OpenMP
Before we begin with OpenMP, it is important to know why we need parallel processing. In a typical case, a sequential code will execute in a thread which is executed on a single processing unit. Thus, if a computer has 2 processors or more ( or 2 cores, or 1 processor with HyperThreading), only a single processor will be used for execution, thus wasting the other processing power. Rather than letting the other processor to sit idle (or process other threads from other programs) we can use it to speed up our algorithm.
