Cluster Computing: A High-Performance Contender

W hen you first heard people speak of Piles of PCs, the first thing that came to mind may have been a cluttered computer room with processors, monitors, and snarls of cables all around. Collections of computers have undoubtedly become more sophisticated than in the early days of shared drives and modem connections. No matter what you call them—Clusters of Workstations (COW), Networks of Worksta...

Contender: A Resource Modeling Approach for Concurrent Query Performance Prediction

Predicting query performance under concurrency is a difficult task that has many applications in capacity planning, cloud computing, and batch scheduling. We introduce Contender, a new resourcemodeling approach for predicting the concurrent query performance of analytical workloads. Contender’s unique feature is that it can generate effective predictions for both static as well as adhoc or dyna...

Multidetector helical CT angiography: poor cousin or contender?

CT angiography (CTA) is an intriguing example of a seemingly new imaging method that is a modern application of a technique first proposed in the nascent years of CT. Development of CTA was necessarily deferred until the advent of helical (spiral) CT scanning to achieve its promise as a noninvasive angiographic alternative to MR angiography (MRA). The first references in our literature to its a...

A second contender for “world’s smallest fly” (Diptera: Phoridae)

Background Flies of the family Phoridae (Insecta: Diptera) are amongst the most diverse insects in the world, with an incredible array of species, structures and life histories. Wiithin their structural diversity is the world's smallest fly, Euryplatea nanaknihali Brown, 2012. New information A second minute, limuloid female phorid parasitoid fly (Diptera: Phoridae) is described. Known from a...
