Experience with ADI-FDTD Techniques on the Cray MTA Supercomputer

Finite difference, time domain (FDTD) simulations are important to the design cycle for optical communications devices. High spatial resolution is essential, and the Courant condition limits the time step, making this problem require the level of high-performance system usually only available at a remote center. Model definition and result visualization can be done locally. Recent application o...

Evaluating the networking characteristics of the Cray XC-40 Intel Knights Landing-based Cori supercomputer at NERSC

There are many potential issues associated with deploying the Intel Xeon PhiTM (code named Knights Landing (KNL)) manycore processor in a large-scale supercomputer. One in particular is the ability to fully utilize the high-speed communications network, given the serial performance of a Xeon PhiTM core is a fraction of a Xeon® core. In this paper we take a look at the tradeoffs associated with ...

A Study of High Performance Computing and the Cray SV1 Supercomputer

Some Geographical Applications of Genetic Programming on the Cray T3D Supercomputer

The paper describes some geographical applications of a parallel GP code which is run on a Cray T3D 512 processor supercomputer to create new types of well performing mathematical models. A series of results are described which allude to the potential power of the method for which there are many practical applications in spatial data rich environments where there are no suitable existing models...

At most at last

Recent pragmatic accounts derive the ignorance inferences to which superlative modifiers give rise as quantity implicatures in a neo-Gricean framework. While these approaches successfully account for the interaction of at least with modals, the behavior of at most remains a puzzle. I propose that at most is composed of an antonymizing operator and at least and show how this accounts for the int...
