In this major report, we present the design and implementation of the Corba Version of the Concordia Parallel Programming Environment (CPPE), a client-server-based simulator for parallel programming environment. The purpose of the client/server version is to provide services and a rich set of graphical user interfaces for remote clients.  The challenge in the design of client/server version is to reuse the existing C/C++ code. To solve the problem, we use Corba's delegation technique to wrap the existing C/C++ application into a standard Corba object, and then we create an IDL interface for it. From the IDL interface specification, we create a Java standalone application wrapped in Corba objects that runs at client site and communicates with the server.  We design and implement client site GUIs for the application in Java/Swing.  This Corba Version of CPPE is very portable since the client site application can be installed and run in any platform. The server supports multiple users.
