Using MeDLey to resolve the Vlasov equation
Résumé
Explicit parallelism relies on transmissions of messages between processes. However, as workstations are not intended to manage this kind of communications, it is necessary to use communication libraries, known as Message Passing. Currently, only MPI (Message Passing Interface) is still used, and its use became more complex. In order to solve this problem, a new language called MeDLey was developed, its purpose is to allow to the users an easier parallelism programming based on communications using Message Passing. In this paper, we will first overview the basics of the MeDLey syntax and semantics, before talking about the experimentation part of this language. This work is completed within team RESEDAS (Computer networks and Distributed systems) with the LORIA and INRIA Lorraine within the framework of a collaboration with the CCH (Lorraine Center of Competence in Modeling and Calculation with High Performance).
