✦ Synopsis

A study is presented of the implementation of four different parallel programming models in a code that solves the fluid flow equations on block structured meshes. Performance results obtained on a number of distributed-memory parallel computer systems are given, in particular, for a 1024 processor Cray T3D system. Using the appropriate programming model, it is shown that excellent performance scaling can be obtained even for small problem sizes. The relative merits of each programming model in terms of ease of use, functionality, and performance are assessed. (0) 1995 Academic Press, Inc.

Data-parallel languages allow programmers to easily express parallel computations by means of high-level constructs. To reduce overheads, the compiler partitions the computations among the processors at compile-time, on the basis of the static data distribution suggested by the programmer. When exec

Adaptive applications have computational workloads and communication patterns which change unpredictably at runtime, requiring dynamic load balancing to achieve scalable performance on parallel machines. Efficient parallel implementations of such adaptive applications is therefore a challenging task
