Introduction
نخطط هنا لتحسين تطبيق تحويلات فورييه السريع (إف إف تي) على تصميمات بناء اجهزة الحوسبة عالية الأداء المستجدة، وحشد المجتمع الدولي من الخبراء لقياسه بجهودنا وجهودهم، للوصول الى اعتماد تكنولوجية برمجيات (إف إف تي) التي هي الأسرع والأكثر كفاءة. هناك حاجة لا حصر لها لأجهزة الكمبيوتر التي يمكن أن تحسن التنبؤ العلمي والتصميم الهندسي من خلال زيادة الدقة ( بزيادة الذاكرة) وتقليل مرات التنفيذ (بالاكثار من المعالجات المتزامنة) مع متطلبات طاقة أقل (تكون أكثر ملاءمة للبيئة وأوفر إقتصاديا). حدود السرعة المقبلة لكل من خصائص بناء اجهزة الحوسبة العالية الأداء الثلاثة السابقة هي سرعة الإكساسكيل أي ١٠**١٥ عملية في الثانية بحدود ١٠**١٥ كلمة في الذاكرة. تحويل فورييه السريع (إف إف تي) هو لبنة بناء أساسية للخوارزميات في العلوم الحاسوبية والهندسة. وله تعقيدات تشغيلية تنمو بشكل أسرع قليلا من حجم بيانات المدخلة

We present mpi4py.futures, a lightweight, asynchronous task execution framework targeting the Python programming language and using the Message Passing Interface (MPI) for interprocess communication. mpi4py.futures follows the interface of the concurrent.futures package from the Python standard library and can be used as its drop-in replacement, wh...
Article
The fast Fourier transform (FFT) has applications in almost every frequency related study, for example, in image and signal processing, and radio astronomy. It is also used as a Poisson operator inversion kernel in partial differential equations in fluid flows, in density functional theory, many‐body theory, and others. The three‐dimensional FFT ha...

The fast Fourier transform (FFT) has applications in almost every frequency related studies, e.g. in image and signal processing, and radio astronomy. It is also used to solve partial differential equations used in fluid flows, density functional theory, many-body theory, and others. Three-dimensional \(N^3\) FFT has large time complexity (O( N^3 l...
Chapter
To determine the best method for solving a numerical problem modeled by a partial differential equation, one should consider the discretization of the problem, the computational hardware used and the implementation of the software solution. In solving a scientific computing problem, the level of accuracy can also be important, with some numerical m...

Preprint
An Arabic old translation of a supercomputer getstarted English version flyer that I have prepared in 2015. It could benefit those who don't know English.
Conference Paper
Full-text available
An overview of concerns observed in allowing for reproducibility in parallel applications that heavily depend on the three dimensional distributed memory fast Fourier transform are summarized. Suggestions for reproducibility categories for benchmark results are given.
Article
Full-text available
The cubic Klein-Gordon equation is a simple but non-trivial partial differential equation whose numerical solution has the main building blocks required for the solution of many other partial differential equations. In this study, the library 2DECOMP&FFT is used in a Fourier spectral scheme to solve the Klein-Gordon equation and strong scaling of t...
Article
Full-text available
In this paper, we consider a general conformal mapping function with complex constant coefficients, to solve the elasticity problems for an infinite plate weakened by a curvilinear hole. Conformal was used outside and inside of a unit circle in the presence of an initial heat flowing perpendicular to the plate. The use of the complex variable metho...
Article
We used a rational mapping function with complex constants to derive exact and close expressions of Goursat functions for the first and second fundamental problems (plane elasticity problems) of an infinite plate weakened by a hole having arbitrary shape. Notable, the area outside the hole is conformally mapped outside a unit circle by means of the...
Article
Here, we used a rational mapping function with complex constants in order to study the effect of complex constants. Also, a complex variable method have been applied to deduce exact expressions for Gaursat functions for the first and second fundamental problems of an infinite plate weakened by a hole having arbitrary shape. The edge of the hole is...

Complex variable method (Cauchy integral method) has been applied to derive exact and closed expressions of Goursat functions for the first and second fundamental problems for an infinite plate weakened by a curvilinear hole. The area outside the hole with the hole itself is con- formally mapped on the right half-plane by the use of a rational mapp...
