 This book is intended to present the design of significant scientific
 applications on GPUs. Scientific applications require more and more
 computational power in a large variety of fields: biology, physics,
-chemisty, phenomon model and prediction, simulation, mathematics, etc.

 In order to be able to handle more complex applications, the use of
 parallel architectures is the solution to decrease the execution

 Nevertheless using parallel architectures is not so easy and has always required
 an  endeavor  to  parallelize  an  application. Nowadays  with  general  purpose
 graphics processing units (GPGPU), it  is possible to use either general graphic
 cards or dedicated graphic cards to  benefit from the computational power of all
-the cores  available inside these  cards. The NVidia company  introduced Compute

 Unified Device Architecture (CUDA) in 2007 to unify the programming model to use
 their video card. CUDA is currently  the most used environment for designing GPU

 The programming model of GPU is quite different from the one of
 CPU. It is well adapted to data parallelism applications. Several
