Intel Computer Systems Cluster (the "fish machines")
Intel has donated 24
Pentium III Xeon servers to CMU for systems courses. The systems,
which run the Red Hat 6.2 distribution of Linux (version 2.2.16), are
rack-mounted in the Wean Hall 3rd floor machine room, and are
administered by the CS facilities group. They are rebooted every
morning at 7am.

Frequently asked questions
Q: How do I get an account?
A: Accounts will be created for you automatically.
Q: Are the accounts ready yet?
A: YES! (as of 2pm, Thur, Aug 30, 2001).
Q: What do I need to do before logging in for the very
first time?
A: From your Andrew home directory on one of the Andrew
Unix cluster machines (linux.andrew, etc.), run the following
one-time checkin script:
/afs/cs/academic/class/15213-f01/bin/checkin
Q: What does the checkin script do?
A: It creates two subdirectories in your Andrew home
directory: "15-213" and "213hw".
- The "15-213" directory contains
the .klogin and .login files that will allow you to login from
the fish machines. DO NOT DELETE ANYTHING IN THIS SUBDIRECTORY.
- The "213hw" directory contains secure subdirectories for each of
your seven labs, with the permissions set so that only you can
read the contents.
Remember, you only need to run the checkin script once, before your
very first login to the fish machines.
Q: How do I log into one of these machines once I've run the checkin script?
A: If your Andrew login is bovik and you want to login
to machine FISH, then login as follows:
% telnet FISH.cmcl.cs.cmu.edu
Connected to FISH.cmcl.cs.cmu.edu.
Escape character is '^]'.
Red Hat Linux release 6.2 (Zoot)
Kernel 2.2.16 on an i686
login: bovik@andrew.cmu.edu
^^^^^^^^^^^^^^ don't leave this out!
password: [andrew password]
Alternatively, if you use ssh:
% ssh -l bovik@andrew.cmu.edu FISH.cmcl.cs.cmu.edu
bovik@andrew.cmu.edu@FISH's password: [andrew password]
Don't forget to replace "FISH" with a cluster machine name from
the table below.
Q: I did everything you said but I still can't login. Now what?
A: The main reasons students can't login are:
- They somehow delete the .login and .klogin files in their 15-213 directory.
- They change their Andrew password after running the checkin script.
In either case, delete the 15-213 and 213hw directories, rerun the
checkin script, and try again. If you still can't login, contact
your instructors and we'll get you squared away.
Fish machines that are available to students
Intel engineers traditionally use the names
of North American rivers as internal names for their processor
projects. So it seems fitting that we, as denizens of the Intel
cluster, name the machines after freshwater fish of North America.
The machines can be accessed with either ssh or telnet.

About the Intel Cluster
The machines in the Intel Cluster are connected by a Cisco 3524 switch
with 24 full-duplex 100 Mb/s ports and 2 full-duplex 1 Gb/s ports. The
switching fabric has a peak bandwidth of 10.8 Gb/s and a maximum
aggregate forwarding rate (from port to port) of 5.4 Gb/s.
Each node on the cluster runs Red Hat Linux 6.2 (Linux kernel 2.2.16)
and consists of the following hardware:
- 550 MHz Pentium III processor
- 512 KB L2 cache
- 256MB SDRAM memory using 128MB DIMMS
- Ultra2/Wide SCSI bus and controller, EIDE disk controller
- 9.1GB Ultrawide SCSI hard drive
- Fast Ethernet card
- 16-bit Soundblaster Pro compatible sound card
- 1 parallel, 2 USB, 2 serial, and 1 ultra/wide SCSI ports
- 3 external 5.25" peripheral bays, 4 internal 3.5" hard drive bays
- 1 AGP, 3 PCI, 1 shared, 1 RAID slots
- 40x SCSI CD-ROM
- Harmon Kardan HK195 speakers
- Diamond Viper 2 v.770d 32MB graphics card
