Industry three-tier view of enterprise = computing

Today's heterogeneous interoperating hybrid server architecture. High-performance commodity computing involves adding high performance in the third tier.

Integration of Object Technologies (CORBA) and the Web=3D

Collaboration in today's Java Web Server implementation of the three-tier computing model. Typical clients (top right) are = independent, but Java collaboration systems link multiple clients through object (service) sharing.

A parallel computer viewed as a single CORBA object in a classic host-node computing model. Logically, the host is in the middle tier and the nodes in the lower tier. The physical architecture could differ from the logical architecture.

Each node of a parallel computer instantiated as a CORBA object. The ``host" is logically a separate CORBA object but could be instantiated on the same computer as one or more of the nodes. Via a protocol bridge, one could address objects using CORBA with local parallel computing nodes invoking MPI and remote accesses using CORBA where its functionality (access to many services) is valuable.

A message optimization bridge allows MPI (or equivalently Globus or PVM) and commodity technologies to coexist with a seamless user interface.
