The BlueGene/L supercomputer will use system-on-achip integration and a highly scalable cellular architecture to deliver 360 Teraflops of peak computing power. With 65,536 compute nodes, BlueGene/L represents a new level of scalability for parallel systems. As such, it is natural for many scalability challenges to arise. In this paper, we discuss challenges in the area of system management and ...
BlueGene/L is a massively parallel cellular architecture system with a toroidal interconnect. Cellular architectures with a toroidal interconnect are effective at producing highly scalable computing systems, but typically require job partitions to be both rectangular and contiguous. These restrictions introduce fragmentation issues that affect the utilization of the system and the wait time and...
Evolution of Lindenmayer Systems (L-Systems) provides a powerful method for creating complex computer graphics and animations. This paper describes an interactive modelling system for computer graphics in which the user is able to “evolve” grammatical rules and surface equations. Starting from any initial L-System grammar the evolution proceeds via repeated random mutation and user selection. S...
abstract abstract of thesis (includes summary, goals, execution methods, and results) story “al-obnosat al-bayza” is one of the short stories from “hanna mineh” collection. this story is a selection of lives of some humans during a voyage together, each of them is a symbol of human nature (love, mind, kindness) and examine social, cultural, and political aspects of governing system, and it...
A deterministic L system generates an infinite word α if each word in its derivation sequence is a prefix of the next, yielding α as a limit. We generalize this notion to arbitrary L systems via the concept of prefix languages. A prefix language is a language L such that for all x, y ∈ L, x is a prefix of y or y is a prefix of x. Every infinite prefix language determines a single infinite word....
in this thesis,spin dependend transport and electron transport through of ng/sg(graphene/ superconductor graphen) are studied in the junction of ng/fgt/sg. due to andreev reflection conductance increases in the presence of superconductor graphene.also, by applying a voltage gate on a superconductor, fermi level shifts and the conductance is independent of ferromagnatic substrate. also, the cond...
Background: Multiple sclerosis (MS ( is one of the chronic autoimmune diseases of the central nervous system with unknown etiology. Nitric oxide (NO) as a free radical has contradictory effect on the central nervous system and on MS disease. Nitric oxide is one of the distractive factors of the immune system and is a factor in the destruction of myelin. On the other hand, there is an interact...
Angiotensin-converting enzyme (ACE) inhibitors including quinapril could exert a protective effect on cardiovascular system through endothelial system in normoglycemic and diabetic rats. The present experimental work was designed to study the vascular reactivity of aortic ring segments isolated from streptozotocin (STZ)-diabetic rats treated for 4 weeks with nitro-L-arginine-methyl ester (L-NAM...
The weekly averaged DIRBE full sky images have been processed to separate the various components contributing to the total brightness in the various bands. The zodiacal emission, which dominates at 12 and 25 #m and the zodiacal dust scattering at ~ < 5 #m are both accounted for using an empirical fit to the data. The diffuse stellar emission which dominates at )~ < 5 #m is determined using the ...
