Doctor Fortran in "The Future of Fortran"
Von Steve Lionel (Intel) Veröffentlicht am 27.03.2015 4
In November 2014, I led a session at SC14 (the event formerly known as “Supercomputing”) titled “The Future of Fortran”. I invited representatives from other vendors and members of the Fortran standards committee to participate, and had some accept, but when it came time for the session, I was up t…
GNU Terry Pratchett

  xkcd This post contains no Fortran. British author Sir Terry Pratchett died March 12, 2015 at age 66, finally succumbing to what he called "The Embuggerance", a rare form of Alzheimer’s disease, posterior cortical atrophy (PCA), which affects the rear portions of the brain. An extensive obitua…
Doctor Fortran in "It's a Modern Fortran World"
Von Steve Lionel (Intel) Veröffentlicht am 30.12.2013 0
I recently received a copy of "Numerical Computing with Modern Fortran", by Richard Hanson and Tim Hopkins, and noted how many books on Fortran are being published recently with "Modern Fortran" in the titles. It turns out this is not a new phenomenon - a search on Amazon.com shows that this phrase…
Has it really been 35 years?
Von Steve Lionel (Intel) Veröffentlicht am 02.10.2013 6
I knew this date was coming up, but I had forgotten about it for a while until my manager reminded me - October 2, 2013 marks my 35th anniversary "at Intel". I put that in quotes because Intel "grandfathered" my time at DEC and Compaq. It was October 2, 1978, when I walked into DEC's facility in Te…
Doctor Fortran Goes Dutch: Fortran 2015
Von Steve Lionel (Intel) Veröffentlicht am 08.08.2013 1
The ISO Fortran Standards Committee held its annual meeting in Delft, The Netherlands, in late June. I represented Intel at this meeting where the focus was on completing the set of requirements for the next revision of the Fortran standard, to be called Fortran 2015. You can read my earlier post o…
Doctor Fortran in "Source Form Just Wants to be Free"
Von Steve Lionel (Intel) Veröffentlicht am 11.01.2013 0
In the beginning, there was only one source form for FORTRAN (as it was then known) programs. Each statement was exactly 72 characters long - no more, no less. (See note below.) Columns 1-5 were for statement labels, whole line comments were indicated with a C in column 1, and column 6 was reserved…
Doctor Fortran in "I Can C Clearly Now, Part I"
Von Steve Lionel (Intel) Veröffentlicht am 11.05.2012 1
Spend any time in the comp.lang.fortran newsgroup, or other places where programming languages are discussed, and you’ll soon see a new “Which is better, Fortran or C?” thread show up. These never fail to produce heated comments from people who should know better. My answer is that neither is “bett…
Doctor Fortran Gets Explicit - Again!
Von Steve Lionel (Intel) Veröffentlicht am 05.01.2012 11
Nearly 11 years ago (!) I wrote an item for the Visual Fortran Newsletter on explicit interfaces in Fortran. In recent weeks, I have had to refer quite a few customers to this article, suggesting that many Fortran programmers don't understand the role and rules of explicit interfaces. However, when…
Doctor Fortran in "Lest Old Acquaintance Be Forgot"
Von Steve Lionel (Intel) Veröffentlicht am 23.12.2011 3
In some of my earlier posts I've discussed new features in the Fortran language that might be unfamiliar to some.  But this time I'm going to go the other way and describe some really old language features - so old that many newer Fortran programmers are mystified when they see them - but these fea…
The Real Doctors of Fortran
Von Steve Lionel (Intel) Veröffentlicht am 22.09.2011 7
In this blog, I refer to myself as "Doctor Fortran".  It's a joke that started more than ten years ago when I decided to write an "advice column" for what was then the Digital Visual Fortran Newsletter.  Everyone liked it so much I stuck with it, but I've always been aware of the people who deserve…
