User Account Request
As of April 2016, the next-generation MCC is now available. Please visit: MonARCH Home for more information, including how to gain access.
The MCC is available to all Monash researchers and research students. To get access to the MCC, please apply via email to:
Remember to include your Monash authcate username, as well as your current status (i.e. PhD Student, postdoc, etc.), departmental affiliation, and the name of your supervisor or research team lead (if applicable). It will also help us if you can briefly describe the type of computational work you wish to conduct on the system, including any software requirements (e.g., packages, compilers, tools, etc.) Please never disclose your authcate password.
Once your user account is active, an email containing brief introduction and some important information about accessing your MCC account will be sent to you. It takes a maximum of two business days to process an account.
Since late March 2016, the MCC has changed its identity management system to align it with e-Solutions best practices. All active users of the MCC will need to login using their Monash Authcate. Changes to the cluster will commence from Wed 30th of March 2016.
In the future, if you need to change your password for the cluster, please visit this page to update your authcate password. https://identity-management.monash.edu/change-password
On msgln6.its.monash.edu.au: the Monash Authcate password is the only one you need to use.
Log-in procedure for the Monash Campus Cluster
Once your account is setup, you will need to login into one of two computers using a program known as ssh.
Login node with accessibility within the Monash network. Access is possible from outside if Monash VPN is used. You can use passphrase-less SSH keys.
This is a virtual machine with four AMD CPU cores and 12 GB RAM.
Note: If you have changed your password after April 1, 2016, you will find that your old password will continue working. Please use the current authcate password to sign into msgln6.its.monash.edu.au.
|This is the preferred login node with public access from outside the Monash network. This is a physical server with 12 Intel CPU cores and 48 GB RAM, ideal for software builds and data transfers. You must use passwords with logging in via SSH/SCP. Use your Authcate username and password to sign in.|
Please use your authcate username for login ID. This login node and the execute nodes mount the same home directory, so your files will be accessible from any node that is part of the Monash Campus Cluster. This login node is accessible (via ssh) from within the Monash network or via VPN connection if connecting from outside.
From this login node, you should be able to:
- submit and manage your jobs with the usual qstat, qsub, qdel commands
- use scp (WinSCP, if on MS Windows) to upload/download your files. [ rsync is best avoided due to high demands to CPU and I/O ]
Compute intensive jobs should not be run on the login nodes. That is what the compute nodes are for!
You will need to use ssh (secure-shell) to login to either headnode. This program encrypts your interactions with the server, and is the only way to login interactively. How to get and use ssh depends upon your desktop operating system.
ssh built into it, so you do not need to install any software.
To login using the authcate jsmith, you would open a terminal window and type:
Enter your Monash password when prompted. Note that if successful, you get a welcome message (Message Of The Day). This often contains useful information, like planned down-times.
In this example, -Y is added so you can use X11, i.e. so that graphic programs can be displayed on your PC. A full list of command line options for ssh can be found by using the Unix 'man' program:
Like Linux, OS/X has
ssh built in.
You access ssh from the terminal program, using the same commands as Linux.
ssh is not native to Windows, but you can download several free versions. Many Monash PCs have a version of ssh installed already on them.
You can download putty from http://www.putty.org/ Once installed you run putty:
Select “Session:” on the left pane. A step-by-step procedure to configure Putty is provided below. The example below uses
msgln4.its.monash.edu but you are welcome to use
If you want to use X11, you must select "Enable X11 forwarding" (found under the SSH->X11 menu) as shown in step 4 above.
A terminal window will open when you hit the "Open Button"
Cywgin creates a Unix-like environment on your PC. Download it from http://www.cygwin.com/.
Run setup.exe and follow all prompts till it shows the "Select Packages" screen. You must select the Net category, and then select
openssl as follows:
When installation is finished, run the Cygwin terminal window. You will find ssh is there and it runs like in the Unix environment
X11 allows GUIs from remote machines to be displayed on your terminal. However you need X11 software installed on your desktop machine. This is default for Linux and Mac users, however PC users need to install it. There are at least two choices:
Some Monash machines have X-Win 32 already installed on them. If not, remember that that it is a commercial package, so please check if you have permission to install it. If so, you can install it using the "Install from Network" link inside Windows Control Panel->Program.
File upload and download
On Windows, you will need WinSCP to transfer files between your local machine and the MCC. It is recommended that you download the “Portable executables” at the link:
On first run, you will need to setup the hostname (under “Host name”) and optionally, put your username on the “User Name” field. It is not recommended that you keep your password stored on this program, for security reasons. When ready, click the “Save” button (see below left). The next time you run winscp, you can now use the stored settings and login to the Monash Sun Grid by clicking on the listed session and click “Login” (see below right). Within this program, you will be able to upload or download files to/from the Monash Campus Cluster.
On the Mac OS/X and Linux, there is a built-in secure copy console command sep. This is used as follows:
The above command recursively copies the files within
data1 (if it is a folder) to the top level (
$HOME) directory on your MCC account. The command below downloads all files within the
folder1 into the local destination folder "
