High Performance Computing MCQ Unit – 2 | HPC MCQ

High Performance Computing MCQ Questions and Answers UNIT – 2 What is High performance computing ? HPC – High Performance Computing is the use of parallel processing for running advanced application programs efficiently, reliably and quickly. The term applies especially to systems that function above a teraflop or 1012 floating-point operations per second. The term HPC is occasionally used as a synonym for supercomputing, although technically a supercomputer is a system that performs at or near the currently highest operational rate for computers. Some supercomputers work at more than a petaflop or 1015 floating-point operations per second.
