A multigrid perspective on the parallel full approximation scheme in space and time
For the numerical solution of time-dependent partial differential equations, time-parallel methods have recently shown to provide a promising way to extend prevailing strong-scaling limits of numerical codes. One of the most complex methods in this field is the “Parallel Full Approximation Scheme in Space and Time” (PFASST). PFASST already shows promising results for many use cases and many mor...

هدف از انجام تحقیق حاضر، مطالعه و بررسی نقش زنان و مردان در دو مجموعه از کتابهای درسی انگلیسی در قالب تحلیل گفتمان انتقادی و همچنین، بررسی و آشکار ساختن اصول ایدوئولوژیکی مربوط به نقش زنان و مردان در این کتابها است. این دو مجموعه کتاب عبارتنداز: کتابهای انگلیسی سال دوم و سوم دبیرستانی ایران و کتابهای تاپ ناچ 2آ و 2ب. برای انجام این منظور، مدل تحلیل گفتمان انتقادی فرکلاف مورد استفاده قرار گرفته ...
15 صفحه اولA numerical scheme for space-time fractional advection-dispersion equation
In this paper, we develop a numerical resolution of the space-time fractional advection-dispersion equation. We utilize spectral-collocation method combining with a product integration technique in order to discretize the terms involving spatial fractional order derivatives that leads to a simple evaluation of the related terms. By using Bernstein polynomial basis, the problem is transformed in...
متن کاملA Parallel Multigrid Method Using the Full Domain Partition∗
The combination of adaptive refinement, multigrid and parallel computing for solving partial differential equations is considered. In the full domain partition approach, each processor contains a partition of the grid plus the minimum number of additional coarse elements required to cover the whole domain. A parallel multigrid algorithm using the full domain partition is presented. Multigrid ra...
