abstract

LPARX provides efficient run-time support for dynamic, non-uniform
scientific calculations running on MIMD distributed memory architectures,
and is intended for block structured and multilevel
applications involving structured meshes, and for particle methods.

It extends HPF's data decomposition model to provide support for dynamic,
block irregular data structures. LPARX represents data decompositions as
first-class objects and expresses data dependencies in a manner which
is logically independent of data decomposition and problem dimension.

LPARX applications are portable across a diversity of MIMD machines
and may be written in a form that is partially independent of the problem
dimension. They may be debugged on a workstation simplifying code
development.

The LPARX software is implemented as a C++ class library.

environment

LPARX runs on the Intel Paragon, the CM-5, KSR-1, nCube/2, networks of
workstations under PVM, single processor workstations, and on the Cray
C-90 (single processor at the moment). LPARX will soon run on the
C-90 in multitasked mode, and on the T3D.
Those Paragon sites without C++ support should download the paragon-gnu.tar
script, which installs the GNU g++ compiler on the Paragon.
