Cobra: A CORBA-compliant programming environment for high-performance computing

In this paper, we introduce a new concept that we call a parallel CORBA object. It is the basis of the Cobra runtime system that is compliant to the CORBA specification. Cobra is being developed within the PACHA Esprit project. It aims at helping the design of high-performance applications using independent software components through the use of distributed objects. It provides the benefits of distributed and parallel programming using a combination of two standards: CORBA and MPI. To support CORBA parallel objects, we propose to extend the IDL language to support object and data distribution. In this paper, we discuss the concept of CORBA parallel object.
