 +====== MN computer systems ======
 +The Manufacturing Networks Group has a number of Linux computer systems that are stacked in 19" rack systems. Hence the name //serack systems//. These computers are configured as separate systems or as a cluster of systems. Separate systems are named //​serack-nn//,​ clusters are named //​secluster-nn//​. (nn is a unique 2-digit identifier number.)
 +
 +In a number of courses and assignments these systems are available to let you use the software tools that were developed to create and run simulations. In most cases, registration through [[http://​oase.tue.nl/​|OASE]] is sufficient to let you use your Windows accountname to log in. Just add the letters tue+ as a prefix to your accountname. (So, s012345 becomes tue+s012345)
 +
 +Accounts that are not related to any specific course also exist (final assignment, bachelor project, etc.). They do not have the tue+ prefix, and should be applied for by your coach/​supervisor. ​
 +
 +If you are outside of the campus network you must setup a VPN (Virtual Private Network) connection first. Once you are on the campus network, the preferred way to connect to the serack systems is through an SSH (Secure Shell) connection.
 +
 +Some [[#Useful tips and tricks]].
 +
 +===== serack-nn.se.wtb.tue.nl =====
 +The range of systems you may be able to access goes from serack-70...serack-77,​ and serack-80 and serack-81. You are free to choose whichever system you like, but it is prudent to take a look at this [[http://​serack-64.se.wtb.tue.nl/​status/​|information page]] that shows you which systems are on line, and how busy each individual system is. You should choose a system with a light load, of course. Although the information page shows all active systems, you may not have access to all; this depends on your access rights.
 +
 +Please note that students with a tue+s123456 account cannot login to serack-75..77,​ 80 and 81. These systems are reserved for staff members and graduate students.
 +
 +You should be aware of some important path settings to our software:
 +  * ''/​opt/​se/​bin''​ is the path to the SE software
 +  * ''/​usr/​selocal/​bin''​ is the path to third party software
 +  * ''/​usr/​tuelocal/''​ is the path to various Matlab and Mathematica releases
 +
 +To make access (and version selection) easier, we have created //​toolselect//​. See [[ToolSelect]] for information to install it, and select versions of software with it.

 +/*
 +===== secluster-nn.se.wtb.tue.nl =====
 +At the moment [[http://​secluster-02.se.wtb.tue.nl/​ganglia/​|secluster-02]] is on line, but not directly available to the general public. It uses the [[http://​www.rocksclusters.org/​wordpress/​|Rocks]] cluster software. If you have to do lots of simulation jobs, and would like to run them on the cluster, please contact your coach/​supervisor. He/she can contact systems management to create a user account on the cluster (see [[how_to_get_a_linux_account|details]]).
 +
 +The [[http://​www.rocksclusters.org/​rocks-documentation/​4.3/​|Rocks User Guide]] ({{:​sesystems:​rocks-usersguide-4.3.pdf|pdf version}}) may help you getting started.
 +
 +A tutorial to help you getting started on the cluster with chi 1.0 is available at [[wiki:​seclusterchi1.0|chi 1.0 on SE cluster]]. An additional example of a python script to run simulations on the cluster is available at [[wiki:​secluster|SE cluster]]. ​
 +*/
 +===== Windows Users =====
 +You will need some additional software before you can set up a connection: (Some packages are licensed, so you may not be able to download.)
 +
 +  * The {{:​sesystems:​vpnclient.zip|Cisco VPN client}} software (6 Mb file), if you are outside the campus network
 +  * The [[http://​w3.tue.nl/​nl/​diensten/​dienst_ict/​services/​services_wins/​campussoftware/​ssh_secure_shell/​|SSH Client software]], for a command shell and secure file copy
 +  * A better editor, like [[http://​www.ultraedit.com|UltraEdit]] (buyware) for editing program files
 +  * A version of [[http://​w3.tue.nl/​nl/​diensten/​dienst_ict/​services/​services_wins/​campussoftware/​open_text_exceed|HCL Exceed]] if you need the X windowing system,
 +  * Or, a version of [[http://​sourceforge.net/​projects/​xming/​files/​latest/​download|XMing]] if you need the X windowing system.
 +
 +
 +===== Useful tips and tricks =====
 +  * [[How to get a Linux account]]
 +  * [[Using the SE racks from Windows using SSH]] Also explains how to use graphical (X11) programs
 +  * [[Using Linux]]
 +  * [[ToolSelect]] How to make the commands to compile and run chi software available in your environment.
 +  * [[Running long computations]]
