About

This repo is a holding area for configuration files used to configure/compile Abinit on clusters. Each configuration file contains a header with metadata in json format followed by the configure options supported by the Abinit build system. See files in the abiconfig/clusters directory.

The metadata section contains information such as the list of modules that must be loaded in order to configure/execute Abinit on the cluster, a brief description of the options activated and a list of keywords associated to the configuration file. For further information on the metadata section, see Contributing section.

The configuration file can be copied directly from this repository or, alternatively, one can install the package and use the abiconf.py script to search for ac files by hostname, by keywords. abiconf.py also provides commands to automate the configuration/make procedure and generate templates for job scripts (see Using abiconf.py). Contributions from users and sysadmins are welcome.

Note that abiconf.py is just a collection of configuration files and does not aim at becoming a package management tool for Abinit. If you need a real package manager able to support multiple versions and configurations of software, consider the following projects:

• spack
• easybuild

Both projects are designed for large supercomputing centers and they already provide configuration files to build Abinit.

Pre-compiled versions of Abinit for Linux and MacOSx are also available on the Abinit conda channel:

$ conda install abinit --channel abinit

These builds are useful especially if you want to try Abinit on your machine but they are not supposed to be used for high-performance calculations. For further information, please consult the abinit channel.

Getting abiconfig

From github

The developmental version is available at the github repo. Clone the repo with:

$ git clone https://github.com/abinit/abiconfig.git

After cloning the source, cd to the abiconfig directory and type:

$ python setup.py install --user

or

$ sudo python setup.py install

if you have root privileges on the machine.

Please fork the project on github, if you plan to contribute to abiconfig.

Using abiconf.py

Use:

$ abiconf.py hostname zenobe

to list the configuration files available for the zenobe machine. If the machine name is not provided, the full list of configuration files is printed.

Use:

$ abiconf.py keys intel mkl

to find the configuration files containing the keywords: intel and mkl and

$ abiconf.py keys

to get the full list of keywords.

Once you have found a configuration file for your machine in the abiconfig database (e.g. manneback-gcc-openmpi.ac), use:

$ abiconf.py workon manneback-gcc-openmpi.ac

to create the build directory, then follow the instructions reported on the terminal to configure and compile the code.

Note that workon must be executed within an Abinit directory tree containing the configure script.

It's also possible to generate a submission script template with the syntax:

$ abiconf.py script manneback-gcc-openmpi.ac

and print the ac file to terminal with:

$ abiconf.py show manneback-gcc-openmpi.ac

Use

$ abiconf.py doc

to get the documentation of the different options.

Use

$ abiconf.py --help

to get the list of available commands and

$ abiconf.py command --help

to list the options supported by command.

Contributing

Fork the repo and add your ac file to the clusters directory. Each configuration file must start with a metadata section enclosed between two --- markers. The text between the markers represents a dictionary in json format followed by the Abinit configure options in normalized form (remove the initial -- from the option name, replace - with _). Example:

#---
#{
#"hostname": "nic4",
#"author": "J. Doe",
#"date": "2016-09-30",
#"description": "Configuration file for nic4. Uses intel compilers, openmpi, mkl (sequential) and external netcdf4/hdf5",
#"keywords": ["linux", "intel", "openmpi", "mkl", "hdf5"],
#"qtype": "slurm",
#"pre_configure": [
#   "module purge",
#   "module load openmpi/1.7.5/intel2013_sp1.1.106",
#   "module load intel/mkl/64/11.1/2013_sp1.1.106",
#   "module load hdf5/1.8.13/openmpi-1.7.5-intel2013_sp1.1.106",
#   "module load netcdf/4.3.2/openmpi-1.7.5-intel2013_sp1.1.106"
# ]
#}
#---

# Abinit configure options in normalized form follows.

#install architecture-independent files in PREFIX
#prefix="~/local/"

# MPI/OpenMP
with_mpi_prefix="${MPI_HOME}"
enable_mpi="yes"
enable_mpi_io="yes"
enable_openmp="no"

# BLAS/LAPACK provided by MKL (dynamic linking)
# See https://software.intel.com/en-us/articles/intel-mkl-link-line-advisor
with_linalg_flavor="mkl"
with_linalg_libs="-L${MKLROOT}/lib/intel64 -lmkl_intel_lp64 -lmkl_core -lmkl_sequential -lpthread -lm -ldl"

If possible, try to avoid hard-coded values e.g. use ${MKLROOT} instead of the full path to the MKL library. The user is supposed to load the modules defined in the pre_configure section before running configure and the modules with automatically set these environment variables. The big advantage is that one link against a different MKL version by just changing the MKL module declared in the json dictionary.

The following keywords must be defined in the json dictionary:

• hostname

  The name of machine (mandatory). Prefer the short version over the long version e.g. use hmem instead of hmem.ucl.ac.be

• date

  Creation date in the format yyyy-mm-dd e.g. 2011-12-24 (mandatory)

• author

  The author of the configuration file (mandatory).

• description

  String or list of strings with info about the configuration file (mandatory)

• keywords

  List of strings with tags associated to the configuration file (mandatory). Use abiconf.py keys to get the list of keywords already used and try to re-use them for new files.

• pre_configure

  List of shell commands to be executed before configure. e.g. commands to load modules required to build/run the executables. Optional but highly recommended.

• post_configure

  List of shell commands to be executed after configure. Optional

• post_make

  List of shell commands to be executed after make. Optional

• qtype:

  String specifying the resource manager used by the cluster e.g. qtype: "slurm". Used by abiconf script command to generate a submission script template. Supported values: ["shell", "slurm", "pbspro", "sge", "moab", "bluegene"] Optional but highly recommended.

• qkwargs:

  Dictionary with the options that will be used to generate the template for the given qtype. Optional. qkwargs can be used to generate a template script that will work with the build specified by the ac file. For example manneback has different Slurm partions with nodes belonging to different intel families. The build defined in manneback-gcc-openmpi.ac is not compatible with the Harpertown/Nehalem nodes that must be excluded in the slurm script. To do so, we add:

      qkwargs": {"exclude": "mb-neh[070,201-212],mb-har[001-014],mb-har[101-116],mb-opt[111-116]"}
  

  to the json dictionary. The template generated by abiconf script manneback-gcc-openmpi-ac will contain:

      #SBATCH --exclude=mb-neh[070,201-212],mb-har[001-014],mb-har[101-116],mb-opt[111-116]
  

  See abiconfig.core.qtemplate for the list of options that can be specified for each qtype.
