Lahey Fortran 90 to Use Intel Optimizing Code Generation Technology 

Fortran to be Optimized for Intel486 and Pentium Processors

Incline Village, Nevada, June 4, 1993-Lahey Computer Systems is pleased to
announce an agreement to use Intel's optimizing code generation technology
in their Fortran 90 language system.

By using Intel's code generation technology, this 32-bit Fortran will take
full advantage of the Intel486 and Pentium processor architectures. The
combination of Lahey's compiler front-end technology and Intel's highly
optimizing code generation technology will establish the Lahey Fortran 90
as the preeminent Fortran language system for the PC platform.

President of Lahey 

"We are excited about combining our Fortran 90 front end compiler
technology with Intel's optimizing code generation technology," said Tom
Lahey, President/CEO of Lahey Computer Systems. "Using Intel's technology
will bring our product to market earlier and give Lahey a competitive
advantage in execution speed. Fortran users can be assured our Fortran 90
will be a compiler-based language system and not a product that resorts to
translation. We plan to continue incorporating Intel's compiler technology
as our language systems support future generations of their
microprocessors."

Lahey/Intel Technology Relationship 

"Intel has developed optimizing code generation technology to facilitate
the availability of compilers that produce optimized code for the Intel486
and Pentium processors," said Riaz Haq, Marketing Manager at Intel's
Architecture and Software Technology Group. "We are pleased that Lahey
will be using the Intel code generation technology to bring an optimizing
Fortran 90 compiler product to the market for Intel-based platforms."

Optimizations for Intel486 and Pentium Processors 

Lahey Fortran 90 will not only let programmers use all the new features
available in the Fortran 90 Standard, but the highly optimizing Intel code
generation will put Lahey Fortran 90 at the forefront of compiler
performance. The Intel technology implements both classical and advanced
optimization techniques. Although targeted for peak performance on the
Intel486 and Pentium processors, Lahey Fortran can also be used on
386-based systems. The optimizing code generation technology fully
exploits the performance potential of architectural attributes such as
complex addressing modes. By selecting the optimum addressing modes, the
compiler saves valuable cycles that would be wasted by compilers that do
not emphasize X86 family instruction selection. The result of these
architecture-specific optimizations is superior application performance on
the Intel486 and Pentium processors. "We expect to have the fastest
execution speed of any Fortran compiler running on the Intel486 or Pentium
processors," said Bruce Bush, Chief Technical Officer at Lahey Computer
Systems.

Fortran 90 Replaces 77 

Scientists, engineers, and professional programmers will be able to
downsize their existing 77 programs with Lahey Fortran 90 because it is a
superset of Fortran 77. Combined with the performance of the 3 86, 486,
and recently released Intel Pentium processors, Lahey Fortran 90 will make
it highly cost-effective for companies to move their Fortran applications
from mainframe and mini-computers to personal computers. Using Lahey
Fortran 90 will also make writing new code easier because of the
availability of new language features. In optimizing older programs or
developing new applications, Lahey Fortran 90 users will find their source
code to be more portable, smaller, and faster than corresponding Fortran
77 code. Some of the key features of the Fortran 90 Standard:

* Arrays - powerful and more efficient ways of handling arrays
* Structures - combine intrinsic and user-defined types
* Modules - using this new program unit, package code and data 
  in reusable units
* Pointers - create data structures such as trees and linked
  lists
* ALLOCATE - size your program based on user resources.
* Modem Control Constructs - CASE, DO / END DO, DO WHILE, CYCLE,
  EXIT
* Kind - select data type based on required precision without
  knowing precision of processor

With the new features found in the Fortran 90 Standard, highly optimized
Intel code generation, and Lahey's reputation for industry-leading
compilers, Lahey expects Fortran programmers to begin replacing their
Fortran 77 language systems as soon as Lahey Fortran 90 becomes
available.
