 The Fat Tree   (Site not responding. Last check: 2007-10-29)
Processors may be interconnected by a tree structure, in which the processors are at the leaves of the tree, and the interior nodes are switches.
A Fat Tree is a tree structure with redundant interconnections on its branches; the number of interconnections increases as the root is neared.
The Fat Tree is the principal interconnection structure for the CM-5.

 Fat tree - Wikipedia, the free encyclopedia
Unlike an ordinary computer scientist's notion of a tree, which is skinny all over, the links in a fat-tree become "fatter" as one moves up the tree towards the root.
By judiciously choosing the fatness of links, the network can be tailored to efficiently use any bandwidth made available by packaging and communication technology.
In contrast, most communication networks, such as hypercubes and meshes, have communication requirements that follow a prespecified mathematical law, and therefore cannot be tailored to specific packaging technologies.

 WINTER AND MIGRATORY WEIGHT AND FAT FIELD STUDIES ON SOME NORTH AMERICAN BUNTINGS   (Site not responding. Last check: 2007-10-29)
Fat is known to be a ready source of reserve energy in birds, furnishing twice the energy per gram produced by carbohydrate metab- olism.
Fat deposition during fall and spring is not found in non-migratory species (Baldwin and Kendeigh, 1938), or in non- migratory populations of migratory species (Wolfson, 1945).
Fat of all birds on the 14th was nearly one half-class higher than on the 15th, although this could be attributed to small sample size and normal variation.

The eucalyptus regnans, described by foresters as "very fat", has a girth of 18.7 metres and stands 79 metres tall, making it one of the largest trees known in the state.
Calculated to contain more than 300 tonnes of wood, the fat tree is also estimated to be more than 300 years old.

 Tree::Fat - Perl Extension to Implement Fat-Node Trees
Tree performance is enhanced by balancing array operations with tree operations.
An experiment is performed to compare these trees with standard AVL trees and with balanced trees on the basis of mean retrieval time, of amount of restructuring expected, and on the worst case of retrieval time.
AVL trees with relaxed balance were introduced with the aim of improving runtime performance by allowing a greater degree of concurrency.

While high in total fat, tree nuts are a rich source of unsaturated fats that have important health attributes.
Tree nuts may also eventually prove to be effective in protecting against certain forms of cancer.
As the research on tree nuts continues to grow, it appears that eating a handful (one ounce) of mixed nuts a day, as part of a healthy diet, may help curb the appetite and provide other health benefits.

 Transit Note #32 Practical Schemes for Fat-Tree Network Construction
The connections from the subtree unit tree stacks into the parent node unit tree stacks are dispersed as widely as possible; that is, physical channels from a single unit tree in the bottom tree are spread out as evenly as possible to all unit trees comprising the parent nodes.
From channel capacity arguments, we see that the number of unit trees in a parent stage is always a factor of four smaller than the number of unit trees in the immediate child stage, as long as unit trees of the same size are used in both stages.
Latency in the unit tree based network is superior to the latency of a naive implementation of a fat-tree network in a number of ways.

We call the tree ``fat'' because the capacities of the channels grow by a factor of 2 at every level.

The algum tree is spoken of as a valuable exotic product imported to Palestine by Hiram's and Solomon's fleets (1 Kings 10:11; 2 Chronicles 2:8; 9:10), suitable for fine joinery and making musical instruments (1 Kings 10:12; 2 Chronicles 9:11).
The olive tree was considerred the symbol of fruitfulness, blessing, and happiness, the emblem of peace and prosperity.
The palm tree flourishes now only in the maritime plain, but the Jordan Valley, Engaddi, Mount Olivet, and many other localities were renowned in antiquity for their palm groves.

Implements object-oriented trees using algorithms adapted from b-trees and AVL trees (without resorting to yucky C++).
Fat-node trees are not the best for many niche applications but they do have excellent all-terrain performance.
If N is the maximum size the tree could ever have, we prove that each insertion gives rise to at most floor(log_phi(N + 3/2) + log_phi(sqrt(5)) - 3) rebalancing operations and that each deletion gives rise to at most floor(log_phi(N + 3/2) + log_phi(sqrt(5)) - 4) rebalancing operations, where phi is the golden ratio.

 Force10 Networks: Cluster/Grid Computing   (Site not responding. Last check: 2007-10-29)
The basic building block of Myrinet is a 16 port crossbar switch chip that is assembled in fat tree networks to build larger switches and switch arrays.
QsNet and QsNetII switches are based on fat trees assembled from 8 port crossbar switch chips with port speeds of 3.2 Gbps and 10.6 Gbps respectively.
Full fat tree switch configurations for large clusters involves a large number of switch chassis and a considerable amount of cabling, as illustrated in Figure 4, which shows a typical topology for a 1,024 node cluster build using a total of 24 node and top switches with 128 ports each.

 FatNemo: Building a Resilient Multi-Source Multicast Fat-Tree   (Site not responding. Last check: 2007-10-29)
Fat-trees are like real trees in that their branches become thicker the closer one gets to the root, thus overcoming the ``root bottleneck'' of regular trees.
FatNemo organizes its members into a tree of clusters with cluster sizes increasing closer to the root.
It uses bandwidth capacity to decide the highest layer in which a peer can participate, and relies on co-leaders to share the forwarding responsibility and to increase the tree's resilience to path and node failures.

 8 Conclusion
Situations in which a mesh might be used include systolic array computation [15, 17] and image processing.
As a practical matter, it is probably not worth worrying whether every set of memory accesses is conservative with respect to the input, as long as the load factor of memory accesses is not much greater than the input load factor.
For example, a contraction tree is not conservative with respect to its input tree (though the levels of the contraction tree are), but the load factor of the contraction tree is at most

 callipygian: Ask Dr TreeĀ™ - Muscle/Fat Myths Part I
I was going to post a rant about all the people who believe that muscle weighs more than fat and that muscle can magically transmogrify into fat and that lifting weights makes you look unfeminine.
The woman who lifts weights is going to decrease her percentage of body fat much more than the woman who does hours and hours of cardio.
Imagine one fat molecule to one muscle molecule, not in terms of kilograms, which is a weight measurement.
