  1. Validity of the single processor approach to achieving large scale computing capabilitiesGene M. Amdahl Literature Review Dongdong Chen Peng Huang

  2. Introduction • Single VS Multiple • Interconnection of computers • Validity of the single processor approach • Weakness of the multiple processor approach

  3. Arguments Description • Statistical characteristics of computation • The fraction of the computational load is constant (~40%). • Sequential ( unlikely to be amenable to parallel processing technique)

  4. Arguments Description • Physical Problems • Irregular boundaries • Inhomogeneous interior • Computation maybe dependent on the states of the variables at each point • Propagation rate may be quite different • The rate of convergence may be strongly dependent on sweeping through array.

  5. Conclusion (1) Amdahl’s Law

  6. Amdahl’s Law (Con)
