The magical world of parallel computing awaits you! We all know Serial computing using our favourite mainstream programming language( C, C++, Java, Python ) on a single faithful CPU with a module of RAM of a standard PC, one machine instruction after another. (Don't fret even if you don't! We'll discuss concepts gradually transitioning from serial processing to concurrency to parallelism and beyond!) Now, suppose we have a 2.0 GHz single core CPU, so it is capable of about 2 billion instructions per second. Compare that to Human calculation time, about 2 seconds per instruction !!! (assume simple addition or relocation instruction) What if we want more than that? Just visit the closest computer hardware store and buy another PC with: n processors with m cores, x.yz GHz Superscalar architecture, Hyper threading, etc r GB GDDR5 RAM and s GB SSD Integrated Graphics and Discrete Graphics card with abcd GPGPU cores (Wauw, that is possibly going to
