In this research, We introduce two probabilistic mechanisms to
certificate parallel applications on distribute architecture supposing
that there are no oracles on which we depend on certification, in
addition to introducing cost model of two mecha
nisms and compare
them.
In this research, we are interested in parallel applications, which
are represented by data-flow graph that is built dynamically during
the execution and which are executed in a wide distributed
heterogeneous and dynamic environment and these applications
use the principle of work stealing to distribute the tasks among the
processors.
We introduce an auto adaptive strategy enables to write a parallel
algorithm adapts to the number of available resources at allocated
parallel environment to execute the parallel program. The parallel
applications we are studying which are represe
nted by data-flow
graph which built dynamically during the execution. The new
suggested strategy is based on coupling of a sequential algorithm
and a parallel one and relies on the principle of work stealing in
the tasks scheduling. We offer a study of the complexity of the
adaptive algorithm and analyze its performance on processors
and compare it with a performance of a classic parallel algorithm.
