The research librarian is looking into academic market share stats.  Here
are some I found on Lexus-Nexus.

Trends-Operating Systems; Pg. 17,
Al Gillen, an analyst at International Data Corp. who follows the OS market,
says Linux accounted for only 2.8 percent of worldwide paid desktop OS
shipments in 2002. All variations of Windows accounted for 93.8 percent of
worldwide paid shipments.  The key word is paid. Linux backers point out
that the Linux distributed for a fee by vendors such as SuSE Linux is just a
slice--how big is anyone's guess--of the total number of Linux desktops. Sam
Hiser, marketing project leader for OpenOffice.org, which supports the
OpenOffice suite, argues that most users download Linux and OpenOffice free
from one of dozens of Web sites. "Linux being Linux, you can't track
shipments," he asserts. "Many are simply handed across work groups on CDs
that people burn."

And by yearend 2003, according to IDC, Linux will have surpassed Apple's Mac
OS, which has 2.9% of the market, as the second most popular operating

Universities Speed Up Open-Source Plans;
BYLINE: Caron Carlson
In the hopes of gaining more control over their infrastructure, more
university IT administrators are accelerating plans to migrate to
open-source technology in the data center.  George Washington University,
for one, is in the process of removing Microsoft Corp. technology from its
data centers and replacing it with Linux, primarily because of the cost and
burden of security patching, said David Swartz, CIO at GWU, in Washington.
Swartz spoke at a ComNet Conference & Expo panel here last week. "We're
doing this as soon as possible. I want it done in three months, which
translates to about one year," Swartz said. "A lot of my folks would like to
drive more and more toward open source."

Many vendors of science and engineering software have ported their software
to Linux in recent years.  Here are just a few examples:
    * Math: MATLAB (S), Maple V (S),  Mathematica (S), Macsyma, AXIOM,
    * Spatial or Image Data: IDL, ENVI, TNTmips, TNTlite*, PCI Imagehandler*
    * Fortran/C/C++ compilers:  Cygnus, Fujitsu, Absoft, NAG, Portland
    * Lab Automation: National Instruments LabView
    * Document Processing: FrameMaker

The OpenScience project is dedicated to writing and releasing free and Open
Source  scientific software. We are a group of scientists, mathematicians
and engineers who want to encourage a collaborative environment in which
science can be pursued by anyone who is inspired to discover something new

 Linux supercomputing grid unveiled for science use
The National Science Foundation (NSF) yesterday announced a $53 million
project to connect a series of remotely located powerful computers into a
high-speed Linux supercomputer grid that could open vast new opportunities
for scientific and medical breakthroughs. Called the Distributed Terascale
Facility, the project will link powerful servers running Linux into a
high-speed grid that will allow researchers to use all the computing
resources they need, regardless of where the servers are located. At their
disposal will be computing power of huge proportions, with a total of 8.1
TFLOPS and the ability to perform 13.6-trillion calculations per second.

Japanese scientists have built their largest distributed-computing grid yet,
a Linux-based supercluster that performs 11 trillion floating operations per
second, at the National Institute of Advanced Industrial Science and
Technology (AIST)

As Japan's largest public research organization, AIST is charged with the
mission of research and development in industrial science and technology, as
well as undertaking complex geological surveys, setting measurement
standards and developing technological applications for the private sector.
