Welcome to the UW Milwaukee pkgsrc repository.
These packages are provided as a service to the scientific computing community.
The vast majority of HPC clusters run Redhat Enterprise Linux (RHEL) or derivatives such as CentOS and Scientific Linux. These operating systems are favored for their reliability and support for running commercial software.
However, RHEL-based systems present a challenge for running the latest open source software due to their use of older compilers and libraries than those found on more cutting edge operating systems such as Debian, FreeBSD, or OS X.
The pkgsrc cross-platform package manager offers a simple solution, allowing users to easily install a self-contained set of modern packages, independent of older Yum packages.
We generate binary packages for each quarterly pkgsrc snapshot with an installation prefix of /sharedapps/pkg-[year]Q[quarter], e.g. /sharedapps/pkg-2017Q1, /sharedapps/pkg-2017Q2, etc. This allows older software to remain in-place for the duration of long-term studies, while newer software is installed under a separate prefix.
Detailed information on using these packages is available at http://uwm.edu/hpc/software-management/.
