Forty Exabytes of unique data will be generated worldwide in 2009. This data can help us understand scientific and engineering phenomenon as well as operational trends in business and finance. The best way to understand, navigate and communicate these phenomena is through visualization. In his opening address, Intel CTO Justin Rattner will talk about todays data deluge and how high performance computing is being used to deliver cutting edge, 3D collaborative visualizations. He will also discuss how the 2D Internet started and draw parallels to the rise of the 3D Internet today. With the help of demonstrations, he will show how rich visualization of scientific data is being used for discovery, collaboration and education.

In this paper, we describe how the memory management mechanisms of the Intel iAPX-432 are used to implement the visibility rules of Ada. At any point in the execution of an Ada® program on the 432, the program has a protected address space that corresponds exactly to the program's accessibility at the corresponding point in the program's source. This close match of architecture and language did not occur because the 432 was designed to execute Ada—it was not. Rather, both Ada and the 432 are the result of very similar design goals.To illustrate this point, we compare, in their support for Ada, the memory management mechanisms of the 432 to those of traditional computers. The most notable differences occur in heap-space management and multitasking. With respect to the former, we describe a degree of hardware/software cooperation that is not typical of other systems. In the latter area, we show how Ada's view of sharing is the same as the 432, but differs totally from the sharing permitted by traditional systems. A description of these differences provide some insight into the problems of implementing an Ada compiler for a traditional architecture.

The Intel iAPX-432 is an object-based microcomputer system with a unified approach to the design and use of its architecture, operating system, and primary programming language. The concrete architecture of the 432 incorporates hardware support for data abstraction, small protection domains, and language-oriented run-time environments. It also uses its object-orientation to provide hardware support for dynamic heap storage management, interprocess communication, and processor dispatching.
