Abstract:
In the context of parallel and distributed computation, the
currently existing numerical libraries do not allow code reuse.
Besides, they are not able to exploit the multi-level parallelism
offered by many numerical methods. A few linear algebra numerical
libraries make use of object oriented approach allowing modularity
and extensibility. Nevertheless, those which offer modularity
together with sequential and parallel code reuse are almost
non-existent. We analyze the lacks in existing libraries and propose
a design model based on a component approach and the strict
separation between computation operations, data definition and
communication control of applications. We present then an
implementation of this design using YML scientific workflow
environment jointly with the object oriented LAKe (Linear Algebra
Kernel) library. Some numerical experiments on GRID5000 platform
validate our approach and show its efficiency.
