The development of sophisticated runtime support forms the foundation
of our research effort. We have developed the CHAOS library, a runtime
support library that couples partitioners to rays, generates optimized
communication schedules. The CHAOS library also contains a wide range
of efficient partitioners which are based on data access patterns of a
problem, computational load information and problem geometry. We have
implemented address translation methods which support irregular
mappings by using highly optimized page-based translation tables.
Meta-ChaosThe related papers describes a framework for providing the ability to use multiple specialized data parallel libraries and/or languages within a single applications. The ability to use multiple libraries) is required in many application areas, such as multidisciplinary complex physical simulations and remote sensing image database applications. An application can consist of one program or multiple programming that use different libraries to parallelize operations on distributed data structures. The framework is embodied in a runtime library called Meta-Chaos that has been used to exchange data between data parallel programs written using High Performance Fortran, the Chaos and Multiblock Parti libraries developed at Maryland for handling various types of unstructured problems, and the runtime library for pc++, a data parallel version of C++ from Indiana University. Experimental results show that Meta-Chaos is able to move data between libraries efficiently, and that Meta-Chaos provides effective support, for complex applications.Multiblock PartiMultiblock Parti is a runtime support library for distributed memory parallel machines. This library provides the support required for parallelization of codes in which:
