Heterogeneous Systems Architecture - a new compute platform infrastructure presents a next-generation hardware platform, and associated software, that allows processors of different types to work efficiently and cooperatively in shared memory from a single source program. HSA also defines a virtual ISA for parallel routines or kernels, which is vendor and ISA independent thus enabling single source programs to execute across any HSA compliant heterogeneous processer from those used in smartphones to supercomputers.

The book begins with an overview of the evolution of heterogeneous parallel processing, associated problems, and how they are overcome with HSA. Later chapters provide a deeper perspective on topics such as the runtime, memory model, queuing, context switching, the architected queuing language, simulators, and tool chains. Finally, three real world examples are presented, which provide an early demonstration of how HSA can deliver significantly higher performance thru C++ based applications. Contributing authors are HSA Foundation members who are experts from both academia and industry. Some of these distinguished authors are listed here in alphabetical order: Yeh-Ching Chung, Benedict R. Gaster, Juan Gómez-Luna, Derek Hower, Lee Howes, Shih-Hao HungThomas B. Jablin, David Kaeli,Phil Rogers, Ben Sander, I-Jui (Ray) Sung.

Search has been vital to artificial intelligence from the very beginning as a core technique in problem solving. The authors present a thorough overview of heuristic search with a balance of discussion between theoretical analysis and efficient implementation and application to real-world problems. Current developments in search such as pattern databases and search with efficient use of external memory and parallel processing units on main boards and graphics cards are detailed.

Heuristic search as a problem solving tool is demonstrated in applications for puzzle solving, game playing, constraint satisfaction and machine learning. While no previous familiarity with heuristic search is necessary the reader should have a basic knowledge of algorithms, data structures, and calculus. Real-world case studies and chapter ending exercises help to create a full and realized picture of how search fits into the world of artificial intelligence and the one around us.

*Provides real-world success stories and case studies for heuristic search algorithms *Includes many AI developments not yet covered in textbooks such as pattern databases, symbolic search, and parallel processing units

Hidden semi-Markov models (HSMMs) are among the most important models in the area of artificial intelligence / machine learning.

High Acid Crudes quickly gets the refinery manager and all other relative personnel up to date on this particular type of feedstock by providing an overview and relevant details of the identification of high acid crudes and their influence on the refinery’s process units, especially regarding corrosion potential. Covering the types, effects on the various refining units, and proper acid stripping techniques, High Acid Crudes effectively trains refinery personnel with a quick reference guide for day-to-day use in today’s refineries.

Due to their discounted value but potential for higher production rates, refineries are accepting more of high acidic crude feedstocks, otherwise referred to as “opportunity” or “challenging” crude oils. Refining of these resources is still increasing due to high oil prices, with China dominating this market and doubling their production of high acid crudes by 2015. Processing these resources can significantly increase any refinery’s productivity, but knowledge and proper training for the refinery manager and crude supplier is key to reducing the risk that is commonly associated with high acid feedstocks, while still maintaining clean production standards.
