(a) Approximate the time required to execute the forward phase of GaussJordan
Chapter 9, Problem 5(choose chapter or problem)
(a) Approximate the time required to execute the forward phase of GaussJordan elimination for a system of 100,000 equations in 100,000 unknowns using a computer that can execute 1 gigaflop per second. Do the same for the backward phase. (See Table 1.) (b) How many gigaflops per second must a computer be able to execute to find the -decomposition of a matrix of size 10,000 10,000 in less than 0.5 s? (See Table 1.)
