Dear Alain,
Thank you for your attention to the License agreement for Intel Fortran.
We once bought PGI Fortran on Linux (RedHat X i386),
http://www.pgroup.com/resources/accel.htm
more than 10 years ago. It was good at that time.
However, recently our collaborators in other institute strongly
recommend that "Intel Fortran is now very good !".
By the way, we have several old machines still alive.
One is Alpha server, ES40 (667MHz 4 CPU).
$ uname -a
OSF1 xxxxx.riken.jp V4.0 1530 alpha
$ f77 -version
Compaq Fortran V5.4-1283
Compaq Fortran Compiler V5.4-1283-46ABA
This is DEC Fortran and still alive. This DEC fortran is good!!
Another very old machine is OpenVMS AXP V6.2 (AS-2100 5/250)
$ show sys

This is also DEC Fortran and this server AS-2100 5/250 still alive
more than 17 years without maintenance contract.
Of course, now our main OS of servers is Scientific Linux . But among
them,
some old machines are still alive very quietly :-)
Regards,
Takashi

Hi Guys,
(snif)
I do not know squat about Fortran compilers.
Question: is there a good Fortran environment I should put on
his new computer? Bear in mind when you answer, that if my customer
likes your suggestion, doctoral engineering students will be required
to use it (tormented with it).
Many thanks,

My recommendation is Intel Fortran compiler.
http://software.intel.com/en-us/articles/intel-compilers/
Especially, for the Non-Commercial Software Development,
Free Download is available.

As a member of a french research laboratory which uses Intel
compilers, I must add a precision : Non Commercial use means that you
are not paid for your work, otherwise Intel compilers are not free,
even on Linux. See Intel FAQ :
http://software.intel.com/en-us/articles/non-commercial-software-faq/
And especially the first answer :
*"What does noncommercial mean?*
Non-commercial means that you are not getting compensated in any form
for the products and/or services you develop using these Intel®
Software Products."
It is not the case for must of us.
So, for free use, go for gfortran, but my experience is that indeed
Intel compilers make faster code.
