Prototyping Parallel Applications Based on Divide and Conquer Strategy
Dvořák Václav, prof. Ing., DrSc.
The paper addresses a problem of parallel implementation of
divide-and-conquer algorithms, whose performance is not always
satisfactory. Questions like depth of recursion, multiple processes per
processor, communication architecture and overhead, etc., are analyzed
and the template for prototyping D&C algorithms in Transim language
is explained. Prototypes of parallel D&C programs can be executed
and their performance estimated before developing the code in detail.
The technique is useful for programs with message passing as well as
with shared variables. As an example a prototype of a parallel 1D-FFT
benchmark targeted both to a distributed memory machine and to a SMP
have been developed and simulated. The experiments show that the
template can be used for quick estimation of performance and
suitability of D&C approach in any given application.
