Fujitsu has just jumped into the market with Fujitsu Fortran 90.

I have not run this, but they are quite friendly, and most willing to send
demo versions. It is apparently a fully intregrated openwins version wiht
popup windows and popup debuggers to beat the band. The price is about $5K

The person I dealt with was:

Fortran can cost a few bucks. If you're cheap, look around for gcc and
libg++, and use them to install f2c, a Fortran-to-C converter and
compilation system. I've used it on Sparc's, Indigo's, and NeXT stations
to produce code nearly as fast as Sun's f77 compiler.

  I know of at least four, although I can't prejudge which
  is best....

     a) SunSoft (currently @ v 3.0), f77 not yet compliant with
                f90, although they have announced an ongoing
                agreement with NAG to merge their f90 compiler
                with Sun's. Originally scheduled for late
                this year. Current status?????

     b) NAG, runs on many platforms, f90 compliant.

     c) f2c, gnu compiler which "converts" fortran to c for
             compilation by gcc.

     d) CraySoft, f90 compliant compiler for SPARC which was
                  announced end of last month. We will be
                  evaluating it starting next week to determine
                  how well it works in our enviroment. Will
                  supposedly support multiprocessing on MP

   We are currently using (a) and are pretty happy with Sun's
   compiler. We did evaluate their 'iMPact' product (v 1.0),
   which add's 'MP' support to their Fortran compiler. We were
   not terribly impressed with it! When you used the 'MP' option
   it disabled '-g' (debugging), this made it very difficult to
   get code converted and running with 'MP' support.

   (b) has been around for a couple years, but I've never used

   (c) f2c is 'freeware'.

   (d) sound's promising, and has the added advantage of being
       able to use the 'same' compiler on both SPARCs and Crays.

  Hope this helps,

  -- Bob

Without knowing your criteria, it's hard to say what is "best". the
current Sun product (f77 3.0 for solaris 2.x) "Fortran Workshop" is a
complete f77 development environment, including performance tools, GUI
based debugger (including "fix and continue"), auto-parallelizing
compiler, team oriented source control system, C compiler and etc. A
4.x version (with some features not supported by SunOS deleted) will
be announced RealSoonNow.

EPC and Fujitsu have f90 compilers and environments available.

NAG has a f90 to c xlator available.

Parasoft has a f90(sorta) to f77 xlator.

Apogee has a compiler and KAP preprocessor package. No environment
support that I know of. Capable of generating very good code, with
massive "knob" twiddling. Capable of getting very odd answers, in my
limited experience (no smilely) too.

LPI has a compiler; not very good IMNSHO opinon. Absoft may also, I've
never seen it for sale though.
