What is the XSEDE National Integration Toolkit (XNIT), and how do I use it?
The XSEDE National Integration Toolkit (XNIT; formerly known as the XSEDE Yum Repository) is a collection of Red Hat Package Manager (RPM) packages assembled to simplify the process of converting a "bare-bones" Linux cluster into a high-performance, parallel computing system that can be used to support scientific discovery. The XNIT packages include specific versions and builds of scientific, mathematical, and visualization applications recommended by the Extreme Science and Engineering Discovery Environment (XSEDE) for optimal compatibility with XSEDE digital services.
Currently, versions of the XNIT repository are available for x86_64 systems running CentOS 6 or 7. For a list of packages included in each version, see the following README files:
To manually configure
yum to use the XNIT as the default repository:
- On the command line, enter:
yum install yum-plugin-priorities
- Create a
yumconfiguration file (
/etc/yum.repos.d/xsede.repo) with the following lines (depending on your version of CentOS):
- CentOS 6:
[xsede] name=xsede baseurl=http://cb-repo.iu.xsede.org/xsederepo/centos6 enabled=1 gpgcheck=0 priority=98
- CentOS 7:
[xsede] name=xsede baseurl=http://cb-repo.iu.xsede.org/xsederepo/centos7 enabled=1 gpgcheck=0 priority=98
- CentOS 6:
Once the system is configured to use the XNIT repository, use
yum to install packages:
yum install [package_name]
yum install ant
