Raymond Tay - OpenCL Parallel Programming Development Cookbook

Raymond Tay has been a software developer for the past decade and his favorite programming languages include Scala, Haskell, C, and C++. He started playing with GPGPU technology since 2008, first with the CUDA toolkit by NVIDIA and OpenCL toolkit by AMD, and then Intel. In 2009, he decided to submit a GPGPU project on which he was working to the editorial committee working on the "GPU Computing Gems" to be published by Morgan Kauffmann. And though his work didn't make it to the final published work, he was very happy to have been short-listed for candidacy. Since then, he's worked on projects that use GPGPU technology and techniques in CUDA and OpenCL. He's also passionate about functional programming paradigms and their applications in cloud computing which has led him investigating on various paths to accelerate applications in the cloud through the use of GPGPU technology and the functional programming paradigm. He is a strong believer of continuous learning and hopes to be able to continue to do so for as long as he possibly can.

This book could not have been possible without the support of foremost, my wife and my family, as I spent numerous weekends and evenings away from them so that I could get this book done and I would make it up to them soon. Packt Publishing for giving me the opportunity to be able to work on this project and I've received much help from the editorial team and lastly to the reviewing team, and I would also like to thank Darryl Gove The senior principal software engineer at Oracle and Oleg Strikov the CPU Architect at NVIDIA, who had rendered much help for getting this stuff right with their sublime and gentle intellect, and lastly to my manager, Sau Sheong, who inspired me to start this. Thanks guys.

Seyed Hadi Hosseini is a software developer and network specialist, who started his career at the age of 16 by earning certifications such as MCSE, CCNA, and Security+. He decided to pursue his career in Open Source Technology, and for this Perl programming was the starting point. He concentrated on web technologies and software development for almost 10 years. He is also an instructor of open source courses. Currently, Hadi is certified by the Linux Professional Institute, Novell, and CompTIA as a Linux specialist (LPI, LINUX+, NCLA and DCTS). High Performance Computing is one of his main research areas. His first published scientific paper was awarded as the best article in the fourth Iranian Bioinformatics Conference held in 2012. In this article, he developed a super-fast processing algorithm for SSR in Genome and proteome datasets, by using OpenCL as the GPGPU programming framework in C language, and benefiting from the massive computing capability of GPUs.

Special thanks to my family and grandma for their invaluable support. I would also like to express my sincere appreciation to my wife, without her support and patience, this work would not have been done easily.
