This course will cover basic Unix and Windows NT -- the goal of this class is to make you comfortable using computers in a heterogeneous networked environment. No prior experience with Unix/NT is expected.

Computing Resources on Campus

The following computer systems are available to all students, faculty, and staff:

"U Dot" Cluster The u.arizona.edu cluster provides UA affiliates with UNIX accounts. To obtain a u.arizona.edu account, telnet to
and follow the instructions. Once your account has been activated, you can access it via telnet/rlogin at
CCIT Labs CCIT maintains a number of open access labs around campus. Some of these labs contain Windows and/or Mac PCs; others are populated with X-terminals. See the CCIT site list for locations, descriptions, and hours.
Math Lab The Mathematics department has an open access Windows NT lab located in M-226. This room is accessible via the stairs/elevator on the south side of the building or from the main stairwell in the center of the building. It is not directly accessible via the main building elevator. This lab is open from 9AM-6PM Mon-Fri.

Mini Assignment #1

Obtain an account on the u.arizona.edu system. You will use this account to complete the first "real" homework assignment. If you do not currently have a UA or ISP account, use the Math NT lab or one of the CCIT labs to telnet to account.arizona.edu. You will need your full name, date of birth, SSN, and (if you are a student) PIN.

Note:  If you already have a u.arizona.edu account, please see Prof. Restrepo or myself after class, as we will need to arrange for you to get a different account for the first homework assignment. You can use any account available for all other course assignments.

If you have never used telnet, here is (more or less) how it goes in the Math NT lab:

The CCIT lab assistants can tell you what to do in the CCIT labs. CCIT also has a "help desk" phone number at 621-HELP. Questions regarding CCIT systems/labs should be directed to this number.


Visiting Faculty, retirees supporting UA projects,
and certain others with special UA affiliation
should contact the Customer Accounts office for
information on creating an account. 

Customer Accounts Office: 
     Location: Computer Center RM 204 
     Office hours: 9am - 4pm, Monday through Friday 
     Phone: 621-2985 

Please bring UA ID or other picture ID if you
visit the office.

The "account" web page states that

It will take about 5 minutes to complete the
program. New accounts and password changes will
be processed within 1 hour.

Course Resources

Prof. Restrepo's Math 481/581 web page, http://www.math.arizona.edu/~restrepo/481/sci_comp.html will contain pointers to various course related information.

One of the primary resources for the course is the scicomp mailing list. Messages sent to the list will be distributed to all students in the class -- think of it as a forum for things pertaining to the course. In addition, copies of all messages sent to the list will be stored in a searchable, WWW accessible archive. We'll cover the list in more detail on Wednesday.

To subscribe to the mailing list, send email to majordomo@majordomo.math.arizona.edu . The subject of the message is unimportant. The body of the message should contain the single line

			subscribe scicomp
To post a message to all list subscribers, send email to scicomp@majordomo.math.arizona.edu . The subject and message body can be anything you like -- it's just like sending regular email, except that everyone in the course will receive the message.

All messages sent to the scicomp list are also archived in a searchable web-based archive. To access these HTML archives, point your browser at http://majordomo.math.arizona.edu/scicomp .

There will be a weekly office hour on Wednesday from 12:00 to 1:00 in Mathematics Room 707.

Finally, the Internet can be considered a course resource: there are lots of online tutorials/documentation/what-have-you available on the 'net.
