Tcl/Tk would be easier:
set stdout [exec fortranprogram option option ... ]
*or*
set stdoutfp [open [list |fortranprogram option option ...] r]
gets $stdoutfp line
...
close $stdoutfp
People *have* called Fortran subroutines from Tcl/Tk (do a deja search
in comp.lang.tcl). It is also possible to call Fortran subroutines
from a C or C++ main program. QT is a C++ class library / widget set /
X11 Toolkit.
Fortran has always been best for massive number crunching applications.
It is also NOT a dead language. Compaq is in the process of porting
the DEC 'High Performance Fortran (F90)' compiler to Linux. Fortran,
as a language, is well suited to being compiled for SMP processing --
the *compiler* handles all of the SMP optimization and data
organization -- no need to put in specific calls to manage
multi-processing games (i.e. threads and stuff). Mostly *because*
Fortran is simple.
I've written a couple of Tcl/Tk front-ends for Fortran programs. In
the case of these programs, the Fortran program took a parameter list
via a Namelist file. I wrote a Tcl/Tk that built/edited this parameter
file, forked the Fortran program, and captured the output stream to a
text window. The program main I/O is binary image data, that the
Tcl/Tk code made no use of -- the parameters with other stuff --
angles, distances, scale factors, filenames, processing modes, etc.
Tcl/Tk is in fact great for this. If you want, I can talk to the
professor I wrote this program for and see if I can send you the Tcl/Tk
script. Let me know via E-Mail.

If you select a custom install, you'll be able to pick and choose
which packages you install onto your PC.
At a minimum, you'll need X and a window manager.
By the way, all of the documentation that I've seen for installing
Oracle on linux suggested using KDE as the desktop environment.

I noticed from storagereview.com that there is at times signficant
differences
in performance of a hard drive between Win9x and WinNT. I will
be purchasing a couple of hard drives in the next couple of months,
which
will go into a Linux box. I was wondering if there are any comparisons
of disk performance under Linux that I might go to.
Thanks,

Subject: Cannot FTP on new RH Install
Date: Tue, 21 Mar 2000 20:23:20 GMT
Just installed RH 6.1. I can telnet into, and, of course, ping the linux
server, but I cannot ftp. At the DOS prompt it says:
Connected to lacalena.mylinux.com
..
then after a minute, it says
Connection closed by remote host.
I ran tcpdchk, and it didn't return any errors. Any ideas on what to try
next?

Subject: "w" says "2 users" but only lists one
Date: Tue, 21 Mar 2000 20:44:13 GMT
When I run "w" on a particular server it says there are 2 users logged
in, but only lists a single user:
2:37pm up 59 days, 16:46, 2 users, load average: 0.00, 0.00, 0.00
USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT
root pts/0 remote.computer 2:37pm 0.00s 0.05s 0.02s w
There is in fact only one user actually logged in (via OpenSSH).
The output of the "who" command is:
root pts/0 Mar 21 14:37
root pts/2 Mar 17 17:04
How do I kill off the Mar 17 login, short of rebooting the machine?
A search of deja.com turned up a similar question, however it was in a
Dutch Linux newsgroup, and as I'm not Dutch, I couldn't understand the
solution...
Thanks.

the resolution was so low the icons were massive and I couldn't see even
half of most windows, any suggestions on how to fix this?

How would one go about configuring a Linux system to use only a RAMdisk
read-only mounted filesystems? What I need is a system that can have the
power cut at any time without problems. Thanks in advance for any advice.

Not bad. However, it isn't clear to me that you installed the full
base.tgz tarball. You need that (and, I think, only that) in order
to bootstrap yourself.

Check your /etc/passwd file, and check that it is mounted in the right
place. You may have to reboot using your freshly installed root partition
at some point. Until then, you may find that things are in /target/etc
rather than /etc.

With ALL the packages? I was under the impression that you had
only done a minimal install, and that you would fill in the gaps
later over a network connection or a borrowed disk drive.

