Messaging technology, such as e-mail, has become a vital part of the way people communicate. There is a growing demand for more intelligent messaging. One promising approach is agent based messaging, where messages are programs that move through communications networks.

The Taligent frameworks rely on an extended type system that gives the ability to polymorphically copy, create, and stream objects. The Taligent system provides a platform independent interface to obtain these services. We describe our experiences in porting the extended type services to a platform that does not currently have runtime type identification (RTTI) services in its C++ compiler. We provide some usage statistics to suggest that the extended type services are heavily used in a common operation.

Interactive television is a technology for delivering television programming on demand to households and businesses. Rather than passively choosing from a predetermined set of programs at scheduled times, the viewer can request programming to be delivered to him individually on demand. This paper describes a system being developed by IBM that is in active use at customer trials. The system supports movies on demand as well as more interactive applications such as home shopping. This system as deployed today on IBM's RS/6000 series of computers supports in the hundreds of viewers, but running on the SP-2 supercomputer and its follow-ons, the system can be scaled to support thousands of interactive viewers.

Support for the operation of PowerPC symmetric multiprocessing systems was introduced with Version 4 of the AIX operating system. This paper describes its evolution from the uniprocessor Version 3 implementation. It also discusses the kernel changes to support threads which allow applications to exploit the inherent parallelism of SMP.

In the computer business, most new product designs are driven by the need to reduce the price and/or increase the performance of a customer valued set of functionality. By creating such products, vendors remain competitive and profitable. In a product line, like the HP 3000 or HP 9000, products at the low end will be designed with an emphasis on low cost, while products at the high end will emphasize performance. This paper describes a new, hardware architecture for both high end clients and midrange servers where managing cost and achieving high performance contend with each other and must be balanced in order to create the desired products. The system architecture described takes into account the technology trend of using microprocessors with superscaler and/or speculative execution pipelines in a symmetric multiprocessor (SMP) system. The characteristics of this trend demand that all other system components provide enough parallelism so that the entire system will perform well. However, providing parallel paths naturally works against managing cost. What follows are the results of an effort to create a high performance, cost effective SMP architecture which provides both technical and commercial users with an attractive set of products.

The HaL PM1 CPU is the first implementation of the 64-bit SPARC Version 9 instruction set architecture. The processor utilizes superscalar instruction issue, register renaming, and a dataflow model of execution. Instructions can complete out-of-order and are later committed in order. The PM1 CPU maintains precise state. The processor has a higher level of reliability than is currently available in desktop computers for the commercial marketplace.

The Internet is evolving rapidly into a global electronic marketplace, where buyers and sellers can meet and spontaneously transact business. This market-place is an unprecedented medium for sales, marketing, distribution, customer service, and corporate communication that will fundamentally change the structure of corporations and how they do business. We will assess this phenomenon and its implications from the perspective of CommerceNet, a consortium of nearly 80 leading US companies who have come together to field the first large-scale market trial of electronic commerce on the Internet.

A new enterprise system architecture is the basis for a family of next generation Alpha SMP server systems. By combining the industry leading performance of Digital's Alpha RISC microprocessor technology, high bandwidth IO subsystems and an efficient, high bandwidth, low latency SMP interconnect, SMP server systems based on this new architecture are able to achieve supercomputer class performance at a significantly reduced cost. This paper describes the fundamentals of this new architecture and, in particular, the novel aspects of the architecture that allow its constituent systems to achieve high performance while allowing for remarkable flexibility and expandability.

A representative sample of end user applications are grouped into a limited set of functional storage categories. Various existing and future storage technologies compete for territory in the resulting application/function space. Consideration of relevant factors such as current storage practice, costs, device and system capacity and performance, and technology growth paths explain the rapid growth of CD-ROM in the application space and suggest future rapid growth of write once CD-Recordable and mid to high performance rewritable optical storage.
