[comp.misc] Sun-3, Sun-4 scientific comparisons

mlj8e@dale.acc.Virginia.EDU (Michael L. Johnson) (04/16/88)

In a recent article the question was ask if anyone had compared
a SUN-3 and SUN-4 for scientific calculations.  Well after checking
the SUN's and several other machines I decided to purchase a RISC
machine, but not the SUN-4.
The machine I picked is the Silicon Graphics 4D/70.  The reason 
that I picked this machine is that when I tested them with my
scientific programs I discovered that the FORTRAN compiler on
the 4D/70 generated fewer errors.  It should be noted that the
programs which I tested all run perfectly on our VAX-VMS machines
and on out PDP-11 RT-11 machines.  With one 27,000 line program
the Silicon Graphics machine claimed that two statements were
out of order and the SUN machine generated numerous errors in
translating from VMS FORTRAN to UNIX FORTRAN.  The net result
was that I purchased the machine with the better FORTRAN
compiler.
I know that I should be using a more modern language, but I
would like to state that I have a B.S. in computer Science
and about 20 years experience in programming computers, and
I have programmed in several more modern languages, like PL/1,
C and PASCAL as well as a number of languages that most of you
have never heard of like FOCAL and SAIL.
The bottom line is that I use FORTRAN because I like it better
than any other language that I have ever used.
Incidently, FORTRAN was not the first language that I learned,
first I learned ALGOL, then PDP-5 assembler, then FOCAL, then
CDC-3300 assembler, and then FORTRAN.
