Mass Properties of the Union of Millions of Identical Cubes
We present an algorithm and implementation, UNION3, for computing mass properties of the union of many identical axis-aligned cubes. This implementation has processed 20,000,000 cubes on a dual processor Pentium Xeon workstation in about one elapsed hour. The ideas would extend to the union of general polyhedra. UNION3 works by combining three techniques. The first is a set of local topological...
متن کاملMillions of 'snips' will harm millions of men.
To the Editor: No one knows how many people die due to HIV-related causes in South Africa every year. According to the latest statistical release, HIV is the 9th leading underlying cause of death in the country.1 This is hard to believe. Research has shown that only about 25% of all deaths related to HIV are notified as such2 – either ‘HIV’ as an underlying or contributing cause of death is lef...
متن کاملOn Millions of Cores ∗
Petascale parallel computers with more than a million processing cores are expected to be available in a couple of years. Although MPI is the dominant programming interface today for large-scale systems that at the highest end already have close to 300,000 processors, a challenging question to both researchers and users is whether MPI will scale to processor and core counts in the millions. In ...
متن کاملAfter All, Only Millions?
An update on the census of species of Archaea and Bacteria published recently in mBio (P. D. Schloss, R. A. Girard, T. Martin, J. Edwards, and J. C. Thrash, mBio 7:e00201-16, 2016, http://dx.doi.org/10.1128/mBio.00201-16) showed again that, despite ever-increasing sequencing efforts, the PCR-based retrieval of 16S rRNA genes is approaching saturation. On average, 95% of the genes analyzed today...
متن کاملMining millions of metaphors
One of the first decisions made in any research concerns the selection of an appropriate scale of analysis – are we looking out into the heavens, or down into atoms? To conceive a digital library as a collection of a million books may restrict analysis to only one level of granularity. In this paper we examine the consequences and opportunities resulting from a shift in scale, where the desired...
