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…
Introducing Intel® Fortran Studio XE 2011

Let us return to those thrilling days of yesteryear. Yes, I mean November 2010 when Intel® Parallel Studio XE was first released. This suite of high-performance computing development tools included new versions of the Intel C++ and Fortran compiler products, (now renamed "Composer XE"), and two new…
Thirty Years of Zonker Kookies

It is a beautiful autumn day here in Southern New Hampshire. The air is clear and crisp, the sun is bright and the trees have (finally!) brought out some color, which I can see looking out the window near my cube.  But soon, I will pack up the rest of my things and leave that view, and the cube, fo…
Doctor Fortran in "Think, Thank, Thunk"
Von Steve Lionel (Intel) Veröffentlicht am 02.09.2009 2
One of the various responsibilities I have is for the compiler samples (both Fortran and C++).  For Intel Visual Fortran, we have a lot of samples - for the other compilers, fewer.  The Windows Fortran samples are a mixed lot; some came to us from Microsoft Fortran Powerstation (with or without ext…
Doctor Fortran in "I've Come Here For An Argument, Side 2"
Von Steve Lionel (Intel) Veröffentlicht am 10.07.2009 11
My earlier post, "I've Come Here For An Argument", was very popular with my fellow support engineers, as it provided a convenient answer to questions they frequently receive.  (For me too, which in part is why I wrote it!) But some people (cough, Ron, cough) are never satisfied, and I've been asked…
Doctor Fortran in "Revert! Revert! The End (of the format) is Nigh!"
Von Steve Lionel (Intel) Veröffentlicht am 01.07.2009 4
Recently, a customer wrote in our User Forums that he wanted to write out the values of an array, all in one line, where the number of elements was not known at compile time.  His first attempt at this was:write (30,'(2x,f8.2)') array and he was dismayed to find each element written on a new line. …
Doctor Fortran in "I've Come Here For An Argument"
Von Steve Lionel (Intel) Veröffentlicht am 31.03.2009 14
One of the most fundamental aspects of Fortran programming is passing arguments to procedures.  It is also one of the most misunderstood aspects.  In this space today I'll try to make things clearer. First, some terminology.  In Fortran, there are "actual arguments" and "dummy arguments".  An actu…
Doctor Fortran in "Too Much of a Good Thing?"
Von Steve Lionel (Intel) Veröffentlicht am 23.01.2009 13
A lot of Fortran programmers take the "belt and suspenders" approach to coding, with explicit declarations of every attribute they want for a symbol.  In general, this is good practice, especially when combined with IMPLICIT NONE to force you to say what you mean.  But some programmers take this a …
It was thirty years ago today
Von Steve Lionel (Intel) Veröffentlicht am 02.10.2008 8
Today is my thirtieth anniversary of working for Intel, but that includes my years at DEC and Compaq.  As an actual Intel employee, it's a bit over seven years.  Anyway, I thought this would be a good opportunity to reminisce. I imagine most of you will find this boring; if so, feel free to go read…
What Happens in Vegas...
Von Steve Lionel (Intel) Veröffentlicht am 12.09.2008 3
110 degrees in the shade, 9 Fortran geeks and dozens of comments and complaints about Fortran: it must be another J3 meeting in Las Vegas!   J3 is the US Fortran Standards Technical Committee, a subcommittee of the International Committee for Information Technology Standards (INCITS).  J3 works clo…
