Appendix: Manual installation from sources
Note: This section is not necessary if the installation via Spack has been completed. It contains everything what Spack does automatically for you.
As an alternative to Spack, pfd-parallel and its dependencies can also be compiled directly. For most users, a Spack installation should suffice, in which case this section should be skipped.
For the various dependencies, it is recommended to create a file that exports the various install locations as environment variables. For this purpose, the following command may be run at a convenient location, after which the resulting file should be edited to specify two directory roots, one for purposes of compilation and one for installation of the code. While the first should typically be a fast local file system, the second must be accessible from all computation nodes to be used for running the system.
cat > env_vars_pfd.txt << "EOF"
export software_ROOT=<software-root>
# Some fast location in local system for hosting build directories,
# for example, something like /tmpbig/$USER/pfd-parallel or just $HOME/pfd-parallel if the user has a
# fast home directory.
export install_ROOT=<install-root>
# The install root is recommended to be some network (nfs) mountpoint, where
# each node of the cluster should be able to read from, for example
# something like /scratch/$USER/pfd-parallel
export compile_ROOT=$software_ROOT
# Optionally, this might be set to something like /dev/shm/$USER/pfd-parallel that
# stores files purely in memory, thus the contents of this
# location will be lost after reboot. It can speed up the computation times, as
# all disk io becomes memory io.

As it is currently structured, the user needs only fill in the <software-root>
and the <install-root>, then all other veriables are set relative to these.
The above structure can of course be altered to suite the compiler's setup,
as long as the scripts in this REAME are altered accordingly, since they assume
the directory structure.
Once all the locations have been set correctly, the variables can easily be
exported with the following call:
source env_vars_pfd.txt
Ensure that the compile and install roots exist:
mkdir -p $software_ROOT
mkdir -p $install_ROOT
mkdir -p $compile_ROOT
GPI-Space targets and has been successfully used on x86-64 Linux systems. Other architectures are not guaranteed to work properly at this point.
The virtual memory layer can be backed with either Ethernet, Infiniband or BeeOND.
GPI-Space supports multiple Linux distributions:
- Centos 6
- Centos 7
- Centos 8
- Ubuntu 18.04 LTS
- Ubuntu 20.04 LTS
Ensure that the GPI_ROOT_DIR exists:
mkdir -p $GPI_ROOT_DIR

| libssh2 | >= 1.7 |
libssh2 is not built with the OpenSSL backend on all systems. Additionally,
some versions available via package manager might not be compatible with
OpenSSH's default settings. For those reasons, it is highly recommended to build
libssh2 1.9 from scratch. Doing so is however straightforward thanks to CMake.
As additional dependencies OpenSSL and Zlib are required (for this any
package manager version should be sufficient). Also, unless Libssh2_ROOT is
set to /usr, the LD_LIBRARY_PATH needs to be set (as in lines 2 and 3 below)
in order for applications to find the correct one.
WARNING:
- libssh2 1.7 is not compatible with OpenSSL >= 1.1.
- libssh2 <= 1.8 is incompatible with the new default SSH-key format in OpenSSH >= 7.8.

The code listings in this document assume
-
${GPISPACE_REPO}to be the directory storing the GPI-Space sources. -
${GPISPACE_BUILD_DIR}to be an empty directory to be used for building GPI-Space. -
${GPISPACE_INSTALL_DIR}to be a directory to install GPI-Space to. It is suggested to use a previously empty directory on a shared filesystem. -
${GPISPACE_TEST_DIR}to be an empty directory on a shared filesystem, which used when running the system tests.
Start by cloning gpi-space:
cd $GPI_ROOT_DIR
mkdir gpispace && cd gpispace
git clone \
--depth 1 \
--branch v22.03 \
https://github.com/cc-hpc-itwm/gpispace.git \
gpispace
Should you want to build the tests, run the following command. Note, the tests significantly increase build time, so an experienced user who has built gpi-space on a given machine before might opt not to run to define the build_tests variable.
export build_tests="-DBUILD_TESTING=on
-DSHARED_DIRECTORY_FOR_TESTS=$SHARED_DIRECTORY_FOR_TESTS"
mkdir -p $SHARED_DIRECTORY_FOR_TESTSTo build GPI-Space, run
mkdir -p "${GPISPACE_BUILD_DIR}"

