Digital Equipment Corporation has been bought by
COMPAQ which has been bought by HP.
DEC Fortran 90/High Performance Fortran is a native
Fortran 90/HPF compiler that includes support for parallel execution.
DEC Fortran 90 supports all standard FORTRAN 77 and Fortran 90
programs for standard serial execution, as well as HPF programs for
parallel execution. Message passing for parallel programs is provided
by Digital's PSE (Parallel Software Environment), a transparent
run-time environment which provides optimized message passing for HPF.
Digital claims HPF
performance comparable to hand-tuned PVM (Parallel Virtual Machine)
code in a wide range of cases.
For parallel execution, a package including DEC Fortran 90 together
with Digital's PSE is available for Alpha systems running Digital UNIX
(OSF/1). For serial execution, DEC Fortran 90 is available for
Alpha systems running either Digital UNIX (OSF/1) or OpenVMS.
Since I have access to a Digital UNIX system from February 1996,
I have now written a special document on
Digital Fortran V5.1 includes full support for Fortran 95.
