Environment

To access the LIONS HPC environment, login to sol-login (sol-login.lions.odu.edu). Most other LIONS clients and all hosts that are not LIONS clients are insufficient. Note that login to sol-login requires remote access (and of course, a LIONS account).

Important!Login is only the first step. In general, sol-login hosts are not for running programs that require a lot of resources (e.g., memory, CPU time, run time, etc.). Know the hardware configurations of the three compute servers int the LIONS cluster.

• Helios - Sun Enterprise 10000 (Starfire)
• Norfolk - Sun Enterprise 3500
• Hydra - Sun Enterprise 2900

Understand load management. After login, access to all LIONS HPC resources is managed and controlled by the Sun Grid Engine(SGE) by SUN.

• SGE-Sun Grid Engine

SGE runs with specific configurations on LIONS to best suit the university academic computing needs. Familiarize with the queue configuration of SGE on LIONS and learn further with the short tutorial.

-A short Tutorial

Be aware that components of the following software packages affect what you do, and how you are able or allowed to do what you want to do (check LIONS Docs and Vendor Docs)

• Solaris by Sun Microsystems
• Krb/AFS

Finally, LIONS HPC hardware information may be useful (and sometimes essential if you write your own programs).
