Major Research Projects and Support (see http://swig.stanford.edu for complete details) Recovery-Oriented Computing. Application of Internet-service dependability techniques to other complex software systems, and identification of structural properties of software that allow the application of such techniques. Crash-Only Software (funded by Usenix fellowship, SNRC, and NSF CAREER) focuses on multi-level reactive and prophylactic restarts as a structured method of realizing high availability, and investigates what software structure and software engineering practices are necessary to support software whose default shutdown method is crashing; since CS has had limited success in applying formal proofs of software invariants to complex systems, this approach permits us to enforce invariants “from the outside” of components by allowing a predictable and simple-to-reason-about failure and recovery model. We are exploring crash-only design in the context of both purpose-built subsystems (how do you build crash- only applicatiosn?) and generic applications running on popular middleware (how much can you do for unmodified applications by modifying only the middleware?). Recent research results from this effort are being integrated into commercial prototypes or products at Sun Microsystems, Amazon.com, and eBates.com. As a side project, Satellite IP infrastructure (joint work with Stanford Space Systems Development Lab, funded primarily by NASA Glenn Research Center and NASA Graduate Fellowship) applies these techniques specifically to the design of a robust, affordable federation of autonomous Satellite Ground Stations.

Ubiquitous Computing/Interactive Workspaces. Interdisciplinary project with Profs. Patrick Hanrahan (Graphics) and Terry Winograd (HCI). We are developing a programming model, software infrastructure, and implemented prototype for ubiquitous computing spaces such as technology-enhanced meeting rooms with large displays. A recent key result is the identification of a tuplespace-like coordination model as the most appropriate programming model for such spaces that meets the relevant design constraints, exhibits robustness worthy of infrastructure software, and can be implemented with adequate performance. Prototype was deployed at 4 Stanford sites as well as KTH Royal Inst. of Tech. (Stockholm, Sweden) for regular use, and sporadically at other research labs (about 100 downloads total); more mature version is being deployed now (Winter 04) in Meyer Library for use by all Stanford students and for continued user studies on how students use interactive collaborative spaces.

Selected Recent Publications in Recovery-Oriented Computing (excluding current submissions) The underlying theme in my work in this area may be summarized as follows. Decompose the hard problem of generic failure detection and rapid recovery into two composable subproblems: first, engineer the system to expose a generic, low-cost, and fine-grained corrective mechanism (“micro-recovery”) that is safe and inexpensive to try, likely to be salubrious, and will at least do no harm; second, map the structure of the system onto models that allow the use of well- known rigorous techniques to characterize system behavior and localize failures so that ‘microrecovery’ can be applied. Althuogh each idea is useful, their combination is particularly appealing because inexpensive recovery allows the use of well-understood formalisms to characterize system behavior and localize failures, despite the fact the mapping between the formalism and the system is highly imperfect. Our position paper and initial proof-of-concept [1] [2] argued for fine-grained and coarse-grained rebooting as a well- understood recovery mechanism with salubrious properties, and proposed that the disadvantages associated with rebooting (long latency and possible state loss leading to correctness problems) should be addressed by rethinking system design to tolerate rebooting better. Our overall proposal combines crash-only design [4] (which includes application-generic fine-grained rebooting) with generic failure detection and localization. The latter problem is difficult because it requires characterizing the behavior of a complex system of black boxes; it is well-accepted that our understanding of the behavior of such systems is coarse at best. Hence we investigated statistical methods of localizing failures in generic componentized applications [3] , using dynamic fault injection to characterize failure propagation in componentized applications [5] , addressing workload-surge-related failures using free-market auction techniques [7] All of these approaches map system properties onto well-known rigorous frameworks with substantial literatures, but since the mapping is imperfect, they rely on the simplified failure management afforded by low-cost micro-recovery. Since preserving correctness in crash-only design requires separation of data recovery from process recovery, we extended previous literature on consistency/availability tradeoffs to design persistent-state storage systems optimized for fast safe reboot as the only recovery technique. We demonstrated that fast recovery in these systems can indeed be exploited to simplify failure management using well-understood pattern recognition algorithms [8] [15] . We subsequently combined these with a microrebootable generic application server [12] to obtain a true crash-only platform as we had originally proposed, showing that the low recovery cost of crash-only design makes it possible to combine it with aggressive statistical anomaly detection despite nontrivial false positive rates [14] . (Note: HotOS and WIAPP are highly selective standalone workshops with refereed published proceedings that are regularly cited. HotOS solicits papers describing highly innovative directions with initial results; WIAPP solicits papers with more substantial results.) [1] G. Candea, A. Fox.

Selected Recent Publications in Service-based and Ubiquitous Computing My ubicomp work focuses on identifying and providing the “right” software abstractions for building collaborative applications for interactive workspaces (“iRooms”), which are shared spaces with large public displays. “Right” comprises three elements: portability (applications are not tied to the physical environment for which they are developed); extensibility (new software and hardware elements can be rapidly integrated, to avoid quick obsolescence and allow for flexible evolution with no “flag days”); and robustness (frequent hardware and software failures are facts of life in a heterogeneous and dynamically-changing environment, and the software must treat these as normal rather than exceptional cases). Although various previous systems addressed one or sometimes two of these, none addressed all three effectively. Our initial ideas were developed in the context of bringing handheld devices into our testbed iRoom [16] and subsequently developing the EventHeap, a set of general extensions to the tuplespace model to facilitate a more general coordination mechanism for entities in an iRoom [18] . Building on the EventHeap allowed us to investigate a quintessential ubicomp problem in the context of the iRoom, namely the rapid integration of new services and the ability to quickly generate human interfaces for those services on a broad range of UI devices; we developed a flexible framework called iCrafter for doing this [17] and later extended it for the case in which users want to bring their preferred UI’s with them as they roam across different iRooms [20] . Following a similar methodology, we subsequently developed the PatchPanel [22] [27] , which does for physical interaction devices what iCrafter does for software services and also provides a general finite-state-machine model for expressing sophisticated physical interactions and translating them to actuators on existing iRoom services. Extensive experimentation with the EventHeap and the services built on top of it allowed us to quantitatively demonstrate meeting our goals of portability, extensibility, and robustness [25] . We then distilled these lessons into a portable “appliance” version of the iRoom that combined the most commonly used iRoom features with support for nomadic users [24] ; this is the basis of the Meyer TeamSpace which has now been deployed for general student use at Stanford as a computer-aided collaboration facility. The service-interoperation work also led to the investigation of interoperation for more general network services [19] [23] [29] and of higher-level abstractions for expressing compositions of such services [28] , both of which extend existing work in software engineering and data integration with the lessons learned from ubiquitous-computing service interoperation.
Note: WMCSA is standalone high-quality workshop with published proceedings, a 25% (typical) accept rate, and a focus on work significantly underway rather than position papers.
