Scalable, distributed monitoring system for high-performance computing
Ganglia is a scalable distributed monitoring system for high-performance computing systems such as clusters and Grids. It is based on a hierarchical design targeted at federations of clusters. Supports clusters up to 2000 nodes in size.
Containment Domains are a framework for computational resiliency
CDs can be thought of as a mechanism to support fine-grained, hierarchical, application-directed, uncoordinated checkpoint and restore. Containment Domains (CDs) were created to allow an application to recover in the face of various types of component failures, including hard (e.g. persistent) and soft (e.g. transient) hardware failures, transient software failures, and complete node failures.
metahelper is a utility which makes creating and maintaining upgradeable, removable, and verifiable configuration "metapackages" easy. A metapackage works with files owned by other packages to customize and configure them specifically for your environmen
Xen is a virtual machine monitor for x86 that supports execution of multiple guest operating systems with unprecedented levels of performance and resource isolation. Linux 2.4, 2.6 and NetBSD 2.0 ports are available. FreeBSD, Plan 9 ports on the way.
