Manual software installation¶

IGWN software is distributed through a variety of mechanisms, with principal support aimed at providing binary distributions for the LIGO Data Grid grid computing sites.

The following platforms have first-class support:

• Conda (conda-forge)
• Scientific Linux 7

The following platforms have best-effort support:

• Debian (alternative)

The following platforms were supported in the past, but have now been dropped:

• Debian 9 (stretch)
• Debian 8 (jessie)
• MacPorts

Conda (conda-forge)¶

A large number of IGWN software packages are available as Conda packages via the Conda-forge organisation.

Installing packages from conda-forge¶

To install a conda-forge package into an existing conda environment:

conda config --add channels conda-forge
conda install <package-name>

Scientific Linux 7¶

To configure yum to use the LSCSoft repositories:

Configuring the lscsoft-production repository¶

Download the configuration RPM for the production LSCSoft repository

wget http://software.ligo.org/lscsoft/scientific/7/x86_64/production/l/lscsoft-production-config-1.3-1.el7.noarch.rpm

Check that the SHA256 checksum matches the following:

7b250f9148ba88617fb6494390c871557d3b519252f8eafc5e6aa62cecae6b4b

Install the RPM:

rpm -ivh lscsoft-production-config-1.3-1.el7.noarch.rpm

Clear the yum cache and initialise the repository:

yum clean all
yum makecache

The system should now be configured to track the LSCSoft Production repository. The repository configuration itself is managed via packages in the LSCSoft repository so any updates will automatically be installed using the standard package update process.

Configuring other SL7 repositories¶

Now that the system is tracking the production repository it can be configured to track the other repositories required to install IGWN software:

yum install lscsoft-backports-config
yum install lscsoft-epel-config
yum install lscsoft-grid-config

If you want a newer git version then enable the WANdisco-git repository, add the following contents:

[wandisco-git]
name=Wandisco GIT Repository
baseurl=http://opensource.wandisco.com/centos/7/git/$basearch/
enabled=1
gpgcheck=1
gpgkey=http://opensource.wandisco.com/RPM-GPG-KEY-WANdisco

Debian 9 (stretch)¶

Configuring the lscsoft Debian repository¶

To add the LSCSoft Debian repository to your system, create /etc/apt/sources.list.d/lscsoft.list with the following content:

deb http://software.ligo.org/lscsoft/debian stretch contrib
deb-src http://software.ligo.org/lscsoft/debian stretch contrib

Configuring the lscsoft-testing Debian repository¶

To add the LSCSoft testing Debian repository to your system, create /etc/apt/sources.list.d/lscsoft-testing.list with the following content:

deb http://software.ligo.org/lscsoft/debian stretch-proposed contrib
deb-src http://software.ligo.org/lscsoft/debian stretch-proposed contrib

Debian (alternative)¶

The group at AEI-Potsdam-Golm provide debian package builds, and provide access to those builds in a "flat" (and unsigned) repository, one directory per platform (architecture x distribution). These repositories also provide selected gridtools.

Debian users can configure that repository as an extra package source.

apt-get install ca-certificates
apt-get install apt-transport-https

To use the alternative Debian package source, create /etc/apt/sources.list.d/lscdebian.list with the following content:

deb [trusted=yes] https://hypatia.aei.mpg.de/lsc-{arch}-{dist} ./

where {arch} can be one of

• amd64,
• arm64,
• i386,
• powerpc,
• ppc64el,

and {dist} one of

• jessie,
• stretch,
• buster.

For example:

deb [trusted=yes] https://hypatia.aei.mpg.de/lsc-amd64-buster/ ./

deb [trusted=yes] https://hypatia.aei.mpg.de/lsc-i386-stretch/ ./

Once this is configured, run

apt-get update

to make the new package source available to APT.

To check that this configuration works, you should be able to search for IGWN-internal packages, e.g. python3-lal:

# apt-cache policy python3-lal
python3-lal:
  Installed: (none)
  Candidate: 6.20.2-1+deb10u0
  Version table:
     6.20.2-1+deb10u0 500
