How to Build a Beowulf


Book Description

This how-to guide provides step-by-step instructions for building aBeowulf-type computer, including the physical elements that make up aclustered PC computing system, the software required (most of which isfreely available), and insights on how to organize the code to exploitparallelism. Supercomputing research—the goal of which is to make computers that are ever faster and more powerful—has been at the cutting edge of computer technology since the early 1960s. Until recently, research cost in the millions of dollars, and many of the companies that originally made supercomputers are now out of business.The early supercomputers used distributed computing and parallel processing to link processors together in a single machine, often called a mainframe. Exploiting the same technology, researchers are now using off-the-shelf PCs to produce computers with supercomputer performance. It is now possible to make a supercomputer for less than $40,000. Given this new affordability, a number of universities and research laboratories are experimenting with installing such Beowulf-type systems in their facilities.This how-to guide provides step-by-step instructions for building a Beowulf-type computer, including the physical elements that make up a clustered PC computing system, the software required (most of which is freely available), and insights on how to organize the code to exploit parallelism. The book also includes a list of potential pitfalls.




Write Like this


Book Description

If you want to learn how to shoot a basketball, you begin by carefully observing someone who knows how to shoot a basketball. If you want to be a writer, you begin by carefully observing the work of accomplished writers. Recognizing the importance that modeling plays in the learning process, high school English teacher Kelly Gallagher shares how he gets his students to stand next to and pay close attention to model writers, and how doing so elevates his students' writing abilities. Write Like This is built around a central premise: if students are to grow as writers, they need to read good writing, they need to study good writing, and, most important, they need to emulate good writers. In Write Like This, Kelly emphasizes real-world writing purposes, the kind of writing he wants his students to be doing twenty years from now. Each chapter focuses on a specific discourse: express and reflect, inform and explain, evaluate and judge, inquire and explore, analyze and interpret, and take a stand/propose a solution. In teaching these lessons, Kelly provides mentor texts (professional samples as well as models he has written in front of his students), student writing samples, and numerous assignments and strategies proven to elevate student writing. By helping teachers bring effective modeling practices into their classrooms, Write Like This enables students to become better adolescent writers. More important, the practices found in this book will help our students develop the writing skills they will need to become adult writers in the real world.

Beowulf


Book Description

A New York Times Bestseller. Composed toward the end of the first millennium of our era, Beowulf is the elegiac narrative of the adventures of Beowulf, a Scandinavian hero who saves the Danes from the seemingly invincible monster Grendel and, later, from Grendel's mother. He then returns to his own country and dies in old age in a vivid fight against a dragon. The poem is about encountering the monstrous, defeating it, and then having to live on in the aftermath. In the contours of this story, at once remote and uncannily familiar at the beginning of the twenty-first century, Seamus Heaney finds a resonance that summons power to the poetry from deep beneath its surface.
