The cellsdk script
The cellsdk script is used to install, update or uninstall the SDK. This script is a wrapper with most of the work done by YUM-based tools.
Upgrading from RHEL5 Developer to RHEL5 Product
It is possible to "upgrade" the SDK from the RHEL5 Developer to the RHEL5 Product version simply by downloading the ISO image for RHEL5 Product from Passport Advantage® and accepting the license.
Setting up a YUM server for the SDK
This topic is for advanced users who want to set up a local YUM server. A YUM server allows multiple users to access the SDK files without having to download them from the Barcelona Supercomputing Center Web site or use the ISO images. A YUM server is useful if your company has a firewall that prevents direct access to the Internet.
