Irregular Coarse-Grain Data Parallelism under LPARX

LPARX is a software development tool for implementing dynamic, irregular scientiic applications , such as multilevel multilevel nite diierence methods and particle methods, on high performance MIMD parallel architectures. It supports coarse grain data parallelism and gives the application complete control over specifying arbitrary block decompositions. LPARX provides structural abstraction, representing data decompositions as rst-class objects that can be manipulated and modiied at run-time. LPARX, implemented as a C++ class library, is currently running on diverse MIMD platforms, including the Intel Paragon, Cray C-90, IBM SP2, and networks of workstations running under PVM. Software may be developed and debugged on a single processor workstation.
