What Should You 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. Note that this package does not include Globus web services, but it will in a future version of the VDT. For now, you must install them separately.
Various Globus packages:
Note that these have some overlap. For instance, you'll get grid-proxy-init in any of these packages.
Globus-Server
Just enough setup to have all the pre-web services Globus servers (GRAM (gatekeeper), GridFTP and MDS)
