OpenHPC: Community building blocks for HPC systems. (v1.3)


This stack provides a variety of common, pre-built ingredients required to deploy and manage an HPC Linux cluster including provisioning tools, resource management, I/O clients, runtimes, development tools, and a variety of scientific libraries.

The compatible OS version(s) for this release and the total number of pre-packaged RPMs available per architecture type are summarized as follows:

Base OS x86_64 aarch64 noarch
CentOS 7.3 301 193 43
SLES 12 SP2 306 198 43

A detailed list of all available components is available in the "Package Manifest" appendix located in each of the companion install guide documents, and a list of updated packages can be found in the release notes.

** Important note for those upgrading from versions prior to 1.3

There are significant changes included in the warewulf-httpd.conf file that ships with the warewulf-provision-server-ohpc package. If upgrading from a previously installed version, the updated config file will be saved as /etc/httpd/conf.d/warewulf-httpd.conf.rpmnew locally. You will need to copy this new version to the production file and restart the web server to ensure correct provisioning behavior. As an example for CentOS:

[sms]# cp /etc/httpd/conf.d/warewulf-httpd.conf.rpmnew /etc/httpd/conf.d/warewulf-httpd.conf
[sms]# systemctl restart httpd

Getting started

OpenHPC provides pre-built binaries via repositories for use with standard Linux package manager tools (e.g. yum or zypper). Package repositories are housed at To get started, you can enable an OpenHPC repository locally through installation of an ohpc-release RPM which includes gpg keys for package signing and defines the URL locations for [base] and [update] package repositories. Copies of the ohpc-release package are provided below for convenience. Installtion guides taylored for each supported resource manager are also available below or in the downloads section of the latest release.
