Computer Lab and Accounts: CSE 100

Lab Location

Tutors will be holding lab hours for CSE 100 in lab B230, according to the lab schedule posted on the main webpage. This schedule will be updated weekly.

Computer Lab and Accounts

Each student in the course will have an account to use for coursework.

Your account name will either be your UCSD network email account name, or a special course account starting with "cs100f", as in cs100feu. To see which one you should use for the course, use the Account Lookup Tool. If you see a "cs100" account name there, use it; if not, use your UCSD network email account name. If you are using your UCSD network email account, make sure you prep your account by typing cs100f.

Your accounts are hosted on the machine ieng6.ucsd.edu, a load-balanced multiprocessor server running the CentOS Linux operating system. We will use the b>g++ compiler in this environment. These resources are for work related to CSE 100 only. Do not use ieng-250 as it is a 32-bit system.

Access to the server is available via workstations in the instructional labs in the basement of the CSE building, EBU3B, as well as the server, remotely using ssh.

Getting into the labs

Labs are unlocked M-F 7am-10pm and Sat and Sun 7am-7pm. You can get in the lab 24 hours a day 7 days a week using the combination provided for this class. This combination is available using ACS's account lookup tool at http://sdacs.ucsd.edu/~icc/.

Logging on

Move the mouse. The screen should wake up. These workstations are dual boot Windows and Linux machines. If the machine offers you a Windows login, you must reboot into Linux:
- At the Windows login hit "Ctrl-Alt-Del", select Options, Restart, Click OK
- As the machine restarts, you will get a screen where you can choose to boot into Windows or Red Hat Linux. Use the keyboard arrow keys to choose Linux and hit enter.
Now you should have the Linux login splash screen, and a box asking for your username (or login). Type your username (followed by Enter, of course). Don't know your login or password? Get access to a web browser and use the ACS account lookup tool!
When prompted, type in your password.
You will be logged in and brought to a Linux desktop environment. Towards the left of the top menu bar is the Applications menu. Clicking it will pull down a menu with various options.
You can customize the graphical user environment provided for Linux if you want. (For example, any of the icons in the pulldown menus can be dragged to the menu bar to make accessing them quicker.) But for the basic command line interface, just right click on the background and select "Open Terminal" from the menu shown. You can do this multiple times to get multiple Terminal Windows. (When you log in remotely, you will be automatically in a terminal window).

Logging off

Don't forget to log off of your machine when you are leaving it! In the GUI, click on the red hat in the lower left hand corner and select Log Off. Then Click OK in the dialog box that pops up to complete your logout.

You can use your home computer or any other system to experiment with programs for this course. However, your programming assignments will be graded using the g++ compiler (version 4.8.1), on ieng6 only. It is your responsibility to make sure your programming assignment solution works in this environment!
