Study Notes

High Performance Computing (HPC) is a practice of aggregating computing power to solve large problems in science, engineering, simulation, modeling, or big data analytics.
HPC involves multiple interrelated disciplines, including technology, methodology, and application, to achieve the greatest computing capability at any given time.
Scientific simulation and modeling, complex physical phenomena, biological complex systems, and complex social behaviors require greater computing power as single-core processors cannot handle the resources needed.
Parallel computing is a solution to the heavy load in serial/sequential computing by dividing up the work among numerous linked systems.
Making processors with faster clock speeds or putting huge memory on a single processor is difficult due to cost and power/heat limitations.