NOTE:
GPI-Space requires a working SSH environment with a password-less SSH-key when using the SSH RIF strategy. To ensure this, make sure when generating your ssh keypair to leave the password field empty.
NOTE:
GPI-Space requires a working SSH environment with a password-less SSH-key when using the SSH RIF strategy, the default for most applications.
By default,
${HOME}/.ssh/id_rsais used for authentication. If no such key exists,ssh-keygen -t rsa -b 4096 -N '' -f "${HOME}/.ssh/id_rsa" ssh-copy-id -f -i "${HOME}/.ssh/id_rsa" "${HOSTNAME}"can be used to create and register one.
The following is a simple self test, that should be sufficient for most users.
# to test with multiple nodes, set GSPC_NODEFILE_FOR_TESTS
# Slurm: export GSPC_NODEFILE_FOR_TESTS="$(generate_pbs_nodefile)"
# PBS/Torque: export GSPC_NODEFILE_FOR_TESTS="${PBS_NODEFILE}"
# and SWH_INSTALL_DIR:
# export SWH_INSTALL_DIR=<a-shared-directory-visible-on-all-nodes>
"${GPISpace_ROOT}/share/gspc/example/stochastic_with_heureka/selftest"If GPI-Space has been built with testing enabled, then ctest can be
used to execute the unit- and system tests. It can be ommitted, but is
recommended for first time installations.
cd "${GPISPACE_BUILD_DIR}"
export GPISPACE_TEST_DIR=$SHARED_DIRECTORY_FOR_TESTS # any empty test directoy should be good

Some of these tests take a long time (811 seconds on Intel i7), and there are 294 tests in the suite at the time of writing this document.
It is recommended to install the current version of Singular, which will be required by our framework. The version of Singular found in package manager does not generally work with the PFD project.
Besides flint, Singular has various more standard dependencies, which are usually available through the package manager of your distribution. Feel free to refer to the step-by-step instructions to build Singular for more details, taking note of the tools necessary to compile Singular under point 1.b.
This document gives a thorough guide for building the various dependencies and
then finally Singular itself, all the while assuming the user does not have
sudo/root privileges. This guide assumes that mpfr and gmp are installed
by the package manager to /usr
Start by choosing a location where Singular can be cloned. This will be
indicated by $SING_ROOT and compile the various dependencies
mkdir -p $SING_ROOT
The official guides for singular clones the latest development branch of flint. As flint is being actively developed and the APIs changed quite often, this has led to issues in the past. Therefore, it is rather recommended that a release version be downloaded and compiled instead. The newest release with which Singular can be built (at the time of writing) is version 2.6.3.

The PFD project can now be compiled and installed.
The following environment variables must be set:
-
${GPISPACE_REPO}The path to the repository cloned from Github. This is needed for some cmake scripts, amongst other reasons. -
${GPISPACE_INSTALL_DIR}The install prefix used when compiling and installing gpi-space above. -
${SINGULAR_INSTALL_DIR}The install prefix used when compiling and installing Singular above. -
${PFD_REPO}The root of the cloned PFD project. -
${PFD_BUILD_DIR}The path of the build directory. It is recommended to build in a separate directory to the source code, preferably starting with an empty build directory. -
${PFD_INSTALL_DIR}The path to where the PFD project should be installed.

Assuming that we are installing on a Ubuntu system (analogous packages exist in other distributions), we give installation instructions for standard packages which are required by the framework and may not be included in your of-the-shelf installation.
Note that the following requires root privileges. If you do not have root access, ask your administator to install these packages. You may want to check with dpkg -l <package name> whether the package is installed already.
