UNIX at SLAC

SLAC 21 May 1999
Highlighted Home Detailed Home

Support for UNIX at SLAC consists of fully-supported central services for user authentication, file servers, mail, news, name, time, and print services. A number of servers provide interactive login service for general computing use. Most desktop UNIX systems are supported as dataless clients of the central services; support beyond that level is the responsibility of the individual groups. A compute farm is provided for all users to provide high-performance computing and bulk tape and disk data storage.

Where to go for Assistance

* Local Experts
The first thing you should do is to seek out knowledgeable people in your group. Often, people working on similar tasks can give you the most meaningful help. This should especially be your first line of inquiry for usage and "how-to" questions.
* Newsgroups
Newsgroups can often be a fertile source of answers to questions. There are SLAC, Stanford, HEP, and worldwide newsgroups on a variety of topics. See below for a partial list of relevant ones for UNIX.
* Send email to servdesk@slac.stanford.edu
Questions about how to use the SLAC system, or trouble reports about failing hardware, networks, or system software can be emailed this address or called in to (650) 926-HELP. The phone number includes a paging system for off-hours reporting of critical problems.
* Send email to unix-admin@slac.stanford.edu
Send mail for support of the UNIX environment to this address with full details.

High Performance Computing

* SLAC UNIX Compute Farm
Here is information about SLAC's UNIX workstation clusters for high performance computing.

Acquiring a Desktop System

* Node Name Conventions
Each system on the SLAC network must have a name. Most groups have adopted conventions for workstation names. Consult with members of your group to select a name in accordance with your group conventions.
* IP and Node Name Form*
Fill out this form to have an IP address and node name assigned to your workstation, X-Terminal, Mac or PC. Please do this ten days before your new desktop machine is scheduled to arrive at SLAC.
* Request OS Installation and Tailoring
For supported workstations, the level of Operating System in use at SLAC may need to be installed on your workstation, and local software customizations applied. Click on this link to send mail to SCS requesting installation. Please give us one week notice before the machine arrives. Time for installation will vary depending on overall priorities of staff workload and available staff time.
