is g77 good enough?

Since I work for a school of aeronautical and astronautical engineering and I'm thinking of making one of my compute servers linux based, I probably should really determine if g77 is good enough as a FORTRAN compiler.

I would think not. I talked with a grad student that uses linux and does a lot of FORTRAN work and she used PGI's compiler (Portland Group, Inc.). While it's not a good as Sun's compiler it seems to do a much better job than g77.

Oh well, I don't have the linux server yet so this is just idle chattering in my mind.


probably not

Our CFD people (that are on Intel boxes) use either the Portland or the Lahey Fortran compilers.
They tell me that g77 generates slow code.

That what I was thinking as well. I was figuring that g77 would probably be ok for undergrads but everyone else would need a better compiler. I was looking at PGI. I was also looking at Absoft. I will take a look at Lahey. So I might as well get enough license of the "good stuff" and not worry about g77.
