—Accurate clock skew budgets are important for microprocessor designers to avoid hold-time failures and to properly allocate resources when optimizing global and local paths. Many published clock skew budgets neglect voltage jitter and process variation, which are becoming dominant factors in otherwise balanced-trees. However, worst-case process variation(More)
—We show that distributed Infrastructure-as-a-Service (IaaS) compute clouds can be effectively used for the analysis of high energy physics data. We have designed a distributed cloud system that works with any application using large input data sets requiring a high throughput computing environment. The system uses IaaS-enabled science and commercial(More)
An account of the genus Ipomoea L. in Bolivia is presented. 102 species are recognised in the country and each of these is described. Notes are provided on diagnostic features, distribution, habitat, phenology and conservation status. A dichotomous key to all species is provided together with additional informal keys focussing on outstanding features of(More)
