This document has moved to https://kb.wisc.edu/math/internal/120899
 
The Wisconsin Undergraduate Research Cluster is a high-performance parallel computing cluster for use by undergraduates for research.
It consists of a cluster of computers on a local area network with identical software allowing processing to be shared among them.
This is known as a [https://en.wikipedia.org/wiki/Beowulf_cluster beowulf cluster].
 
===Operating System===
The operating system on the WURC is currently [http://releases.ubuntu.com/19.10/ Ubuntu 19.10],  Eoan Ermine.
 
===Available Software===
The following is a list of some of the major commercial and open-source software packages and tools available on the WURC.
This list is necessarily incomplete as the WURC has hundreds of Ubuntu packages installed.
When in doubt, the user is encouraged to simply try a command to see if it is already installed.
To request additional software, please contact your instructor.
 
====Compilers and Interpreters====
* Intel C++
* Intel Fortran
* g++
* gfortran
* python (2.7 and 3)
* perl
 
====Mathematical Packages====
* Bertini2
* Gap
* Macaulay2
* Magma
* Maple
* Mathematica
* Matlab
* Octave
* Sage
 
===Connecting===
To connect to the WURC, a user must have the following:
#A valid University Of Wisconsin-Madison netid and password
# A network connection on a University Of Wisconsin-Madison network (including [https://kb.wisc.edu/page.php?id=25020 Eduroam] and  [https://it.wisc.edu/services/wiscvpn/ WiscVPN])
 
====Connecting With ssh====
Secure Shell (ssh) is a cryptographic network protocol for secure remote login and command execution.
Implementations of clients for ssh are available in Windows, Macintosh OSX, and Linux.
 
* Windows
 
Windows 10 has a built-in, optional  ssh client. To install it, do the following:
# Click Settings or press Windows+i to open the Settings app.
# Click 'Apps'
# Select 'Manage optional features'
# Click the 'Add a Feature' button.
# From the list of features, select 'Openssh Client' and click the Install button.
 
Note that the Openssh Client will not appear on the list if it is already installed.
Once the openssh client is installed, you can open a command window and simply type, "ssh <netid>@wurc.math.wisc.edu".
The first time you connect, you will be asked to accept the server key. Type yes to accept the key. This message will not appear the next time you connect from the same computer. If it does, consult your instructor.
You will then be prompted to enter your netid password.
 
The University of Wisconsin-Madison provides no-charge software through our [https://software.wisc.edu/cgi-bin/ssl/csl.cgi Campus Software Library].
Among the offerings are SecureCRT, a secure login client, and SecureFX, a secure file transfer client.
These programs provide a more feature-rich environment than the built-in Windows client.
To use SecureCRT and SecureFX, log into the Campus Software Library with your netid and password and follow the instructions for installing SecureCRT and SecureFX.
Questions on installing SecureCRT and SecureFX should be directed to the DoIT Help Desk.
 
Once you have SecureCRT installed, you can connect to the WURC by clicking on quick connect and entering wurc.math.wisc.edu as the host name and your netid as the user name.
Change the authentication to password.
Do not change any other settings.
Enter your netid password when prompted.
 
* Macintosh OSX:
 
Macintosh OSX has built-in ssh and sftp clients. To use these tools, do the following:
# Switch to a Finder window and open the Utilities folder. The shortcut key to open the Utilities folder is Command+Shift+u.
# Click on the Terminal app.
# In the terminal window, type "ssh <netid>@wurc.math.wisc.edu".
# The first time you connect, you will be prompted to accept the server key. Type "yes" to accept the key.
# You will be prompted to enter a password. Enter your netid password.
 
The University of Wisconsin-Madison [https://software.wisc.edu/cgi-bin/ssl/csl.cgi Campus Software Library] has versions of SecureCRT and SecureFX for Mac OSX
Questions on installing SecureCRT and SecureFX should be directed to the DoIT Help Desk.
 
Once you have SecureCRT installed, you can connect to the WURC by clicking on quick connect and entering wurc.math.wisc.edu as the host name and your netid as the user name.
Change the authentication to password.
Do not change any other settings.
Enter your netid password when prompted.
 
* Linux:
 
Linux has built-in ssh and sftp clients.
Most linux distrabutions will install the openssh client by default.
If ssh and sftp are not installed on your Linux system, you can install them by doing the following:
* Red Hat: sudo yum -y install openssh-client
* Debian and Ubuntu: sudo apt-get -y install openssh-client
 
To connect to the WURC from a Linux computer using ssh, do the following:
# Open a terminal window by pressing Alt+Super+t
# Type, "ssh &ltnetid&lt>@wurc.math.wisc.edu"
# The first time you connect, you will be prompted to accept the server key. Type "yes" to accept the key.
# You will then be prompted for a password. Enter your UW netid password.
