The following accessible systems provide a variety of services:

Web hosts

Provide a place for researchers (on and off campus) to gather and build virtual communities (e.g., UD’s Sakai@UD portal,,

Code repositories

Such as subversion (svn) let you share and develop code with UD and non-UD collaborators.

File sharing

Provides a common space for storage.

Compute hosts

Let you run specialized software and develop scientific programming codes. These hosts can be connected via ssh tunnels, secured by your home directories’ public/private keys. These trusted links can be extended to other off-campus UNIX systems on which you have a private home directory.

Off-campus access

Facilitated by UD’s network-access services. The license access server lets you use certain licensed software that could otherwise only be used on campus. The Web proxy server allows off-campus access to Web-accessible material, such as online Library databases and journals, whose use is restricted by license. And the VPN server provides a secure connection to private or internal UD resources when you are off campus.

Federated identity management

Provides a network-based mechanism to prove your UD identity to non-UD resource providers. National supercomputing centers, academic research centers, and governmental agencies need to know who you are before providing access to their resources. UD’s identity server and our InCommon membership facilitates this trusted relationship.


An environment scientists and engineers are using to interactively share computing resources, data, and expertise.
