Neumann
Neumann is a 32 core Opteron (2.4GHz) computer with 128Gb of RAM. It is the main computational machine for our research group. The following is a list of software installed on Neumann, in addition to the software installed through CentOS. To see a list of software installed, type the command 'rpm -qa' at the command prompt. Most common software (C/FORTRAN compilers (GNU/Intel), emacs, vi) is installed through this.
If you need some software, feel free to install it in your home directory. Linux allows you to install software and use it from any directory. If for some reason, software must be installed for everyone, please email the current system admininstrator (address at the bottom of the page).
Neumann is not backed up. Please keep this in mind, and keep your most important data either on CSIL, or on Gauss (if you have an account there). Neumann is meant to be interactive, so we advice you to run large jobs at night, or when there are few other users on neumann.

Timing Information from Neumann
NOTE THAT THESE RESULTS ARE FOR THE OLDER (16 core 2.2 GHz Opteron, 64GB) NEUMANN. These are provided solely as a generic guide.
In view of future research, here are documents that show Neumann's hardware timing information. All the graphs are the result of the output of LLCBench (No version information. Released on 10/17/2006). The final text file is the result of running LMBench (Ver. 3.0-a9) repeatedly on Neumann.

Gauss
Gauss is the machine that hosts the web server, the productivity data database, and the files for the users. The Web page is maintained here, and if you are modifying the page, please read up on Cascading Style Sheets (the page uses these extensively). Also, please ensure that the web pages are standards compliant. Every page has a link at the bottom that can help you verify the standards compliance. It is easier to maintain the pages (and ensure a good viewing experience) by sticking to web standards.
