After a user account has been approved and created, the requesting user will be sent an email listing the system(s) to which the user requested and been given access. In addition to the system(s) listed in the email, all users also have access to the following general-purpose systems:

home.ccs.ornl.gov
Home is a general purpose system that can be used to log into other OLCF systems that are not directly accessible from outside the OLCF network. For example, running the screen or tmux utility is one common use of Home. Compiling, data transfer, or executing long-running or memory-intensive tasks should never be performed on Home. More information can be found on the The Home Login Host page.

dtn.ccs.ornl.gov
The Data Transfer Nodes are hosts specifically designed to provide optimized data transfer between OLCF systems and systems outside of the OLCF network. More information can be found on the Employing Data Transfer Nodes page.

HPSS
The High Performance Storage System (HPSS) provides tape storage for large amounts of data created on OLCF systems. The HPSS can be accessed from any OLCF system through the hsi utility. More information can be found on the HPSS page.
