CRAY RESEARCH ANNOUNCES NEW C AND C++ PRODUCTS



EAGAN, Minn., Dec. 14, 1993 -- Continuing its commitment to C

and C++ as important programming languages in high-

performance scientific computing, Cray Research, Inc. today

announced two new products that are expected to make

programming in these two languages easier and help C and C++

programs perform better on Cray Research supercomputers. 



The two new products are the Cray Standard C Programming

Environment 1.0 and the Cray Research C++ Libraries.  The Cray

Standard C Programming Environment includes the most recent

version of the Cray Standard C Compiler (version 4.0) and

associated tools and libraries.   This is the first time Cray

Research has announced an integrated program development

environment for the C language.



"These new software products show our commitment to C and

C++ as scientific and engineering programming languages,"

said Mike Booth, head of compiler development in Cray

Research's software division.   "With an integrated approach to

our compiler products, Cray customers will receive full

programming environments supporting new languages like C++

and the newest releases of existing languages like C combined

with all the supporting tools and features tuned to these

languages," said Booth.  



He  said that the company plans to make all future releases of

Cray Research compiling technology available to customers

this way.  Fortran 77 and Ada programming environments were

previously announced.  A Fortran 90 environment is expected to

be available by year-end, 1993, he said. 



The Cray Standard C Compiler, the main component of the Cray

Standard C Programming Environment, employs the most

advanced parallel detection techniques in the industry to take

advantage of the inherent parallelism of Cray Research

supercomputing systems, according to Booth.  Cray Research's

C compiler is one of the world's premier and fastest automatic

optimizing C compilers, he said.  Adding that automatic

optimization is so reliable, it's enabled by default.  

"Cray Research has been the leader in developing numeric

extensions to make C useful for scientific programming," said

Booth.  He said this includes the ability for Cray Research's

standard C environment to handle scientific data types such as

complex numbers and variable length arrays.



Also included in the new C programming environment are

CrayTools, a compilation of X Window System-based utilities

for debugging, performance analysis, and source code analysis. 

ATExpert, a key component of the programming environment, is

an expert system that interprets performance data and offers

suggestions to improve code performance.   Additionally, users

will have access to the high-performance scientific and

input/output libraries of the Cray Fortran programming

environment. 



For Cray Research customers that program in C++, the company

now offers C++ class libraries to augment its Cray C++

Compiling System first made available in July 1992.   C++ is an

object-oriented programming language that allows users to

create supercomputer-level software applications using

familiar objects of their disciplines.  Class libraries are the

"building blocks"" for simplified application software

development and improved code maintainability, according to

Booth.  



The industry standard C++ libraries, based on library products

by Rogue Wave Software, Inc., a major supplier of scientific

class libraries for workstations and PCs, enable scientists and

engineers to write code using familiar objects such as

molecules, matrices, or meshes, he said.  This allows users to

focus on the high-level concepts of their disciplines --

automotive engineering, for example -- and reduce time spent

implementing those concepts in the software code, Booth

noted.  The Cray Standard C Programming Environment 1.0 also

gives C++ programmers enhanced debugging capabilities. 



Cray Research compiling systems translate code written in

standard languages into instructions easily understood by the

supercomputer.  These software components enable scientists

and engineers to write efficient computer programs, without

requiring knowledge of the supercomputer hardware.  



Cray Research creates the most powerful, highest-quality

computational tools for solving the world's most challenging

scientific and industrial problems.
