In a team of six software engineers, we are currently developing the portable integrated tool environment Annai [1] for distributed-memory parallel processors. Annai consists of a High Performance Fortran (HPF) compiler, extended for the support of unstructured computations, a performance monitor and analyzer [2], and a source-level debugger [3] for distributed programs, all sharing a common user-interface. The recently-defined Message Passing Interface (MPI) serves as our low-level machine interface. Our HPF extensions are implemented by a compiler generically called Parallelization Support Tool (PST). All PST HPF extensions are fully supported by both the performance analyzer and debugger. |
