GridWay is a workload manager that performs job execution management and resource brokering on a grid consisting of distinct computing platforms managed by Globus services. It enables large- scale, reliable, and efficient sharing of computing resources managed by different Local Resource Management systems within a single organization (enterprise grid) or scattered across several administrative domains (partner or supply-chain grid).
CTL is a cross-platform control dispatching tool that makes it easy to automate any kind of distributed systems management or application provisioning task. Rather than writing complex and error-prone scripts that over utilize "for loops", CTL handles the network dispatching for you and allows you to focus on the actual management tasks you need to accomplish. In addition to being a dispatching tool, CTL comes with pre-built cross-platform utilities so you don't have to script actions like file distribution or process and port checking. You can also write your own custom utilities and share them with others in your organization. Custom utilities are defined in XML, and your scripting can be done in multiple scripting languages (Perl, Python, etc.), *nix shell, Windows batch, and/or Ant.
GridShib is a glue layer that transparently binds a grid service provider such as the Globus Toolkit to a role-based authentication and access control system such as Shibboleth, so as to provide fine-grained access controls to members of virtual and physical organizations within a grid without having to distribute and synchronize information about individual users between those organizations.
The gLite distribution is an integrated set of components designed to enable resource sharing. In other words, this is middleware for building a grid. The gLite middleware is produced by the EGEE project. The distribution model is to construct different services ("node-types") from these components and then ensure easy installation and configuration on the chosen platforms.
vzhaipd (scoyo's Virtuozzo/OpenVZ HA IP Daemon) is a set of mount/umount Container scripts for Parallels Virtuozzo or OpenVZ that will make sure a HA IP is always present on one of two or more Containers. You can think of it as the poor man's VRRP for Virtuozzo and OpenVZ Containers. Use it for general service availability, software load-balancer failover, etc.
