Message Passing has become one of the most popular parallel programming paradigms because of its ease of use. Conversely, using it efficiently often requires lots of efforts, when designing a distributed application. Finally, such an application often requires optimization, since performances are not always as good as expected.

With MeDLey, we propose an abstract approach to message passing. The basic idea is to provide a language that might be used to specify all communications within a distributed application. With this specification, the user does not have to care about the implementation any more, and leaves it to the compiler's charge. Finally, the aim of this approach is to achieve more efficiency by generating specific communication primitives rather than using generic message passing libraries.

MeDLey has followed two main steps: MeDLey-0 was the first version of the compiler. It was able to generate C++ and MPI communications primitives, mainly to help the user in the design process. MeDLey-1 now tries to gain more efficiency by implementing communications with dedicated devices like shared-memory or AAL5 for ATM-based clusters of workstations.
