Internet enabled wireless devices continue to proliferate and are expected to surpass traditional Internet clients in the near future. This has opened up exciting new opportunities in the mobile e-commerce market. However, data security and privacy remain major concerns in the current generation of "wireless web" offerings. All such offerings today use a security architecture that lacks end-to-...

The software industry is currently in the middle of a paradigm shift. Applications are increasingly written for the World Wide Web rather than for any specific type of an operating system, computer or device. Unfortunately, the technologies used for web application development today violate well-known software engineering principles. Furthermore,they have reintroduced problems that had already ...

We introduce Transient Blocking Synchronization (TBS), a new approach to hardware synchronization for mega-scale distributed-memory multiprocessor machines. Such machines, with thousands of processors and controller based memory modules, are essentially distributed networks, and one must search for new paradigms that provide hardware synchronization support with high levels of robustness and mi...

A primary goal of research into orthogonal persistence is to simplify significantly the construction, maintenance and operation of applications in order to save software costs, extend the range of applications and improve users’ experiences. To test such claims we need relevant experiments. To mount such experiments requires an industrial-strength persistent programming platform. The PJama proj...

As more companies are beginning to adopt the e-business model, it becomes easier for buyers to compare prices at multiple sellers and choose the one that charges the best price for the same item or service. As a result, the demand for the goods of a particular seller is becoming more unstable, since other sellers are regularly offering discounts that attract large fractions of buyers. Therefore...

This trio of papers was prepared for publication in September of 1996 when the author was a member of the Desknet group in Sun Microsystems Laboratories. He is presently in the Solaris Products group. Tuning Solaris UFS Bandwidth The purpose of this paper is to provide general tuning guidelines for getting the best bandwidth possible from large files using Solaris UFS. Information on filesystem...

Many garbage-collected systems, including most that involve a stop-the-world phase, restrict GC to socalled GC points. In single-threaded environments, GC points carry no overhead: when a GC must be done, the single thread is already at a GC point. In multi-threaded environments, however, only the thread that triggers the GC by failing an allocation will be at a GC point. Other threads must be ...
