the setup.py with the new version number and build the rpm using::

     python setup.py bdist_rpm

If you need to build a new release of the same version you can add the keyword `--release 2`
after `bdist_rpm`.

The new architecture independent RPM will be in::

     build/bdist.linux-i686/rpm/RPMS/Dacapo-0.10-1.noarch.rpm

Now build the rpm using the spec file in `/home/camp/rpmbuild/SPECS/campos-dacapo-opteron.spec`,
remember to update version and revions numbers in the spec file::

     rpmbuild -bb campos-dacapo-opteron.spec

Cluster software

Cloning of nodes

The NIFLHEIM cluster uses the SystemImager toolkit on a central server to create an image of a Golden Client node that has been installed in the usual way using a distribution on CD-ROM (Centos Linux in our case). The SystemImager is subsequently used to install identical images of the Golden Client on all of the nodes (changing of course hostname and network parameters).

NetCDF (network Common data Form)

NetCDF (network Common Data Form) is an interface for array-oriented data access and a library that provides an implementation of the interface. The NetCDF library also defines a machine-independent format for representing scientific data.

NetCDF is installed on the cluster via the rpm netcdf-3.6.1-1.2.el4.fys. This build includes bindings to the PathScale fortran compiler. A locally developed spec file for the NetCDF rpm is in:

~rpmbuild/SPECS/netcdf.spec

OpenMPI (A High Performance Message Passing Library)

OpenMPI is an open source implementation of the MPI message passing standard.

The version now installed is 1.1.1 and is build with support for:

* Torque (installation in /usr/local)
* gcc c compiler
* pathscale fortran compiler

The version on the cluster is installed using the rpm openmpi-1.1.1-2. This rpm is build using the buildrpms.sh script from the page.

This is done by modifying the buildrpms.sh script. Change the following lines:

prefix="/usr/local"
configure_options="--with-tm=/usr/local FC=pathf90 F77=pathf90"

buildrpms.sh is used to build one single rpm, including man pages:

build_srpm=no
build_single=yes
build_multiple=no

The build of multiple rpms did not seem to work in version 1.1.1.

buildrpms.sh needs the rpm spec file, this can be copied from the unpacked openmpi tar file:

cp openmpi-1.1.1/contrib/dist/linux/openmpi.spec .

Now run:

./buildrpms.sh openmpi-<version>.tar.gz

Processor affinity

For some parallel libraries like BLACS and ScaLAPACK which are using OpenMPI as the communication layer, setting processor affinity seems to be important. Processor affinity is when a process is fixed on a specific processor, see more details in this OpenMPI FAQ.

To enable processor affinity use:

mpirun --mca mpi_paffinity_alone 1 -np 4 a.out

Without this option all copies of the parallel program (siesta) would land on one CPU.

Dacapo

Making RPM for the dacapo python interface

Start by checking the new version out from cvs:

cvs co dacapo/Python
cd dacapo/Python

Update the setup.py with the new version number and build the rpm using:

python setup.py bdist_rpm

If you need to build a new release of the same version you can add the keyword --release 2 after bdist_rpm.

The new architecture independent RPM will be in:

build/bdist.linux-i686/rpm/RPMS/Dacapo-0.10-1.noarch.rpm

Building RPM for Opteron nodes

Follow the steps for compiling dacapo on the opteron nodes, end with:

gmake pathscale MP=mpi
gmake pathscale

Now make a tar file of the directory campos-dacapo-<version> and place this in the rpm source directory:

cd ..
tar zcf /home/camp/rpmbuild/SOURCES/campos-dacapo-<version>-opteron.tar.gz campos-dacapo-<version>

Now build the rpm using the spec file in /home/camp/rpmbuild/SPECS/campos-dacapo-opteron.spec, remember to update version and revions numbers in the spec file:

rpmbuild -bb campos-dacapo-opteron.spec
