SUN Microsystems 420R (WILLOW)
The UM Research Server is provided and supported by the Ole Miss Office of
Information Technology, for the research and instructional use of all UM
faculty and students. Traditionally, our heaviest users have been UM
professors doing specific research requiring brief but intense periods of
statistical number crunching, using applications such as SAS, SPSS,
IMSL, Lisrel, and Limdep.
PVWave is also installed on willow.
However, plenty of cycles are left over during research lulls, so that
willow has also be used to great effect as an instructional platform for
introductory classes in Fortran and C/C++, an exercise
platform for advanced classes in Math/Business/Education/Psychology
Statistics, an application development platform for seminars in
is also an ideal platform for self-directed learners of Unix and Linux, or any of
the technologies and packages hosted here.
We encourage faculty and students alike to creatively employ the UM
Research Server in meeting your particular learning needs, and look forward
to hearing how we can assist you in getting started. Individual accounts
are available from the IT Helpdesk
in Powers Hall, while class accounts may be requested by emailing an
electronic class roll to email@example.com.
As a general rule, willow accounts are restricted to University
of Mississippi faculty and
students only. Also, classes and research requiring extraordinary support and
resources should be negotiated at least a semester prior to ensure the
platform is ready when you are.
The Sun Microsystems 420R workstation is equipped with four UltraSparcII processing units (CPUs) and 4096 megabyte of memory.
The CPU clock speed is 450 MHz. The word size is 64 bits.
The Sun Microsystems 420R runs the Solaris 9 operating system.
Solaris is a UNIX-derived operating system supported by Sun Microsystems.
Available applications include SAS, SPSS
6.1.3, IMSL, Lisrel, Limdep
a 2.95.2< gcc>, GNU Compilers (g77, gcc) , C/C++,and Forte for Fortran(Sun's
Fortran 90 compiler).
Each user has 40MB quota on home directories and 2GB quota on /ptmp.
Temporary space is available on /temp, which is generally purged less often than /tmp.
For security purposes, telnet, rsh, and ftp have
been permanently disabled on willow. Users will need to login or transfer
files using secure shell, which UM faculty and students may download from the
UM IT Helpdesk.
A PC-based X Windows emulator, XWin32, is also available for download from
the helpdesk, for use on the UM campus. See the UM web pages on ssh
for specific installation and configuration instructions for using those
packages to connect to willow.
Off campus users may need to connect using willow's IP address
(18.104.22.168), rather than its domain name (willow.olemiss.edu) if having
difficulty making a connection.
Documentation is available on-line in the form of man pages.
The standard UNIX man command gives in-depth information concerning virtually all Solaris commands
and utilities. The Solaris online reference manual on Sun Microsystems website also has detailed
information concerning all Solaris commands, system calls and utilities .
Accounts are available for UM students, faculty, and staff, for research or instructional use.
To apply for an account, please visit the helpdesk in Weir Hall and bring your Olemiss ID.
Class accounts expire and are removed after the semester for which they were
issued. Passwords expire every three months, and may be reset online at the IT Self Service website
