Rocks is a Linux distribution that is open-source and specifically designed for the straightforward creation of computational clusters, grid endpoints, and visualization tiled-display walls, catering to the needs of its users. Since it launched in May 2000, the Rocks development team has consistently aimed to streamline the deployment and management processes of clusters, ensuring they are easy to install, maintain, upgrade, and scale efficiently. The latest iteration, Rocks 7.0, also referred to as Manzanita, is a 64-bit exclusive release built on CentOS 7.4 and includes all updates as of December 1, 2017. This distribution provides a wide array of tools, such as the Message Passing Interface (MPI), which are crucial for transforming multiple computers into a cohesive cluster. Users have the option to personalize their installations by adding extra software packages during the setup phase with the help of specially designed CDs. Furthermore, the recent security issues known as Spectre and Meltdown affect nearly all hardware systems, and to address this, the operating system updates have been implemented to bolster security measures. Consequently, Rocks not only enables the efficient setup of clusters but also guarantees that they are secured and maintained with the most recent updates and patches, ensuring optimal performance and protection for users. Additionally, the community surrounding Rocks continues to grow, providing a valuable resource for users seeking support and sharing best practices for cluster management.
