High Performance Computing at UCI

February 3, 1997 by Dana Roode

On December 19th, NACS met with a cross-section of campus faculty “consumers” of High Performance Computing (HPC) to discuss the current state of HPC at UCI. The group included approximately 25 researchers from fields that have historically dominated use of HPC – engineering, chemistry, physics and biological sciences.

HPC refers to significantly faster “number crunching” power than desktop computers are capable of. Contemporary HPC machines can perform hundreds of millions of “flops” (Floating Point Operations Per Second); a typical 200 MHz Pentium PC peaks at about 70 Mflops.

Currently, UCI supports HPC in various ways – by purchasing time at the San Diego Supercomputer Center (SDSC) on the Cray C98 vector machine (7,600 Mflops) and on the Cray T3E massively parallel processor (MPP). NACS also provides access to UCI’s own aging HPC system – a 4 vector CPU Convex C3840 (480 Mflops).

The participants at the December meeting engaged in a lively give-and-take discussion. All agreed upon the importance of the UCI network and of the support given to the faculty and their research group by NACS’ Departmental and Distributed Computing Support group (DDCS). There were differences of opinion about the role of NACS in providing other HPC resources to the UCI community, with some speakers advocating the need for a centrally-managed facility, such as a workstation cluster, or central multi-processor shared memory machine. Others felt that the days of “big-iron” had ended. UCI is not unique in this respect – discussions of this type are going on at many other universities.

If you are interested in participating in discussions about HPC and computational science at UCI, please let us know by sending e-mail to “AAG@UCI.EDU” . For more information on HPC at UCI, please take a look at the following Web page:

Delivering Your @UCI.EDU Electronic Mail

February 3, 1997 by Dana Roode

UCI’s Mail Transport Agents (MTAs) are the computers responsible for delivering electronic mail addressed to your “@UCI.EDU” e-mail address which is published in the UCI Phone book and elsewhere. NACS currently provides 4 MTA machines that are constantly on-the-job. Each day the MTA systems route an average of 40,000 messages. These machines also process e-mail sent from certain on-campus mail gateways to other destinations on and off-campus.

The MTA systems use the e-mail delivery information (called the”delivery point”) contained in UCI’s online directory database (Ph/Qi) to know where to deliver electronic mail. To be sure your @UCI.EDU mail is being delivered to your preferred electronic address, use the online directory update form:

http://www.uci.edu/cgi-bin/phupdate

The field labeled “email” is the delivery point, which should be your local computer ID, an @ sign, and the name of the mail system from which you read and process your mail.

Electronic Eduational Environment (EEE) – Fall 1996

January 14, 1997 by Dana Roode

EEE enjoyed a successful Fall, 1996 quarter, and we would like to share with you some interesting statistics. You may find detailed information in the Web at: http://eee.uci.edu/doc/stats/

Included at this location is information about EEE Course Web Pages, Course Mailing Lists, and Course Newsgroups which show access and campus participation last quarter.

The EEE Web site logged over 640,000 visits during Fall quarter. The site maintains links to educational resources on campus, including Registrar services for both faculty and students, UCI Libraries resources, Clone Factory Web printing, archives of course e-mail announcements, and course Web pages (electronic syllabi, assignments, references, exam grades, etc.). The Fall 1996 EEE Web linked to 85 UCI course Web areas (http://eee.uci.edu/96f/) with a total enrollment of 8,270.

EEE is the central reference point for UCI course Web resources — to request a link be added for a class Web resource not on the EEE server, see the request form located at: http://eee.uci.edu/forms/course.html

Instructors interested in requesting a course home page on the EEE server may fill out the application form located at:http://eee.uci.edu/forms/application.html

Automatically generated EEE Course Mailing Lists and Newsgroups are an easy and fast way to communicate with all students enrolled in a class. During the fall, 274 Mailing Lists and 12 Newsgroups were created; 290,000 e-mail messages and 10,300 Newsgroup messages were distributed to 14,600 enrolled students. To access the archive of these mailing lists, see http://eee.uci.edu/96f/w3m3/.

NACS continues to provide support for faculty, instructors, and teaching assistants as well as building educational tools and maintaining the EEE infrastructure. Please send any questions or comments to EEE@UCI.EDU.

NACS Operations, We’re Always Ready When You Are!

January 14, 1997 by Dana Roode

It’s 3am and somehow you just can’t sleep, what to do?

 

Well, if the late, late movie does not appeal to you, what about finishing up your computer assignment or making some progress on that Web research you are doing for your next class session? Just do it! You don ‘t need to wait until daybreak, the NACS Operators are ready when you are, keeping UCI’s central computing and communication systems up and running. Other than the Campus police, NACS Operations is the only department on Campus open 24 hours a day, 7 days per week! Operators even carry a portable phone when walking around the labs to ensure they won’t miss your call!

Dialing (949) 824-6065 assures computer users of reaching a real person, not an abstract voice-mail system. Computer operators wear many hats; we sell print-cards and diskettes,

 

we keep the laser printers going, we help students, faculty and staff with their computer questions, we handle after-hour network problems and page technical personnel when needed. We also do mundane (but critical!) things like backing up files for NACS’ DDCS clients while they sleep! 

 

Sometimes we won’t be able to immediately solve your problem, but rest assured, we’ll point you in the right direction, or perhaps, just perhaps, we’ll tell you to go back to sleep and call us in the morning!

The classes are conducted at the Electronic Communication Services office in our conference room. We cover everything from the basics to the creative, providing “hands on” training. You may sign up for a class by calling ECS at 824-5123 or by sending E-mail to Gpbonham@uci.edu.
