This chapter introduces the Graphics Processing Unit (GPU) architecture and all
the concepts needed to understand how GPUs work and can be used to speed up the
execution of some algorithms. First of all this chapter gives a brief history of
threads are different from traditional threads for a CPU. In
Chapter~\ref{chapter2}, some examples of GPU programming will explain the
details of the GPU threads. Threads are gathered into blocks of 32
-threads, called warps. These warps are important when designing an algorithm
+threads, called ``warps''. These warps are important when designing an algorithm
for GPU.
