POP-C++ language is an extension of C++ that implements the parallel object model with the integration of resource requirements into distributed objects. We try to keep this extension as close as possible to C++ so that programmers can easily learn POP-C++ and that existing C++ libraries can be parallelized using POP-C++ without too much effort.

POP-C++ run-time is an object-oriented open design which aim at integrating different Grid and distributed computing toolkits into an infrastructure for executing requirement-driven object-oriented applications. Our idea is to use objects to serve objects: the system provides basic services for executing objects. Again, each service is implemented as an object with an well-defined "virtual" interface which is customizable for different Grid toolkits by the object (service) inheritance. A new type of services called application scope service is introduced into the POP-C++ architecture which serves application related tasks. These services are instantiated inside each application and are accessible from other standard system-wide services to perform application-specific tasks. The result of this open design is the POP-C++ runtime system which can be used to glue today and tomorrow Grid toolkits to create a broader environment for executing high performance computing applications.
