Nvidia has released a public beta of the PGI CUDA-enabled Fortran
compile. Developed in collaboration with The Portland Group , it’s
the first Fortran compiler compatible with Nvidia CUDA -enabled
graphics processing units (GPUs).

A compiler is a software tool that translates applications from the
high-level programming languages used by software developers into a
binary form a computer can execute. Developers are invited to
download the beta CUDA Fortran compiler for Mac OS X, Windows and
Linux systems from The Portland Group web site
(http://www.pgroup.com/support/downloads.php).

The PGI CUDA Fortran compiler requires the CUDA Software Developers
Kit (SDK) which is available from CUDA Zone
(http://www.nvidia.com/cuda). PGI compilers are recognized in the HPC
community for delivering world-class performance across a wide
spectrum of applications and benchmarks, according to the folks at
Nvidia.
