Last updated: 09/29/2004
Introduction
This document provides an overview of the computing resources
available in the Stat-OR department. More comprehensive documentation
is already available at this
page, however it needs to be updated. We complement the current
documentation with up-to-date information and discuss the current
status of the computing facilities in our department.
Contents
Hardware
Servers mantained by the High
Performance Computing group:
- StatApps (statapps.unc.edu), the statistical applications
server of UNC, a domain within a Sun E15K server with 20 processors
and 40 GB of memory. Note that statapps.unc.edu is an alias for
sunny.unc.edu. See StatApps documentation at www.unc.edu/atn/statistical/
- Baobab (baobab.unc.edu), the ITS Linux Beowulf cluster for
scientific computing. Currently configured with 352 CPUs! More
details at this
page.
Sun machines in the department (maintained by OASIS):
- savage (savage.stat.unc.edu), a Sun-Blade-1000 with sparcv9
processor at 750MHz, and 512MB of memory.
- seymour (seymour.or.unc.edu), an Ultra-80 with dual
processors sparcv9, each at 450MHz, and 1024MB of memory.
- tucker (tucker.or.unc.edu), an Ultra-80 with dual
processors sparcv9, each at 450MHz, and 1024MB of memory.
Debian GNU/Linux machines in the department (mantained
by COMPUTER COORDINATOR, currently Brian Lopes):
- bayes (bayes.stat.unc.edu), an Intel P4 at 2.8GHz, and 1G
of memory.
- bose (bose.stat.unc.edu), an Intel P4 at 2.8GHz, and 1G
of memory.
- maxwell (maxwell.stat.unc.edu), an Intel P3 at 550MHz,
and 256MB of memory
Setting Up Accounts
The following is information on how to set up accounts in each of
the Unix servers. It is assumed you already have an ONYEN.
- StatApps, Baobab:
- To subscribe to these services, go to
https://onyen.unc.edu.
Scroll down to the section ``Other Services''. Click on the button
``Subscribe to Services''. Enter your ONYEN and password and then
subscribe to the services you need.
- savage, seymour, tucker:
- Request access to these servers at http://oasis.unc.edu/remedy
(you will be asked for your ONYEN and password).
- bayes, bose, maxwell:
- Send email to COMPUTER COORDINATOR.
Logging On
You must connect to the Unix servers using the secure shell (SSH)
protocol. If you use SecureCRT make sure to specify SSH2 as the
protocol in the "Session Options Window". More details at
http://help.unc.edu/?id=4182
The AFS File Storage System
"AFS is a file system used by UNC to provide personal and group disk
storage to anyone with an Onyen. Graduate students, faculty and staff
get 250MB of disk space." More details at
http://help.unc.edu/?id=142.
Note: Save all of your work in your AFS space! Why?
- You can access your AFS space from anywhere
- Files stored in your AFS space are backed up nightly
- It is not safe to store files in the local hard drives of the
computer labs: OASIS may clean the local hard drives.
Accessing Your AFS Space
- PCs: Your AFS space is typically mapped to the
H:
drive. The university network is typically mapped to the
J: drive. If you want to access AFS from your home
computer you need to install the AFS Client Software (OpenAFS 1.2.x)
at https://shareware.unc.edu/software.html.
- Unix: Your AFS space is your home directory, you can
also access it as
/afs/isis.unc.edu/home/o/n/onyen
- Debian/GNU Linux: Your AFS space is linked through
/home/username/afs/.
Software
Email
The email server of UNC is isis.unc.edu. You can access your
email with several email clients, such as:
- pine:
- pine is the safest (low risk of getting a virus) and the fastest
(text-based). To use pine, login to isis.unc.edu. If you have the
menu enabled, choose option 2. If you do not have the menu enabled,
just type
pine at the prompt. For more information see
http://help.unc.edu/?id=98
- Microsoft Outlook, Mozilla Mail, Mulberry:
- Documentation for configuring these email clients is available at
http://help.unc.edu/?id=760
- Webmail:
- See http://help.unc.edu/?id=89.
Remember that:
UNC Webmail is designed as a supplement to, and not a
replacement for, your desktop email client (such as Mulberry,
Netscape Messenger, Outlook, etc.). Webmail should be used in
situations in which you don't have access to your usual desktop
email programwhen traveling or using computer labs, for
example.
Asking for Help
- Ask the person next to you or next door.
- Search help.unc.edu
- For software requests, hardware problems, and any problem related
to the CCI machines, make a service request at oasis.unc.edu
- For questions related to the Debian/GNU Linux machines, send email
to <stat-linux@listserv.unc.edu>. To subscribe to this list
send subscribe stat-linux as the body of your email message
to listserv@unc.edu, leaving the Subject: field blank.
