High Performance Fortran is the emerging standard beyond Fortran 90 and is targeted for parallel machines. Although CRI is monitoring this standard closely, there is no HPF product currently available from CRI. There are two commercial offerings of HPF for the T3D, one from the Portland Group and the other from Applied Parallel Research. Both of these products work in conjunction with CRI’s exi...

Fortran D is a version of Fortran enhanced with data decomposition speciications. Case studies illustrate strengths and weaknesses of the prototype Fortran D compiler when compiling linear algebra codes and whole programs. Statement groups, execution conditions, inter-loop communication optimizations, multi-reductions, and array kills for replicated arrays are identiied as new compilation issue...

Current Connection Machine (CM) Fortran codes developed for the CM-2 and the CM-5 represent an important class of parallel applications. Several users have employed CM Fortran codes in production mode on the CM-2 and the CM-5 for the last five to six years, constituting a heavy investment in terms of cost and time. With Thinking Machines Corporation's decision to withdraw from the hardware busi...

MATLAB is a dynamic numerical scripting language widely used by scientists, engineers and students. While MATLAB’s high-level syntax and dynamic types make it ideal for prototyping, programmers often prefer using high-performance static languages such as FORTRAN for their final distributable code. Rather than rewriting the code by hand, our solution is to provide a tool that automatically trans...

Exploiting the full performance potential of distributed memory machines requires a careful distribution of data across the processors. Vienna Fortran is a language extension of Fortran which provides the user with a wide range of facilities for such mapping of data structures. In contrast to current programming practice , programs in Vienna Fortran are written using global data references. Thu...

We describe Nestor a library to easily manipulate Fortran pro grams through a high level internal representation based on C classes Nestor is a research tool that can be used to quickly im plement source to source transformations The input of the li brary is Fortran Fortran and HPF Its current out put supports the same languages plus some dialects such as Pe tit OpenMP CrayMP Compared to SUIF t...
