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.
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.
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).
