Nanofabrication using a stencil mask
We describe tests of a technique to fabricate nanostructures by the evaporation of metal through a stencil mask etched in a suspended silicon nitride membrane. Collimated evaporation through the mask gives metal dots less than 15 nm in diameter and lines 15–20 nm wide. We have investigated the extent of hole clogging and the factors which determine the ultimate resolution of the technique. © 19...
متن کاملCoding Stencil Computations Using the Pochoir Stencil-Specification Language
Pochoir is a compiler for a domain-specific language embedded in C++ which produces excellent code from a simple specification of a desired stencil computation. Pochoir allows a wide variety of boundary conditions to be specified, and it automatically parallelizes and optimizes cache performance. Benchmarks of Pochoir-generated code demonstrate a performance advantage of 2–10 times over standar...
متن کاملA Generic Library for Stencil Computations
In this era of diverse and heterogeneous computer architectures, the programmability issues, such as productivity and portable efficiency, are crucial to software development and algorithm design. One way to approach the problem is to step away from traditional sequential programming languages and move toward domain specific programming environments to balance between expressivity and efficienc...
متن کاملOptimizing Data - Parallel Stencil
We have developed a communication optimizer that concentrates on stencil communication patterns. This optimizer has been done in the context of the UNH C* compiler that targets distributed-memory MIMD computers. Our work has two distinguishing features: The compiler/optimizer is designed to be highly portable. We achieve this goal by providing eecient support for the optimizations in the run-ti...
متن کاملAdvanced Stencil-Code Engineering
This report documents the program and the outcomes of Dagstuhl Seminar 15161 “Advanced Stencil-Code Engineering”. The seminar was hosted by the DFG project with the same name (ExaStencils for short) in the DFG priority programme “Software for Exascale Computing” (SPPEXA). It brought together experts from mathematics, computer science and applications to explore the challenges of very high perfo...
