What to Install?

Major Packages

The VDT is a collection of several software packages; most of these packages provide both client and server components. Many users install the VDT for a specific reason and never make use of the other components. For this reason we've designed several task-specific subsets of the VDT. If you're concerned about installation time, disk space or just installing unnecessary software you can choose the package that works best for you.

VDT
This package will give you a complete VDT install. You can see the full list of software on the components page.
VDT-Client
This package will only install the client side software of the VDT packages. If you want to submit jobs to remote grid sites this is the package for you.
VDT-Gatekeeper
VDT-Gatekeeper includes all the software you'd want for setting up your own grid site. If installed as root this package will configure the gatekeeper for you as well.
VDT-SE-DRM
VDT-SE-DRM includes software for a storage element based on DRM. This includes a GridFTP server and some utilities.
Globus-Server
Just enough setup to have all the Globus servers (gatekeeper, gridftp and MDS)
Globus-Client
Just enough setup to have all the Globus clients such as globus-job-run, grid-info-search, and globus-url-copy.
