I'm sorry if this is an already covered topic, and if so, please point
me to the archive so I can catch up.
I am wondering if the latest releases of FB^3 takes advantage of
vectorization algorithms built into the the G4 chip (i.e. velocity
engine, AltiVec). There has been an interesting exchange on G4
performance (and the lack of Mac Apps that take advantage of the full G4
capabilities) on Ric Ford's MacInTouch site (http://www.macintouch.com)
and it got me to thinking whether or not FB^3 provides a means to
utilize these
features as well.
A very interesting Fortran example can be found in a paper entitled "An
Evaluation of PowerMac G4 Systems for FORTRAN-based
Scientific Computing with Application to Computational Fluid Dynamics
Simulation" at
http://ad-www.larc.nasa.gov/~cah/NASA_G4_Study.pdf
I have some old Fortran code that I may port to the Mac and I'm debating
on recasting the code into FB or keep it as Fortran and run
it with Absoft Fortran (which offers a means to optimize the code to
utilize the G4's vectorization capabilities) or in LINUX. If I compile
source in FB^3, can it be optimized to take advantage of AltiVec's
capabilities?
Thanks - John Robbins

and support...)
