Program Performance Michelle

Many scienti c applications require sparse matrix computations. For example, Finite Element modeling and N-body simulations. It is di cult to write these codes in a portable way which also achieves high performance because of the sparsity of the matrices and because current architectures have deep memory hierarchies and multiple levels of parallelism. Therefore the implementation of such comput...

A Broader Definition of Riba

The paper analyzes different interpretations of riba and discovers that the main source of confusion about the concept has been misunderstanding of riba in hadith in general and riba in barter exchange with a time lag, hereafter called riba in barter loans, in particular. A majority of jurists has, so far, either overlooked riba in barter loans or has included it in the category of trivial riba...

The Michelle Electron Gun and Collector Modeling Tool*

The 3D finite-element gun and collector modeling code, MICHELLE, has been under development at SAIC in collaboration with industrial partners and national laboratories (ref. 1). This development program has been designed to address the shortcomings of current beam optics simulation and modeling tools for vacuum electron devices. The program specifically targets problem classes including gridded...
