Access Information
Who Can Log In?
- Any Auburn University engineering student has access to the HPCC. You will need to send an email request to admin@eng.auburn.edu before being able to log in for the first time.
- Use your Auburn username and password to log in, any additional user id and password is not required
Accessing from a Windows Machine - Configuring SecureCRT
SecureCRT is a terminal based program that allows you to remotely login. You can download it from AU Install.
- Install SecureCRT
- After Launching SecureCRT, go to connect button and click it, then on session Right Click and, go to new session and click on it
- Click Next
- If you are connecting from an Engineering machine then the host name is hpcc.eng.auburn.edu and user id is your Auburn User ID. If you are accessing from off campus, the host name should be gate.eng.auburn.edu. Replace hpcc with gate in the following examples. After connecting to gate, you will be asked for the Engineering hostname, which is hpcc.
- Click Finish
- Click on hpcc.eng.auburn.edu session and click on properties
- Click Remote/X11 and check Forward X11 packets and click Ok
- Click on hpcc.eng.auburn.edu session and hit connect
- Accept & save
- Provide your password and hit ok
- Type "showq" and hit enter, it will show you currently available and used resources..If you see that you are on the head node and Congratulations!!
- To exit from the shell you must type "exit"
Accessing from Windows - X-Win32 Configuration
X-Win32 handles displaying graphics for any remote graphical application. It can be installed from the College of Engineering network and is also available on the Freshman Compute Initiative (FCI) CD.
If you have X-Win32 installed, click on X-Config (not X-win32) to configure X-Win32
- In the session tab, uncheck Last Session Terminate (delete any previous session by Right Clicking on that session)
- Click on the Window tab and click on Multiple Window
- Click on Security tab and click allow all host addresses, click Now click on X-win32 (not X-Config) from program files and you'll see this icon on your toolbar at the right bottom of your machine.
Anytime you invoke an application with Graphical User Interface, you will see a security warning. You will need to check the box Allow This Instance.
Accessing the Cluster from Linux or Mac
If you have Linux or Mac you can just open a terminal and type
ssh -X au_user_id@hpcc.eng.auburn.edu and hit enter
It will ask you for a password and if you provide your au_password, you'll be logged in. You do not need any extra software.
You can copy files from your local linux machine to the remote machine using
scp Desktop/test.m au_user_id@hpcc.eng.auburn.edu:
Copy files from the hpcc machine to your local machine using
scp au_user_id@hpcc.eng.auburn.edu:another.m Desktop/
Creating a .rhosts file
No matter which application you use, you need to create a simple .rhosts file so that the compute notes can communicate.
The .rhosts file will contain five lines:
hpcc
compute-1
compute-2
compute-3
compute-4
You can either edit in vi/gedit editor or download it provided below
Right click on .rhosts and click on save target as, name it as .rosts download it in your H:\ drive
Creating .mpd.conf file
Save and edit .mpd.conf file with your user id like
secretword = your_au_user_id
Make it readable and writable only by you (chmod 600 .mpd.conf)
H: Drive
- Any thing you generate in HPCC, it is generated to your H drive
- You can copy file from you local machine to H drive and you can see it in HPCC
Add RSA Keys
Multinode application usually communicate with every other node which requires rsh/ssh to communicate without password. Therefore in order to add RSA keys permanently, you need to type
ssh compute-1
exit
ssh compute-2
exit
ssh compute-3
exit
ssh compute-4
exit
If it does not ask for password to log-in to any of the compute nodes, you are ready to go!

Application Software
We already have Matlab, Fluent, Ls-dyna, Starccm+, Fortran, C/C++ running on the HPCC.
Matlab/Starccm+ can be run either in Graphical User Interface (GUI) mode or in Batch mode.
For Fluent, Ls-dyna, Fortran, C/C++ job must be running in Batch mode.
