 === How to connect to MTL ===
-MTL has registered one of York's IP addresses to their system, so we can connect through //"Direct IP."// The IP address registered is indigo.cse.yorku.ca, so to connect to MTL, we need to connect to indigo first. If you're using the computer on campus, open terminal and type **''ssh indigo''** (doesn't need username and password). If you connect from home, use an ssh client to connect to **''indigo.cse.yorku.ca''**, then login with your cse account and password.

 From indigo, we can connect to MTL using this command:
-  ssh -l username 192.55.51.81
+  ssh -l username 207.108.8.131
 The username and password will be provided by email.

+[[http://winscp.net/eng/index.php|WinSCP]] is a very nice freeware SCP/FTP/SFTP package for Windows.  (It also has it's own embedded SSH terminal, but it's not terribly useful.)  With WinSCP, you can connect to MTL from your home computer and drag and drop to upload/download files.
+To connect to MTL with WinSCP, set up a session with MTL's IP as the host, and your MTL username/password.  Then, before you save/connect to the session and close the window, set it up to tunnel through indigo to MTL by clicking the "Tunnel" item in the tree-pane on the left, and checking "Connect through SSH tunnel," entering "indigo.cs.yorku.ca" as host, and your EECS username/password.  After this, you can interact with the file structure on MTL as if it were a part of your local file-system.
 === How to run an experiment ===
+<html>
+<!--
 MTL consist of one login machine, and two experiment machines. To run a program on the experiment machine, we should submit a script to the batch system using this command:
   qsub <script_name>
@@ Line 66: / Line 72: @@
 The latest version of Java is not the default JVM, so we should specify the full path **''/opt/java/latest/bin/java''**. Wall time is the maximum time that your experiment may run. Setting this value can help terminate your job in case it deadlocks or gets into an infinite loop.

+=== Determine some CPU-Specs ===
+Since the job is executed in somewhat like a black-box after assigning it to the queue, one may ask what is the underlying system. The following Java snippets provide some system information: {{:csystem.txt|}}. Another possibility is to use bash commands. The following file shows an example to get detailed cpu information and current cpu clock-frequency: {{:cpu.txt|}}. The current cpu clock-frequency may vary over execution time due to energy-saving features of the cpu. So, one may check the current cpu clock-frequency several times during the experiment.
