2 System Requirements

The ADAPTOR source to source translation , the different ADAPTOR runtime systems , and the compiler driver are available as C programs and require only a C compiler and the Gnu m4 Macro Processor.

For the generated code to be compiled, linked and run, the following components are required:

• A FORTRAN 77 compiler is sufficient for compiling a parallel program based on usual array syntax. If the input program contains modules, derived data types, pointers or if some other special features of Fortran 90 are used, a Fortran 90 compiler is required.
• The distributed memory execution model for HPF programs (-hpf -dm, see Figure 1) requires a MPI message-passing library.
• The shared memery execution model (-sm can be chosen for OpenMP (-omp) and HPF programs (-hpf) and is based on a PThread library that must be available in this case.
• A parallel programming environment in which parallel programs can be loaded and executed on a parallel machine.

Note: The Fortran and C compiler do not have to support OpenMP as thread parallelism is exploited directly via PThreads.
