The Tandem NonStop System is a fault-tolerant [1], expandable, and distributed computer system designed expressly for online transaction processing. This paper describes the key primitives of the kernel of the operating system. The first section describes the basic hardware building blocks and introduces their software analogs: processes and messages. Using(More)
T he advent of fast, power-thrifty microprocessors has made possible pocket-size computers with performance approaching that of desktop PCs. This new class of mobile computers enables applications and user-interface modalities not feasible with traditional personal digital assistants and cell phones, while placing new demands on batteries and power(More)
is part of Compaq's Corporate Research group. Our focus is research on information technology that is relevant to the technical strategy of the Corporation and has the potential to open new business opportunities. Research at WRL ranges from Web search engines to tools to optimize binary codes, from hardware and software mechanisms to support scalable(More)
Introduction Bigloo is a Scheme compiler developped at Inria-Rocquencourt in the Icsla team. This is the continuation of Nitsan S eniak's work on the compilation of functional languages S en91] and Christian Queinnec's modules for Scheme QP91]. I would like to address special thanks to Joel F. Bartlett for his Scheme-to-C compiler Bar89]. The rst version of(More)
We search for the technicolor process pp-->rhoT/omegaT-->WpiT in events containing one electron and two jets, in data corresponding to an integrated luminosity of 390 pb(-1), recorded by the D0 experiment at the Fermilab Tevatron. Technicolor predicts that technipions pi(T) decay dominantly into bb, bc, or bc, depending on their charge. In these events b(More)
Many modern garbage collectors [4] recover space by copying. Using an initial "root" set of pointers which are stored in known locations, all accessible objects are copied into a "new space". Two of the attractive properties of such a collector are that it results in memory compaction and it can have a running time proportional to the amount of accessible(More)
Anomalous Wtb couplings modify the angular correlations of the top-quark decay products and change the single top-quark production cross section. We present limits on anomalous top-quark couplings by combining information from W boson helicity measurements in top-quark decays and anomalous coupling searches in the single top-quark final state. We set limits(More)
