Fat tree

The fat tree network, invented by Charles E. Leiserson of MIT, is a universal network for provably efficient communication. Unlike an ordinary computer scientist's notion of a tree, which has "skinny" links 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 communications technology. In contrast, other communications networks, such as hypercubes and meshes, have communication requirements that follow a prespecified mathematical law, and therefore cannot be tailored to specific packaging technologies.

Uses

The Connection Machine Model CM5 supercomputer (circa 1990) used a fat tree interconnection network.

Mercury Computer Systems used a hypertree network, a variant of fat trees, in their multicomputer. From 2 to 360 compute nodes would reside in a circuit switched fat tree network, with each node having local memory that could be mapped by any other node. Each node in this heterogeneous system could be an Intel i860, a PowerPC, or a group of three SHARC DSPs. The fat tree network was particularly well suited to the FFT, which customers used for signal processing tasks like radar, sonar, medical imaging, and so on.

Tree (data structure)

In computer science, a tree is a widely used abstract data type (ADT)--or data structure implementing this ADT--that simulates a hierarchical tree structure, with a root value and subtrees of children with a parent node, represented as a set of linked nodes.

A tree data structure can be defined recursively (locally) as a collection of nodes (starting at a root node), where each node is a data structure consisting of a value, together with a list of references to nodes (the "children"), with the constraints that no reference is duplicated, and none points to the root.

Alternatively, a tree can be defined abstractly as a whole (globally) as an ordered tree, with a value assigned to each node. Both these perspectives are useful: while a tree can be analyzed mathematically as a whole, when actually represented as a data structure it is usually represented and worked with separately by node (rather than as a list of nodes and an adjacency list of edges between nodes, as one may represent a digraph, for instance). For example, looking at a tree as a whole, one can talk about "the parent node" of a given node, but in general as a data structure a given node only contains the list of its children, but does not contain a reference to its parent (if any).

Tree (Gaelic Storm album)

Tree is a 2001 album by Gaelic Storm.

Track listing

Beggarman, Black is the Colour, New York Girl, An Poc Ar Buile, and Go Home Girl are traditionals. Beggarman, which is played fast, is a standard in their live set list and features a didgeridoo very prominently. Black is the Colour, sung by guitarist Steve Twigger, is very slow and mournful, reminiscent of the original composition from the previous album She Was the Prize. An Poc Ar Buile is the band's first venture in the Irish language. The song is normally slowly sung, but Gaelic Storm puts a twist into it by singing it fast, complete with hoots and hollers. Go Home, Girl is a faster tune about a girl who falls in love with a gypsy, only to have her advances turned down for an ironic reason.

Law & Order: Special Victims Unit (season 7)

The seventh season of the television series, Law & Order: Special Victims Unit premiered September 20, 2005 and ended May 16, 2006 on NBC. It aired on Tuesday nights at 10:00 p.m. Critically the show's most successful season, both lead actors received nominations at the 2006 Emmy Awards with a win by Mariska Hargitay.

Production

Repeating a pattern established by other SVU seasons, the Season 7 premiere was filmed before the airing of the Season 6 finale. Long-time SVU co-executive producers, Michele Fazekas, Tara Butters, and Lisa Marie Petersen departed the series at the end of Season 7. Additionally, long-time Law & Order franchise director Constantine Makris departed until his return in the twelfth season.

Mariska Hargitay won the Primetime Emmy Award for Outstanding Lead Actress in a Drama Series for her performance in the episode "911". This made her the first regular cast member of any Law & Order series to win an Emmy. Christopher Meloni was nominated for the Primetime Emmy Award for Outstanding Lead Actor in a Drama Series, his first Emmy nomination. Meloni was water skiing when the 2006 Emmy nominations were announced. He received a congratulatory call from showrunner Neal Baer and responded with "Cool! I'm going back to ski." Sources are not consistent about whether the episode submitted for Meloni's nomination was "Raw" or "Ripped". The Envelope section of The LA Times reported that SVU also made a bid for Ted Kotcheff to receive the Primetime Emmy Award for Outstanding Directing for a Drama Series, but he was not selected as a nominee.

Fat (song)

"Fat" is a song by "Weird Al" Yankovic. It is a parody of "Bad" by Michael Jackson. It is Yankovic's second parody of a Jackson song, the first being "Eat It", a parody of Jackson's "Beat It". "Fat" is the first song on Yankovic's Even Worse album.

The video won a Grammy Award for Best Concept Music Video in 1988.

Concert version

When performing in concert, Yankovic wears a fat suit and a mask that makes his face appear fat. Due to undergoing laser vision correction surgery, he no longer needs to wear glasses, though he wears glasses with non-prescription plastic lenses in order to help hold on the mask.
