Obtaining Additional Computer Accounts

  1. Go to the Access Management Page and click on the Create Additional Accounts link.
  2. You will be prompted to enter your IU username and passphrase and only then will you be taken to the next page.
  3. Select an account on Karst, Big Red 2, or Mason (using the radio buttons).
  4. Click on the Create Account button at the bottom of the page.

You will be contacted via e-mail when the account has been created. This can usually be accomplished the same day you apply to create the account. You may also find it useful to request a Scholarly Data Archive (SDA) account, and accounts on Mason and Big Red II if you plan to do extensive image analysis of data collected using the EMC's electron microscopes. These are other options under the create more accounts link but must be done separately from the computer account request.

Requesting an account should be done at least a day before attempting to access data. Even if you do not plan to do any image processing using Karst, you will need to log onto the system once to prevent trouble accessing your data in the future.

You will need to do several things after logging onto the computer clusters for the first time. Both how to log onto Karst and what you need to do the first time are described elsewhere. Especially if you are unfamiliar with working on a computer that is command line (terminal window) driven, you should work with the staff to do everything necessary.

We have posted a short linux tutorial that introduces some of the key concepts that operate inside linux machines and many of the basic commands on the clusters that will be useful to examine and manipulate data collected by the JEOL JEM 3200FS. In addition, a good overview of Karst itself can be found here.

In addition to this basic understanding of how to work in a command line driven environment, we are creating a series of graphical user interfaces (GUI's) that will interact with the queue manager for Karst and which make submitting jobs to the cluster much easier. This on-going GUI project is driven mostly by need and a reasonably up-to-date list of the programs that can be submitted to the queue manager using these custom built GUI's is available here. Please contact David Morgan about other programs that you would like to submit to the cluster via these custom-built GUI's.
