Future data center configurations are driven by total cost of ownership (TCO) for specific performance capabilities. Low-latency interconnects are central to performance , while the use of commodity interconnects is central to cost. This paper reports on an effort to combine a very high-performance, commodity interconnect (HyperTransport) with a high-volume… (More)
Executive Summary HyperTransport 3.10 is the best open standard communication technology for chip-to-chip interconnects. However, its extraordinary features are of little help when building mid-and large-scale systems because it is unable to natively scale beyond 8 computing nodes. Therefore, it must be complemented by other interconnect technologies. The… (More)
The main purpose of this paper is to introduce and study the behavior of minimum ϕ -divergence estimators as an alternative to the maximum-likelihood estimator in latent class models for binary items. As it will become clear below, minimum ϕ -divergence estimators are a natural extension of the maximum-likelihood estimator. The asymptotic properties of… (More)
We present the notion of k-intolerant bi-capacity, extending to the case of bipolar scales the notion of k-intolerant capacity recently proposed by Marichal. In a second part, we extend to the bipolar case the notion of veto criteria.
