This class is offered as CS6290 at Georgia Tech where it is a part of the [Online Masters Degree (OMS)](http://www.omscs.gatech.edu/). Taking this course here will not earn credit towards the OMS degree. The course begins with a lesson on performance measurement, which leads to a discussion on the necessity of performance improvement. Pipelining, the first level of performance refinement, is reviewed. The weaknesses of pipelining will be exposed and explored, and various solutions to these issues will be studied. The student will learn hardware, software, and compiler based solutions to these issues.

The goal of this course is to give you solid foundations for developing, analyzing, and implementing parallel and locality-efficient algorithms. This course focuses on theoretical underpinnings. To give a practical feeling for how algorithms map to and behave on real systems, we will supplement algorithmic theory with hands-on exercises on modern HPC systems, such as Cilk Plus or OpenMP on shared memory nodes, CUDA for graphics co-processors (GPUs), and MPI and PGAS models for distributed memory systems. This course is a graduate-level introduction to scalable parallel algorithms. “Scale” really refers to two things: efficient as the problem size grows, and efficient as the system size (measured in numbers of cores or compute nodes) grows. To really scale your algorithm in both of these senses, you need to be smart about reducing asymptotic complexity the way you’ve done for sequential algorithms since CS 101; but you also need to think about reducing communication and data movement. This course is about the basic algorithmic techniques you’ll need to do so. The techniques you’ll encounter covers the main algorithm design and analysis ideas for three major classes of machines: for multicore and many core shared memory machines, via the work-span model; for distributed memory machines like clusters and supercomputers, via network models; and for sequential or parallel machines with deep memory hierarchies (e.g., caches). You will see these techniques applied to fundamental problems, like sorting, search on trees and graphs, and linear algebra, among others. The practical aspect of this course is implementing the algorithms and techniques you’ll learn to run on real parallel and distributed systems, so you can check whether what appears to work well in theory also translates into practice. (Programming models you’ll use include Cilk Plus, OpenMP, and MPI, and possibly others.)

In this course, we will study the emergence of the major civilizations of the ancient world, beginning with the Paleolithic Era (about 2.5 million years ago) and finishing with the end of the Middle Ages in fifteenth century A.D. We will pay special attention to how societies evolved across this expanse of timefrom fragmented and primitive agricultural communities to more advanced and consolidated civilizations. To do this, we will rely upon textbook readings to provide historical overviews of particular civilizations and then utilize primary-source documents to illuminate the unique features of these individual societies. By the end of the course, you will possess a thorough understanding of important overarching social, political, religious, and economic themes in the ancient world, ranging from the emergence of Confucian philosophy in Asia to the fall of imperial Rome. You will also understand how many aspects of these ancient civilizations continue to remain relevant in today’s world.

Only 150 years ago, the empires and states of Northeast Asiafor many centuries far more developed than their contemporaries in most of Asia, and all of Europe, the Americas and Africafound themselves powerless in the face of the military, technological and economic might of the European imperialist powers and the United States. Yet, today, most of these states have once again become key players in the contemporary world order: economically, politically, culturally, and, in many instances, militarily. In this course, we will study how and why the ‘modern’ transformation of Northeast Asia came about, examining both the indigenous and foreign ideas and institutions on which the transformations were based, and comparing how change manifested in different times and places. We will analyze many of the problems faced both domestically and internationally during this transformation, and will evaluate the prospects for the region in the 21st century. In order to do so, we will trace the political, economic and c…

This course will introduce you to the history of Africa from 300,000 BCE to the era of European imperialism in the nineteenth century. You will learn about the major political, economic, and social changes that took place in Africa during this period and examine the experiences of Africans who lived during this period. You will also explore the relationships between Africans and people living in other regions of the world. The course will be structured chronologically except for units 3 and 4, which will divide the continent geographically while covering the classical period of African history. Each unit will include representative documents and other resources that illustrate important overarching political, economic, and social themes. By the end of the course, you will understand how Africans transformed their continent beginning with human evolution and concluding with the era of global capitalism. The story then continues in HIST 252, which covers the last 120 years of African history.
