Communications in Binary Fat Trees
نویسندگان
چکیده
Fat trees are built around complete b-ary trees but have processing nodes only at the leaf level and may have different branch capacities in different levels. In this paper we study the communication capabilities of binary fat trees (including the simple binary tree) with respect to five major communication operations: broadcasting, multinode broadcasting, scattering, gathering and total exchange. We present and analyse optimal and nearly optimal algorithms for the five operations.

A New Heuristic Algorithm for Drawing Binary Trees within Arbitrary Polygons Based on Center of Gravity
Graphs have enormous usage in software engineering, network and electrical engineering. In fact graphs drawing is a geometrically representation of information. Among graphs, trees are concentrated because of their ability in hierarchical extension as well as processing VLSI circuit. Many algorithms have been proposed for drawing binary trees within polygons. However these algorithms generate b...
متن کاملProfile and Height of Random Binary Search Trees
The purpose of this article is to survey recent results on distributional properties of random binary search trees. In particular we consider the profile and the height.
متن کاملHybrid Tree: A Scalable Optoelectronic Interconnection Network for Parallel Computing
The performance of parallel computer systems is increasingly limited by constraints imposed by interconnects and this limitation will inevitably become more serious as capability of each processing node increases. Optics has already proved its worth in telecommunications and more recently in interconnecting computers and computer peripherals. In this paper, we propose an optical hybrid tree net...

This paper reviews P´olya urn models and their connection to random trees. Basic results are presented, together with proofs that underly the historical evolution of the accompanying thought process. Extensions and generalizations are given according to chronology: • P´olya-Eggenberger’s urn • Bernard Friedman’s urn • Generalized P´olya urns • Extended urn schemes • Invertible urn schemes ...
متن کاملProbabilistic analysis of the asymmetric digital search trees
In this paper, by applying three functional operators the previous results on the (Poisson) variance of the external profile in digital search trees will be improved. We study the profile built over $n$ binary strings generated by a memoryless source with unequal probabilities of symbols and use a combinatorial approach for studying the Poissonized variance, since the probability distribution o...
