[ contact / participants ]

a programming environment in which parallel programs can be developed or restructured in a machine-independent fashion

Objectives and Approach

PREPARE's environment will be based on three tightly integrated components:

• a Parallelisation Engine guided by a set of compiler directives that specify data distribution based on the emerging standard High Performance FORTRAN
• an Interactive Engine that reports to the programmer to what extent the system can parallelise the program, indicates the obstacles preventing parallelisation, facilitates the removal by the programmer of such obstacles and provides performance measures in terms of the source code
• an efficient compilation system based on the CoSy system developed in the COMPARE project (5399) generating highly optimised code that fully exploits the intra-processor parallelism of the target machine

The implementation of the parallelisation scheme has been started and the PREPARE intermediate representation is used by all engines of the compilation system. The Interactive Engine and Execution Monitor have been designed and implementation begun.

Some strategic alliances with computer manufacturers have been established. The first commercial outcome is expected near the end of 1994.
