XSEDE National Integration Toolkit (XNIT)
Suppose you already have a cluster that you are happy with and you want to add too it software tools that will allow users to use open sources software like that on XSEDE, or other particular pieces of software that you think are important, but you don't want to blow up your cluster to add that capability? XNIT is for you. You can add all of the basic software that is in SCBC, as relocatable RPMs (Resource Package Manger), via a YUM repo . (YUM Stands for Yellowdog Updater, Modified).
