Scyld ClusterWare HPC

Scyld ClusterWare™ HPC is an HPC cluster management solution. It was designed to make the deployment and management of a Linux cluster as easy as the deployment and management of a single system. Scyld ClusterWare HPC makes it possible to leverage the superior price/performance ratio of Linux on commodity hardware without the pain of having to individually manage a multitude of systems. Scyld ClusterWare™ HPC is a fourth generation product architected by the father of Linux clustering Donald Becker.

Scyld ClusterWare Architecture

A Scyld ClusterWare cluster consists of a master node and compute nodes. The master node is the central point of control for the entire cluster. Compute nodes appear as attached processor and memory resources. Scyld ClusterWare's architecture is based on three principles:

  • Compute nodes are provisioned through a network boot process from the cluster's master node into local RAM. An Operating System installation to local disk is not required. Libraries and drivers are provided to compute nodes by the master node on-demand. Configuration and version inconsistencies in the cluster are avoided by design.

  • With Scyld ClusterWare HPC compute nodes run a lightweight operating environment. Only one system service, used for communication with the master node, is launched on each compute node. In contrast, compute nodes in most other cluster management architectures run general purpose, workstation oriented operating systems; an approach that introduces unnecessary overhead and security vulnerabilities.

  • Scyld ClusterWare provides a unified process space across all nodes in the cluster. All processes in the cluster are visible and can be directly controlled from the master node. Remote execution services on compute nodes are not required. The Scyld ClusterWare cluster has the look-and-feel of an SMP system.

Scyld ClusterWare is compatible with RedHat Enterprise Linux and has been a component of several Intel® Cluster Ready certified HPC stacks. Scyld ClusterWare is supported on systems with 64-bit processors from AMD® or Intel®.