Hello,
I want to give every one a heads up about a great conference that's
happening in Japan this July. The Internet Society, one of the oldest
international Internet organizations, is hosting its annual Global
Summit in Yokohama, Japan. This four day event will cover such pivotal
topics as:
-- Regulation, Policy and Governance
-- E-Commerce and E-business
-- Interactive and Multimedia
-- Mobile Internet and IP Network Appliances
-- Internet Science and Technology
-- Internet Infrastructure and Technologies
-- Third World Expansion
-- Security
-- Domain Names
-- Linux
-- Open Source Movement
Please feel free to forward/post this announcement or pass it around to
your colleagues.
Here are the logistics of the event.
INET 2000
The Internet Global Summit: Global Distributed Intelligence For
Everyone
The 10th Annual Internet Society Conference
18-21, July 2000
Pacifico Yokohama Conference Center, Yokohama, Japan
email: <[EMAIL PROTECTED]>
web: <http://www.isoc.org/inet2000/>
REGISTER AT: http://mc-net.jtbcom.co.jp/inet2000registration/
INET is the premier event in the Internet industry, providing an
international forum for advancing the development and implementation of
Internet networks, technologies, applications, and policies.
The world's Internet leaders meet at INET conferences to exchange
experiences and shape the future of the Internet. INET attendees examine
strategic issues emanating from the Internet's impact on commerce and
finance, education, technologies and societies. INET 2000 presents a
strong technical program with all papers peer reviewed by industry
experts from around the world.
*WHO ATTENDS INET CONFERENCES:*
More than 2,000 decision-makers and networking professionals involved in
extending the use and reach of Internet networks in their organizations
or countries are expected to attend INET 2000. Their roles involve
nearly every aspect of the Internet's development and operations.
*KEYNOTE SPEAKERS:*
- John T. Chambers, President and CEO of Cisco Systems, Inc.
- Dr. Ken-ichi Ohmae, international management consultant and creator of
the framework of the borderless economy.
SUPER PANELS:
Super Panel #1: Open Source Movement
Launched in 1985 by Richard Stallman, (GNU), the free source code
movement has blossomed into a broad front of projects best exemplified
by the stunning success of Linux, the Unix-like kernel launched by Linus
Torvalds in 1991. It is now challenging Microsoft's Windows NT in the
server business and is poised to invade the desktop as well. Some call
Linux the Internet Operating System and this is twice true: it could not
have existed without the Internet and a lot of machines that are making
up the Internet run on Linux. Apache, another free source code software,
powers nearly half of all Internet servers in the world. This round
table Super Panel will discuss how these two communities are rapidly
merging into one that may be the real basis for the new net economy.
Super Panel #2: Next-Generation Internet Research Projects: What's New,
What's Next and What Works?
Late-breaking news from Next-generation Internet projects will be
presented. Panelists will address their current status, next step, and
what has led them to success.
Super Panel #3: The Future of the Internet Layer
As the Internet continues to grow, there are increasing stresses and
strains on some of its foundations, such as the original numeric
addressing space and the underlying assumption of transparent
communications. The expected arrival of millions of wireless devices,
and expansion to new, very populous regions of the world, will maintain
or increase these stresses for several decades to come. The Internet
technical community has been aware of this issue for at least seven
years and has carried out various studies and new developments including
Classless Interdomain Routing, Network Address Translation and IPv6. The
panel will discuss all this and more, and attempt to discern where we
are headed next.
PROGRAM THEMES:
- Internet Infrastructure Technologies
- Internet Science and Technology for the 21st Century
- Mobile Internet and IP Network Appliances
- Interactive, Multimedia, Innovative Contents with Full Demonstrations
- Bio-Medical Issues
- Education
- E-Commerce and E-Business
- Regulation, Policy and
- Governance
iGrid2000: LIVE DEMONSTRATIONS: The potential for using global,
next-generation networks to significantly change the way science is
conducted will be showcased at INET 2000, where researchers from around
the world will collaborate in iGrid2000, sharing computing resources and
data over high-speed networks to solve complex computational programs.
